Hi All,
Could anyone tell me if the rear brake piston is a Left or Right hand thread? I am purchasing the wind back tool tomorrow and dont fancy wasting the time changing the wrong purchase.

Some links here with pics......Wind the handle clockwise - same for both sides of the car, until the piston is fully retracted:
