Brake problems on 92 silverado

[ProStreet R/T]

What do you mean "bounce" ? Is the pedal pulsing, or is it actually shaking the truck? Does it feel like a vibration, or is it moving around?


Have you checked the bushings in the front end lately? If it's getting sketchy under braking it could be the front end moving around.

How does it feel at highway speed?

I bought a 93 once that was doing that, the front end was shot. After new ball joints, idler/pitman arm, control arm bushings, and tie rod ends it went away. I didn't isolate the particular component that was the culprit because I bought the truck knowing it's condition and that I was going to replace it all anyway.

As was mentioned look over the idler/pitman arm. These trucks eat them like tic tacs.....ball joints almost as bad.

Ive had a dozen or so of these trucks from 88 to 97 and worked on a bunch more and it seems to be a hit or miss on the soft pedal deal. Some trucks have it some dont.

Just to give you an idea...and this is just what I remember off the top of my head:

88 FSRCLB 2wd 350/5spd 85k miles=normal brake pedal feel
90 FSRCSB 2wd 305/auto 280+k miles=soft pedal and nothing I did helped.
89 FSRCSB 4wd 305/5spd 140k miles=soft pedal EXACTLY like the above truck.
93 FSECLB 4wd 350/auto 175k miles=normal pedal
94 FSRCSB 2wd 4.3/auto 130k miles=normal pedal
