HELP HELP!!!

rebuild the caliper .

Check that the fluid is returning back to the master cylinder .

Done all that

Only had this problem since replacing the pads. Now pads are absolutely rooted

One of the pins is probably bent or corroded.

Replace them.

But that doesn't explain why is just does it on its own without even using the bike at all

May be fluid level is too high and you have pressure in system even with brake pedal not pushed. This situation occurs when brake level was set before before replacing old thin pads by new (thicker).

Could be the new pads aren't fitting correctly and causing bind. Stick the old pads back in and see if problem is still there.

I took it all apart today and cleaned and greased it all, I did happen to notice a notch in the pin.

If the hydralic system is overfilled, the brake pads will eventually make firm contact with the rotor, and if hot enough, it can lock up.

Happened few times while riding, the wheel completely locks up. Rotor glowing. Might try new pin take some fluid out and set of new pads. Thanks for your help

Just open the top, spill out a little, and close it back up and try it.

Put new pads in yesterday and couldn't even push the piston back in. Also put new pads in the front. Pistons went in easy. Think it's time for another MC

crack the bleeder and try pushing it in . The piston may be sticking.

Yes that did work

The return fluid port sounds plugged. Take the master cyl top off and put fluid through the caliper bleeder. It will put fluid in master, so take some fluid out.

Put another mc in, big difference. Really easy to prime. Havnt riden it yet though. Hopefully that has fixed the problem
