I recently got myself a 95 vr6 rado. failed mot on corroded and pitted discs and pads and a few ropey copper brake lines. Anyway i replaced every copper brake line, every flexi hose, all discs and pads, rear abs rings. fitted all the parts and bled all the brakes etc. problem is when braking at any speed the front left wheel locks up. checked everything, no abs faults, no air in system, rear load sensing valve is free, no sticking calipers. has anyone any ideas?
