Rear Disc Brake Brackets

[BigChevMan]

In reference to this thread (http://www.fullsizechevy.com/forum/showthread.php?s=&threadid=39021) I contacted the producer of these brackets and he is willing to offer our members a group purchase discount.

"For 5-10 sets, I'll let them go for $70.00 a set for 10+ I can drop to $65.00 a set, but things tend to get slim from there on. I may be able to do better depending on the interest. Definatly let me know!!"

That is a direct quote from his email. I know I'll be ordering a set.

Me_TOBSTER is in for 2 sets..so that's already three.

Anyone else?

[CKTA]

Whats the total cost for ALL the parts and will it have an E-brake worked into it?

I may be in for 2 also.

Yeah, what he said, but only one set.

[TribalVision]

I am interested as well. But I will need part numbers for the rest of the conversion. No time to search junkyards to see what fits. This has to be cheaper than the Stainless Steel Brake's kit

Exactly, I know the SSBC is nice and worth the money. I researched some of the "kits" some of the guys in here put together and to do it right and nice it would cost more then the SSBC kit.

[BigChevMan]

Ok...here's what I know. For the 6 lug trucks it's a direct bolt on. For 5 lug trucks you'll need to have the rotor redrilled for a 5 lug pattern...or you could order a set of replacement rotors from ssbc or the like. I priced the rear rotors at autozone and they were like 26 bucks each. To me it's worth it to get them redrilled

For the caliper you have a couple different choices.

Calipers:
There are two different styles of calipers that will work with these
brackets. The first style has an integral manual parking brake on the caliper, the second style has no provision for a parking brake. They are as follows:

1979-1984 Cadillac Deville rear disc caliper (integral manual parking brake)
1979-1981 Cadillac Eldorado rear disc caliper (integral manual parking
brake)
1982-1995 Chevrolet S10 front caliper Delco Part # 18R625 & 18R626 (NO Parking Brake)


I priced the Caddy Calipers completely loaded from Autozone and they are around 200 bucks for the set. If you could find a set of cores cheaper then you would ge around 70 bucks back.

Installation is straightforward and simple...remove the drum hardware and install the brackets, rotors, and calipers.

No need to mess with bearings or any of that sort of stuff. The only recommended upgrade is to install a stainless flexible hose because the caliper moves as the pads wear and it can mess with your hard lines. I have a picture of the kit installed with the s-10 calipers....I'll upload it in a minute.

Another words....any GM stock ones?

[BigChevMan]

no..no stock rotors that are five lug and will fit. You have the other option of using a stock front rotor and having the axle hat machined down to fit inside the rotor hat.

The kit uses 88-91 k-1500 4wd rotors....like I said..they are 6 lug and will need to be redrilled for 5 lug. I'm checking now how much it'll cost to have them redrilled..but it shouldn't be much.

If you have access to a drill press I would recommend doing it yourself.

Just for comparision....the deville calipers are 65 bucks each plus a 20 dollar core...then you would need the pad set...for around 20 bucks...so your looking right at 200 bucks for the caddy calipers.

The s-10 calipers are 12 bucks each with a 14 dollar core....a set of pads for 10 or 15 bucks and your only out 70 bucks.

So if your willing to forget the parking brake you could be out for under 225 bucks with everything. You could always later add a driveshaft parking brake or a line lock if you really wanted a parking brake.

Stock rotors off of what? Not our trucks. Also, how can you wachine the front rotor down? It has the provisions for the bearings and stuff?:confused:

[BigChevMan]

Stock rotors for the front of your truck doug. the inside diameter of the rotor is smaller than the diameter of the hat where the studs are on your rear axles..so you can pull your rear axles out and have that hat machined down so that it fits inside the rotor and then you wouldn't have to worry about redrilling the 6 lug rotors for your 5 lug pattern.

But your best bet is to have the 6 lug rotor redrilled. I know that you are competent enough to do it. Clean easy and simple.

