Re: [Chevelle-List] Brake problems part 3 (Darrell)

[Fleshead]

Thanks for your input.
The car was originally driving and braking but the disc brakes were dragging and she locked up. (really cooked them)
Upon inspection it appeared that the driver side had noticable uneven wear  which made me think the caliper was not engaging or releasing properly. I replaced the calipers on both sides including the rubber brake lines and could get very liitle fluid to dribble out. Then I figured I would start working from the top. MC gasket was totally deforemed, so we definitley had some contamination going on up there.
Replaced MC but still no fluid. Cant test Proportioning valve because line is turning with the wrench. and dont have lines yet. Dont know of any changes to the pedal and ordered MC for the car (70 Chevelle SS 396) which when compared, appears correct.
Will replace proportioning valve this weekend and see where that leads me ( Man this little jewel is expensive, dont ever throw one away!)
Will keep everyone updated as more problems occur...Hope to post one last time that she is braking like a champ.

Thx
Ed

I'm popping in late here and may have missed a significant part of the problem definition, but when the master cylinder was replaced are you 1) sure it is the correct MC for your booster or pedal configuration? and 2) was the brake pedal pivot changed or adjusted in any way?   I'm thinking maybe you're not displacing the fluid sufficiently.  Might not be an obstruction at all.
