My mechanic installed parking brake pads on my 2007 BMW 530i. I pulled the handle up as far as I could BUT it didn't stop the car from moving. I brought the car back to him and he checked the pads and he had to remove the discs a second time and adjust the pad adjuster as close as possible BUT everything was the same. Before fitting, he even said that these shoes are not of very good quality. it seems he was right.