True, is there enough "meat" to redrill safely? If so, who has the X and Y cordinates? I guess I could get them off the drums if I had too.:)

[BigChevMan]

well...here is the Stainless steel brakes kit...so I would guess so...

http://www.stainlesssteelbrakes.com/product.images/550.1.jpg

Here is the TSM Kit

http://www.tsmmfg.com/GM%205%20Lug%20web%20ver.JPG

They both use redrilled rotors on the basic kits....

[BigChevMan]

I don't understand why the TSM kit redrilled different than the ssbc kit....it looks like they drilled completely different holes while the ssbc kit used one of the stock hole from the 6 lug holes...I would drill it like the ssbc kit if it was me...that one hole on the TSM kit looks way too close to the edge for me.

[Vince]

OK, let me see if I have all of this right. To do the conversion, and keep the parking brake I would need:

Plates: $70
1979-1984 Cadillac Deville rear disc calipers and pads: $200
88-91 k-1500 4wd rotors: $52
Stainless lines: $20 ??

Total: ~$350

Does this look right?

[BigChevMan]

Yup...basically a fairly easy and straightforward deal...especially since you have a 4wd.

[CKTA]

So if we don't have the 10 guys intersted.....what's the price?:confused: I'm stillnot sure on this, I got info from the guy and a proportioning valve should be used. I think there is more nickle and dime stuff to this that will make a totally complete 600 SSBC kit look even better.:confused:

Hopefully this link will work. Here is the firm feel master cylinder that truckperformance.com suggests to be used with a rear disc upgrade.

http://www.truckperformance.com/products/?productID=895161&option=1

But, no place do they mention the use of a new proportioning valve. I think I do remember reading someplace that a new valve should be used to put more pressure to the back brakes.

[Kruznlow69]

i realize i'm a bit late in that game here but interested in a bracket kit too!!!, I run a repair shop so i can get everything for cost...

for a '97 2dr 2wd tahoe i will need.....


-bracket plates..

-caddi calipers, (reman or new) + new pads

-5 lug front rotors (I can machine axle hats down correct?)
-would rather machine to ease future rotor swaps

-new flexible brake lines near calipers..

questions i have****

*are cadi calipers gonna bolt up to brackets and fit correctly with stock 97 chevy front rotors? (after machining axle hats)

*what do the barckets mount to on the axle itself?


thankyou guru's!!!

[sack]

just so you know i had gone over this in class about 2 months ago, the reason why those conversion kits are soo much is a lot of the custom parts, but a new master cylinder is also included.
The new master cylinder is to even out the brakes.

with drum brakes it the rotors start to get pushed out a lot earlier since it has to push them soo far to the drums to make contact.

with disc brakes the pads themselves are almost always touching the disk unless you have a spring to pull them away from the disk, the amount that they touch is very little and hardly noticable, but it is enough to create a little friction(formula one cars have springs to pull the pads away so there is less friction).

so if you do not upgrade the master cylinder when you convert the back drums to disks, the back wheels will catch a lot faster than the fronts will, in theory. which could be a bad thing(you don't want the back tires to lock up when brakeing hard into a corner), but it could be a good thing too, but you won't have as much control of when the brakes catch.

either way i think i would like to get a pair of those brackets! let me know if and when you might possibly order them!

thanks!

[Kruznlow69]

sorry i had to.. anyways, i got the brake theory, kinda why i'm running a $700,000 7 bay repair shop, I just need some info on these particular brackets!! thanks for helpin though!!!

sack You make some very interesting and valid points but I think maybe you forgot to mention the proportioning valve. :think:

[BigChevMan]

I kinda dropped this one after everyone started hedging on going for it. I have found out some more information though. You can use impala or caprice 9c1 rear rotors for the rear...but once again...i believe you have to machine the axle hat down to fit inside the rotor. I am not positive on this.

