I noticed a small hole in the rear brake dust cover. I bought a kit for £30. It was too hot to diy in the summer. Now it too cold to do it. I decided to go to several garages including a merc dealer. all refused to do a few minutes job. They keep telling me, a brake caliper swap is the only solution they are willing to do. How frustrating I have to wait for the summer by that time the brake caliper will be contaminated. one garage even told me because of insurance thing they wont touch it!
