1985 project truck 47k miles. I was having a slight shutter when breaking so I pulled the front calipers to clean and lubricate the brakes. I did not brake the lines, just collapsed the piston. After reinstallation I had a very soft pedal.
Before compressing the pistons I had removed fluid from the master cylinder so it would not overflow. In reading other posts on the list, it seems I should have opend the bleeders, rather than pushing the old fluid back into the master cylinder. But i didn't. Bad on me.
I attempted to bleed the brakes to resolve this but, I am continually getting air out of the lines. I notice lots of entrained air in the fluid in the master cylinder resevoir, and the fluid coming out of the bleeder. When pumping up the brakes, it hisses air out of the closed resevoir. If I press the pedal I with the resevoir open I'll get a shot of fluid up out of the resevoir.
When i got this truck, it was obvious the resevoir had been leaking for a long time. Leaking fluid had eaten the paint off of the bottom half of the booster, and there was a generous layer of old brake fluid on the resevoir. I replaced the the resevoir seal, which was in bad shape, and thought that would cure the leaking resevoir. In hind sight this may have been a long standing problem, although the brakes seemed fine prior to me removing the calipers.
Suggestions?
