    Soft brake pedal


    Support FSC and see no ads! - Click Here
    The Yukon has a really soft brake pedal. You have to push it about halfway down to really start feeling the brakes and I can damn near push the pedal to the floor before the ABS barely kicks in. Fluid is fine and I've got brand new front rotors and pads. Could this possibly be a master cylinder going south? I may have it looked at tomorrow. I need to do it soon because we've got a 4 month warranty on it that's about gone.

    My '96 has gone pretty low since day one. I'm not ruling out the diaphram in the booster, but even w/ new brakes all around my '96 feels way different then my '94.

    Yeah, I forgot to add that it's been this way since we got it. But compared to my mom's '94 and my '91, it just doesn't feel right. You think I should have someone look at it?

    Have the dealership look at it being it is under warranty. Most likely they will tell you it's normal tho.;)

    odd...Did they do something to the brakes on the Vortec trucks to jack them up or something?

    I can pump these a couple times and they tighten up a bit...

    No, I won't take it to the dealer to have it looked at. I'll go to the shop I always use for brakes/exhaust since they know me well and will tell me the truth.

    How much did that run?

    Hmph on my 98 you have to push down quite a bit as well before you start getting some stoppage, but I was told that is normal for Chevy trucks.

    My hoe is the same way. If I drive the S-10 or the Prelude then get in the hoe I feel like I damn near have to stand on the brakes to get it to stop. The brakes on our body style trucks are junk from the factory and it sure doesn't help when you slap them on a heavy SUV.

    My truck is the same way as yours. I have always thought that it was the master cylinder. I have one off of a 97 that I was going to put on mine, but now I don't know.

    ditto, not sure why, I asked this question months ago with a poll and the answers were all over the place. There is a large difference from vehicle to vehicle.

    It sounds to me like the rear brakes need adjusting, if it has rear drum brakes, try that first. I notice the same thing on my 96 Tahoe when the rear brakes need adjusting.

    We had a used 98 Suburban at work and the cutomer kept complaining about the brakes "feeling soft" . We finally took it to a Chevy dealer (I work at a Ford Dealer) and they said that it was normal . I'm not sure what this has to do with anything but the service manual for my truck says to check the power steering fluid level

    air bubbles in the brake line will do that, bleed your brakes then see if that makes a difference. Another reason for a soft pedal would be that the rear shoes need adjusted.

    I bought my Silverado used and my breaks were the first thing I noticed. The peddel was mushy, I had the dealer look at them and they adjusted the rear, it didn't help much. So I took my truck to my machanic and had him look at them, he bled the lines which helped a little. I then needed my intake manifold gasket replaced and an 02 sensor, I asked the mechanic look at my breaks again. This time they feel much better, but still not as great as my wifes 1997 Astro.

    The Astro break peddel has about an inch or so of play and the breaks grab BIG TIME!! I had read on the Internet that the mushy break peddel for the 1996 - 1999 Chevy trucks is designed that way?? I believe there is a better Master Cylinder you can buy ($285.00) to fix the problem. Unfortunately I can't find the Web Site where this was stated.
