I have a RR Corniche 1977.
The offside rear caliper started binding causing the brake disc to
overheat and cook up the rubber seals.Ive replaced pistons 4 and
rubbers but there is still pressure in the lower pistons when I use the
car.which is causing overheating again.
When the car is jacked up,if I apply the brakes without the engine
running the brakes come on and release normally,but if I apply the
brakes with the engine running the bottom pistons of the 4 bind on
,inother words there is pressure remaining in that circuit.If you then
undo the bleed screw the pressure is released.Can anyone help with some
suggestions
Roger
