08 summit xp brake

[sledheadrevxp]

ok heres a new problem that i cant say i have ever had before, i have a 08 summit 800 154x, when i went to pull it out of the shop this winter it had no brakes but did when i parked it. i checked for leaks and none! so i started bleeding it at the caliper and then at the resivoir, after about 30 mins of pissing around i finally got a little bit of pressure and gave up, when i went back the next morning it was gone again so blead it again until it got some pressure and left the park brake locked on and it got more pressure, was almost perfect but then again as soon as i left it over night without the park brake on it went back to nothing, any ideas?

Sounds like the master cylinder is no good.

Check this.....Make sure the clip that rides ontop of the brake pad is ON TOP of the pad and didnt fall between the pads. This wont allow the pad(s) to come together properly and will feel like fade.

SUN Sport is right master cylinder seal is broken.
