The main cylinder leaks so I bought a repair kit from eBay. No instructions though, so I wonderd, is this easy to fix? How do I remove the cylinder? What should I think about? The large rubber thingy that goes over the axel where the pedal is linked to is gone, and that's were is leaks, so my guess is that the rubber on the piston is gone as well. Is there a walk through with pictures somewhere? Or could anyone explain how to do this? Picture the brake repair kit

Should just be two bolts holding the master cylinder to the drivers side of the frame. Carefully take the brake line off the back then disconnect the front linkage. As you disassemble the cylinder, just lay out the pieces as they come out. It's pretty simple to do just take your time and keep everything clean. You will probably have to get a brake cylinder hone and and hone the inside of the master cylinder. If it's pitted badly, you will need to have it bored out and sleeved or find a different one.

I bought a new one off of Amazon of all places for $71.00 shipped. Make sure that your brake lines are in good shape as well - I am changing all of mine to NI copper.
