Rear Brake Calipers

Rear Brake Calipers: The single piston floating rear brake calipers are made of zinc-nickel coated spheroidal cast iron. As on the front calipers, the coating satisfies both the increased corrosion protection requirements as well as the European directive for chromium free components (enforced from 7/2003 on). The single piston floating caliper code for the 745i is FN 46/24/345:

- FN - Supplier (continental-Teves)
- 24 - Brake disc thickness (mm)
- 46 - Piston Diameter (mm)
- 345 - Brake disc diameter (mm)
