In Reply to: ????why are my brakes on constantly???? posted by bert on April 04, 2001 at 07:57:33:
Since my problem is intermittant, I cannot perform the following, maybe you can:
1. Loosen master cylinder mounting bolts at brake booster. If brakes release, then I would suspect the booster is not returning. Check for pedal obstructions that would prevent the pedal from returning to normal position. Otherwise, suspect a faulty booster.
2. If no changer after step 1, then crack a pressure line or two. If brake(s) release then suspect a faulty master cylinder.
One interesting fact on my car is that the pedal never really feels the same from day to day or stop to stop. I really am leaning toward the master cylinder and possibly a weak accumulator.
And no....don't say because I'm pressing the brake pedal or the emergency brake is on :)
The brakes don't seem to want to retract back.
What could be causing this? Need help desperately!
