Anyone around slapding good with brakes?

ive rebled mine twice and they still dont work, a mate of mine said that i may have screwed the master cyclinder and maybe naffed up a diapphragm inside.

Help? its looking like a new master cylinder but if it can be fixed i'd much rather that.

tea and biscuits waiting,

Depends how you've bled it; sometimes pressure (pedal) bleeding doesn't work - try a vacuum based system (I use a Mityvac). Worked on one of my cars with a wierd split system - and was the only thing that did.

Rolling a seal is a possibility (which is probably what he's on about), but normally only after one's been rebuilt without the new seals being well lubricated with fluid.