And for the record....the ssbc kit doesn't include a new master cylinder...no need for it....you just need to get a proportioning valve from wildwood or someone like that so that the brakes are biased/balanced to your favor. The master cylinder is another 550 dollar upgrade to the kit.

[BigChevMan]

if enough people are still interested in this kit I can contact the guy and see if the prices are still good?

[sack]

the proportioning valve! and what about the metering valve?
i didn't go into this area because i was concentrating mainly on the master cylinder part, but i forgot that these do a lot of work too!

The proportioning valves are one of those safety things, when you slam on the brakes, the proportioning valve will allow only so much psi through, but will cut it off at a certain point so the rear wheels do not lock up.

but the metering valve is another thing, i'm not sure if our trucks have them, i never looked, but the metering valve will cut off the psi going to the front discs at around 10 psi UNTIL the rears reach around 100-125 psi because the rotors have to over come the springs and all the space before they touch the drums themselves. then the discs will get more psi, that way they do not do most of the braking and wear out really fast.

do our trucks have metering valves?

[sack]

i am interested in getting a set, and i know a buddy back home that might also, but it might be a little while until either of us get some money for it, we are college students, that should be enough explaination.

:cool:

[TribalVision]

According to SSBC and 99Escalade( the guy running the group purchase), the rear disc kit for my truck comes with the master cylinder, and does not need the proportioning valve.

here's the thread on the group purchase, and the master cylinder info.

NEW INFO, got email from guy that makes this bracket!

"Wow, I read the thread at the forum and it seems like there is a lot of
interest, but for every person interested, there is a sceptic. The
conversion is very straight forward, and cheap, providing you use the
correct parts.

First of all, there is no machine work required to the axles. The axle
flanges fit perfectly into the hat. The ONLY rotors that will work properly
with the brackets are 88-91 k1500 4x4 front rotors. They have the correct
diameter, thickness, and offset for the brackets. These rotors have a 6 on
5-1/2 lug pattern. If you have a 4x4 with 6-lugs, they will fit without
modification. If you have a 2wd, you have a 5 on 5 lug pattern. The stock
rotors will not bolt up directly. Some people have them redrilled. There
is no possible way to re-drill them without having one of the holes from the
new pattern overlap one of the holes from the old pattern. This bothers
some people, doesn't bother others.

You have two choices of calipers, the caddie calipers that you mentioned,
and a standard front 95 s10 caliper will also work. I used the s10 calipers
on my truck and have not changed a thing with the master cylinder or
proportional valve. The rear will lock up slightly before the front on
gravel, I am going to add a proporting valve to take care of that problem.
I have not changed the MC, and do not believe it is necesarry.

Gary"

[sack]

o.k. so who is all interested in putting down a modest $70(it was around this right?) to purchase a set of brackets?

even if you don't do the brakes right away, at least you have it and could save them for a rainy day project.

I want to do this, who else is in? it's only 70 bucks, not like it's that much money.

put me down for at least 2 sets

[sack]

so nobody??? man, and i thought you people were worried about the safety of the people in your vehicle! what if you couldn't stop in time? you'd have to say, oops, i should have converted the rear to discs! . . . oh well last call anyone?

[baddoggz71]

I might be interested, let me get this straight. $70 for 2 brackets to convert rear drum to disk. These bolt right up to the axle? I dont have to remove the axle to install the bracket? Then I need to supply calipers, rotors, and stainless lines? You can emailme if its easier.

[sack]

from what i have gathered you buy the bracket for like 70-80 and that mounts without taking the axles out or anything else apart.

from there you need the calipers and pads from the front of a '95 S-10 (like 70-80 bucks total)

or the rear of some caddy if you want a manual emergency brake('cuz the front does not have a hookup for a cable override), (like 200 bucks total)

but something i thought about is you could get those brake lockers(line lockers, probably 20-30 bucks) and apply the brakes then lock the pads and shut the truck off(which would also work to keep the pressure out meaning you could do massive burnouts without wearing out the back brakes!!!:rocking: )

also, a new proportioning valves to balance out the brake psi.

and the flexible steel lines

and the disc off of the front of a '91 4wd($52) or machine your axles down to accept new 2wd brake discs(i have no clue to this price).

and that should be it, soo 70 for bracket and 70 for S-10 brakes and 40 for line lockers(e-brake) and steel flexible lines oh yea, and discs.. total of les than $250 for the less expensive easier parts way.

