Brakes problem
1993 Chevy Suburban V8 Two Wheel Drive Automatic 150k miles
----------------------------------------------------------------
When at a complete stop the brake pedal tends to go slowly down to the floorboard. I have replaced the master cylinder 3 times, bleed the system numerous times until all the air was out of the system, changed power booster and I still have the same problem. Today I put a metal clamp on the hose that goes to the booster and it did help a little bit but I still have the same problem. Do I need to replace the hose? I looked through your Q&A and I've done just about everything you've suggested within the last month. Any help would be appreciated.
thanks.
