Today replaced the rear discs and pads on the C70. As is my luck it fought me all the way.
Once done I took the opportunity to paint the rear calipers to match the fronts, a pale gold colour that is a fair approximation of the original cad plated finish, and lano sprayed around the rear arch and trailing arm.
Just had the same job done on the Clubman, plus new calipers as one was binding.
