Good post Robbie. On average when I was not using the car a lot the rear cylinders had to be changed every 2 years. They have been on for 4 years now as the car is used every day. BUT having found the brakes pulling a little in the wet. Inspection has shown that both front Callipers are in need of a re-build. The inboard pistons were seized on both sides. This was not apparent during braking in the dry.
To check I replaced the pads with some very worn ones then got a friend to pump the brakes it then was obvious.
