I just went to discs the middle of June. I believe these are '04 models. Once again the downside of mail order components surfaces.
A couple of weeks ago I took a digger and afterward my front brake has quit working. There was no obvious damage to the brake body (master cylinder) or lever but I must have whacked it when I went down.
The lever would pull all the way to the grip. It develops internal pressure but quickly loses it. Pumping does not correct it.I've re-bled the brake half a dozen times and that didn't fix it so I figure I have damaged my master cylinder. There are no leaks anywhere on the outside of the system.
Yeah I can send it to Hayes but with the freight and the waiting either I will fix it myself or replace the cartridge in the master cylinder.
I downloaded the tech sheets from Hayes on how to service the master cylinder and I tie into the job of disassembly of the brake. I get the cartridge out of the brake body. There was a very small amount of fluid on the bladder but don't appear to be any holes and it appeared that the bladder was in place.
Here's my question, I want to get the piston out of the cartridge but I can't remove the rubber boot that's over the pushrod on the end of the master cylinder. The instructions say to "pull it off over the push rod." I have pulled on the boot to the point that if I continue I'm afraid I'll tear it so I backed off.
There is supposed to be a snap ring behind the boot that has to be removed so that the piston can be removed from the cartridge. Without removing that boot I can't get to the snap ring.
Anybody know how to get that boot off without damaging it?
Also anybody got any ideas as to what I've done to the thing?
Thanks in advance for any suggestions anyone may have.
