Misterbuickguy Posted August 9, 2019 Share Posted August 9, 2019 (edited) I just recently purchased a 96 Suburban K1500 4x4. It's loaded with all the 'bells and whistles' including the ABS system. Having never driven a vehicle with this system, I am having quite a time adjusting to this braking system. I will be using this van for towing. The brakes are presently very soft. This after replacing the front calipers, pads and rear brake shoes and bleeding the entire brake system. I have not started towing yet, but the low 'soft' pedal has me really worried. Previously, I had an 89 4x4 that would stop on a dime No ABS. I understand there were problems with this system. some people simply remove it; other replace the module. I'd like to hear from users in this group on the best advice on what to do to achieve a firm pedal. Thanks to ALL for your help!!

plymouthcranbrook Posted August 13, 2019 Share Posted August 13, 2019 Although not directly applicable i can tell you that all the smaller hydraulic Chevy and GMC School buses I have driven have had a low mushy pedal. From years 2000 to about 2009.They are based on 3/4 and maybe larger chassis and I have been told by the mechanics that that s how they are. I personally have had a few bigger Chevys and not experienced that issue though. Link to comment Share on other sites More sharing options...
Misterbuickguy Posted August 13, 2019 Author Share Posted August 13, 2019 Thanks for your insight. I may have ti live with this, but will continue to wish others can provide some additional info. I have been told that some people have actually removed this setup for better braking. We'll look into that as well. Link to comment Share on other sites More sharing options...
Misterbuickguy Posted August 14, 2019 Author Share Posted August 14, 2019 Can't I get more help on this topic?? Really need to resolve the issue with these soft, spongy brakes. I plan to tow in the next several weeks and I'm wondering if this ABS system is a help or hindrance???? All help-thoughts-suggestions, experience with this brake system is appreciated.

Studeous Posted November 25, 2019 Share Posted November 25, 2019 This is a common problem with these abs systems. Find a competent shop with a scan tool that can sequence (exercise) the abs system. This is necessary to eleminate all the air. I bought a suburban, well maintained and cared for, the neighbor I got it from said it has always had a low pedal. They tell me thats normal on these trucks. After getting the system bled with a scanner it was better- not as soft but still kinda low pedal. Harking back to oldentimes I put a good tight shoe adjustment on the rear drums and that improved the pedal height a bunch. It wasnt a high firm pedal but it was a pretty high firm pedal. Something I could live with, so to speak. Link to comment Share on other sites More sharing options...
