I need to find out why the brakes are binding, if i push the bike forward its OK. If on the other hand I need to push backward especially with the wheel pointing to the right it would stop. so lets overhaul the calliper.
Very manky inside.
The steel piston was badly pitted.
Brake fluid has damaged the seal.
New bearings ready to fit.
Clean new seal and stainless steel piston fitted.
Re-route the brake line as I still have the
binding issue, must be some thing else.
