Ok, just picked up a parts rig. Guy sells it because the original master cylinder on the anti-lock system went out. Says brakes were failing due to rusty lines on the rear axle and when the new hard line across the rear axle was replaced, he put a used master cylinder on it.
Currently, there's fluid in all the lines, the reservior is full....... but the brake pedal is hard as a rock - won't move but maybe a 1/4" and then it's solid. He said he bench bled the replacement master so we know the piston/shaft work.
When it's running, and I press on the brake pedal, I can hear some hissing (faint) that changes pitch from when the pedal is pressed to when it's sitting static.
It's seriously like the piston is seized. But there's no pressure to the calipers/cylinders - it rolls around very easily.
Is there some process to bleeding an anti-lock system different than a non-ABS?
Thanks in advance!
