22-048   4-piston caliper
<< Back 

The 22-048 caliper was originally designed to be used in a two caliper brake system for 125cc bikes. But it was also intended as a brake caliper for light weight cars, as Formula SAE cars. The car version of the caliper has the brake fluid inlet in one of the caps.

This caliper got only 27 mm height of the swept disc area. This means the disc can be made light.
