think i need a master. got a soft pedal. pumps up nice when off but not when running. saw a plug near master. was wondering if anyone knows if this is supposed to be hooked up. looks like it could plug into the booster at bottom. also have old fluid in lines. i bled it and it looked like air was the prob but the bleed didnt work to fix the problem. going to re bleed today with new fluid. also found the cap has an oring in it. was wondering if the messed up seal is a problem.
