1994 Chevy Suburban V8 Four Wheel Drive Automatic 270k miles
The suburban's brakes began feeling inadequate (the rotors, pads and shoes are relatively new). I replaced the right front caliper and hose (was not fully releasing) cut the rotors, sanded the pads (getting rid of any glazing) and thoroughly bled the entire system (replaced fluid as well). The initial bleed was at the replaced caliper followed by the standard routine*.
The pedal still has excessive travel, a semi soft feel and aprox 70% braking ability.
Next I examined the entire system - no leaks and the rear brake area is dry. So I removed and replaced the master cylinder, which was thoroughly benched and re-bled the entire system once more. I don't believe the booster is at fault, I checked it as well.
The pedal is still semi soft with excessive travel and about 70% braking. There is no pulsing in the pedal (like ABS activation). As a matter of fact, I can't brake hard enough to activate the ABS. What is going on here?
PS. There are no lights lit on the dash and all of the
lights are functional.
* Bleeding was accomplished as always beginning at the right rear, left rear, front right, front left.
have the same problem?
