Description
- 40mm ATE type calipers
- R2V 1976 > 08/1980 (NOT R45/65)
**Includes piston.
**This upgrade piston is made from anodised aluminium and will not rust and seize like the original is prone to do. 40mm calipers have ’40’ stamped on the outside of the caliper body.
If your caliper is unstamped it will almost certainly have a 38mm diameter piston.
