94 Jimmy Brakes....please help

[demotim00]

I recently bought a 94 Jimmy, and the brake pedal seems lower than what it should. There are no braking noise and it still stops on a dime, and after looking at the brakes, front and rear, they seem to be in good shape about 75% left to the pads. When reading the owner's manual, it says if it happens to go in reverse and apply the brakes firmly a few times to realign the brakes, however it does no good. Has anyone been through this problem thereself? Is there a problem, or is it I am just not used to it? Ive owned 2 S-10 Blazers in the past, a 85 and an 89 and never had a problem with the brake pedal being low. Any advice on this is welcome.

The rear self-adjusting brakes only adjust in reverse. That is why the owner's manual tells you to apply the brakes in reverse. The issue is that if they are out of adjustment, you need to do it more than a few times.

A low brake pedal can be caused by the rears being out of adjustment. It can also be caused by air in the lines or in some cases there is play at the master cylinder.

First thing is to adjust the rears by hand not with the reverse method. You should be able to feel the brakes drag when you rotate the tire by hand. If you do not feel any drag, the brakes are out of adjustment. Also bleed the brakes to make sure there is no air in the lines.

I have owned my 90 GMC K1500 since new and I am the only one to work on it. I have learned to adjust the rear brakes by hand every tire rotation to keep the pedal adjusted properly. The self adjusters do not do a good enough job.
