2wd 350ci auto.180,000mls dont put on many miles a yr. yr ago f-brakes seem to be hanging..and the front pass. pulling to the right when applied..like at times real bad put on brakes pull quick to the right..like left one not working..I worked cal. back and forth/pump brakes then go and push cal back in on pass side after several times seemed to release. drive 1 mile then checked .released and cool..drivers side hot as H. and stuck..So went and replaced Both..bled up on blocks..seems like cant pump brakes without enjine running. pedal hard as a rock..and with engine running everytime release pedal engine like speeds up then back..and both brakes stuck again..??? so now what replace? I put over 100 in so far..Booster/master/lines??? also do you have to bleed different cuz of the anti lock thing..just did it the old way..

2 things can cause this, contaminated brake fluid swells the M/C seals and causes blockage of the bypass port, second is collapsed brake hoses.
