Hmmm we bled the brakes constantly for ages trying to get them back into order, little success.

I pulled the master cylinder down and the seal/cup seems to be pretty good. One thing is, if the master isn't primed it won't get itself going, it's almost like there should be a one way valve at the end of it to stop any air pockets going back into the piston.

So basically if I have the master cylinder in my hand and I pump the piston it produces good pressure, the next pump will keep pressure as long as I keep my finger over the end. Once I leave the end open and pump it a few times it doesn't seem to work.

So is my clutch cylinder faulty or are they just a dog to get going? Could there be an air leak in the brake line that keeps letting air into the system- hence why I can't keep pressure?



EDIT: I'd use the manual I have at home but I'm at uni and between classes, so any help would be much appreciated.