[baddoggz71]

If the GP is still going on, im in:D I dont like the damn drum brakes.

[Kruznlow69]

i'm thinking we can still arrange something with this guy.....

baddoggs.... with his brackets, we have to use the 4x4 rotors and drill out the holes from a 6 on 5 to a 5 on 5 lug pattern, we can't use our regular front rotors..

anyone else in??????????????????????????????????????

[Vince]

Count me in. I've been debating on weather or not to do the swap. Since It's time to buy new drums, I guess I can put that money toward the swap. Does the cost of the brackets include shipping?

[sack]

yea dude, count me in, i'm tryin to get a hold of a few more people around my hometown to see if they are interested, but i think i'm just gonna buy an xtra set or two.

so put me down for at least 2(this is what i'll guarantee), could be 3, and if i really tried, maybe 4-5.

[baddoggz71]

Kruznlow69 since mine is a 4x4 already with 6 lugs, i will have no drilling, right? But I am in, what do i do next.

[Vince]

Is this gp going to happen? :read:

[sack]

i think we are going to have to get ahold of the origional person that started this and get the info from him and do this ourselves.

bogus.

so we'd have one set a piece for:

95Tahoe
baddoggz71
kruznlow69

and i'll be getting at least two(workin on another buddy for him to get a set) possibly 3. wasn't that all we needed for the 70 dollar price?:D

[Vince]

Here's an auction for some cadillac calipers:

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2411720270&category=33563

I think he has six sets left. I'm waiting until I'm sure that the gp for the plates is going to go through before I buy any calipers.

[sack]

nice score! i was going to go for the S-10 brackets, but those are way better, and there are plenty to go around!! nice!

but i emailed the "big chevy guy" and asked if he was the one that was organizing all this and if he has the info still.

too bad we just picked up on this now though, they were trying to do this back in november err somethin like that.

[sack]

i just got news that the offer for the disc brake brakets is still on the table!!

all that are seriously interested please reply and mention how many sets you will need.

the going rate is 70 a set and around 10 for shipping. remember we need at least 5 sets to get this price.

[baddoggz71]

Ill take one set. But I cannot pay till next friday.. I get paid every 2 weeks:bawl: If thats ok, Ill be in for a set

I'm still interested.(one set):read:

[Vince]

Well, it looks like this GP isn't going to happen. I emailed the guy who sells the brackets, and he said he would sell me a set for $80 +$10shipping. I guess I will just pay the full price for them.


As far as the installation goes, if anybody is wondering, you will have to remove your axles to get the original backing plate off. Here's a link to the The Street Rod Manufacturing Company site: http://www.tsmmfg.com/2532.htm They sell kits, and have the indtructions posted on this site.They also give a parts list. I think I am going to buy the stainless lines and the parking brake cable extension from them. Anybody find any good deals on the Cadillac calipers? I've seen some on ebay, which is where I will probably get them from.

[sack]

i was just waitin 'til that one guy got his paycheck and posted that he had the money available, and myself and my buddy are still interested.

but i'll be going back to my hometown in a week and i don't have any work right now due to finals, so i won't have the money for a lil while, but i suppose that another 10 bucks isn't bad at all if we do not buy them as a group.

how did you get ahold of him? so when i'm ready i'll get the 2 sets from him.

Well I think I have gathered up all the parts I need to do the conversion, and I am going to attempt it this weekend. I will try to take some pictures, but I can't guarantee anything. Once I start working, and get my hands all dirty, I'm not going to want to stop to clean them and take pictures.
