Brake issue
 

So I just picked up a 1994 Silverado 2wd single cab. It was bought as a project and once we got it unloaded we noticed some funky stuff with the brakes.

Here is what’s going on. Brakes are a little spongy but work fine and I can figure that out but the part that has me looking for help is the pulsating it’s doing when completely stopped. This is not a rotor issue as it happens when sitting completely still at a red light, stop sign, etc.

If I try and brake torque the truck it will kick the brake pedal back so hard it nearly kicks my foot off. The truck idles fine and runs great.

So could this be dirty/bad ABS sensors? I don’t get an ABS light or anything that I’ve noticed. Any thoughts?

The soft feel is a complaint about there years a lot. Some People adapt the 99 up master cylinder to help with it. The pulsing thing does sound like the ABS. MY 92 seemed to feel the pulsing more than my 94 and 96. They all had 200k+ when I sold them and it never failed or went weird on me.

Thanks for the reply. I have a feeling it is the ABS system as well.

Guess I’m going to replace the wheel sensors and go from there

First thing I think of is somehow related to the power brake booster. Is there something going on there?

Would check into the booster as well. Have a 94 C1500 ext cab since new. ABS only on rear brakes. Cannot remember seeing any rear wheel sensors when doing brakes, no electrical to axle at all IIRC. Old school first gen ABS.
