I just finished a partial brake job on a 86 240 sedan 125,000, -no ABS-
I replaced front rotors, pads and left front caliper(broke bleeder valve off) and then pressure bled entire system in order Bently lists, twice.
I now have no brakes, (pedal goes to floor), and the "Brake Failure" light is on constantly.
I checked for leaks all over system and found none.
My guess is the master cylinder, but I am confused because there were no problems prior to brake job.
My question:
Is this common? and does this point to the master, or is it a Servo/Booster problem.
How do you diagnose a bad Booster versus a bad master cylinder or is there another area I'm missing.
Also, what does bench bleeding the master mean?
I would appreciate any suggestions
Thanks
Chapster out
