Good morning all, got a weird problem with back brake, the wheel spins freely ie. brake not dragging but after awhile of riding bike the rear brake fails due excessive heat it will work when it cools down again. Brake pistons are free and new pads have been fitted can the abs modulators cause problems ( abs is disconnected via removed relay ) also can I bypass rear brake modulator without buying new brake lines ect. ?
Cheers

Your rear master cylinder may not be returning to the correct position and preventing the fluid having a way of expanding when it warms up. On the brake lever in front of the M/C there is a socket head grub screw (allen screw) turn that out a bit and that will allow the M/C to return to the home position. There are several other things that could be wrong but give that a try first it is often the problem.

Anti clockwise looking at the end you put the key.

If it does work put somr locktite on the thread to prevent it turning again.
