So I have just changed the pads on my XOs. The rear was fine but the front has lost all power. I removed the old pads, re-set the pistons, fitted the new pads and the lever now just pulls to the bar. It looks like the left side piston is not moving. Have I buggered the piston or do they just need a bleed?
Any help would be appreciated as I am at Mayhem this weekend!
