Well, had the drivers side rear caliper start leaking at the emergency brake mechanism. Replaced both calipers with rebuilt units. After that I had no pedal at all, all the way to the floor. Replaced the MC with a new ATE 22mm.unit. I have been bleeding the brakes with a power bleeder at the master cylinder and the old have assistant pump pedal and open bleeder screw. I have worked around the brake system at leaset 10 times and am still getting a slghtly soft pedal. After 1 pump pedal comes back to normal. Checked the brake booster and it operates normally. (hard pedal when car is off) Could this be a bad master cylinder, what have I missed. I have pumped at least 4-5 pints of fluid thru the system.
Anybody got any ideas?
I'm stumped, I've done this procedure before and have never had this much trouble bleeding the brakes. I am getting no air in the bleeder tubes and have even pressurized the system at the MC and let it sit for a couple of hours, there is no brake line leak and the pressure at the bleeder stays at 12-14 psi.
Anybody have this much trouble bleeding the system?
Oh yeah, the car is a 1985 GTV6 with the clutch cylinder tied into the brake master cylinder, and yes I did bleed the clutch too.
