Today I went to my mates garage, and had the rear brakes replaced on my Mk3 Tourer 2009. First the EPB was left in the off position and the car switched off. The pads, caliper bracket and discs were removed. then the pistons were wound back using left and right handed wind back tools, new discs and pads installed. Now the mechanic pumps the brakes, then started the car and engaged the EPB. The park brake light came on as usual then flashed. The EBP was released, and the mechanic press the brake pedal and then press the EBP button again. The park brake light flashed again, so the mechanic switched off the engine. He switched it on and released the EPB. He pumped the brakes, then applied the EPB and it came on as normal. No electronic resetting tools or diagnostics needed. I had my Launch diagnostic tool which can reset the EPB, but did not use it. I had Apec brakes fitted, same as the fronts fitted a couple of weeks ago. Hope this answers a few queries regarding changing rear brakes without affecting the EBP on early manual T27s.
