when i got my shee rear brake set up there was a lot of crap in the master cylinder, line and caliper... well i cleaned them all out with brake fluid and such and put it all back together and bolted mt master cylinder onto my 05 brake pedal and hooked the rest up with a bracket i got off awk for the master, when now my problem is when i push down the pedal it gets stuck and will not return all the way up if at all even when i push a lil bit.............................BUt when i had it off and pushed the piston thing up in the master cylinder it returned back out which would make the pedal return but for some reason it wont when i hook it to the pedal, any suggestions????
