I was contacted to do Triumph motorcycle brake calipers, and was wondering if I will need to take them apart. I have read about the car calipers and how the rubber can with stand the heat, but nothing about motorcycles. I have also read about cleaning and degreasing, but if they have old finish on them, can I bead blast with alum. ox. and if yes do i just tape off the rubber and piston area. Sorry about being so long winded, but I want to do a good job.
