5043W57T17-RC8-R
The RC8-R uses the same friction material as the standard RC8, but with a grooved backing plate to reduce the contact area with the piston to provide a radiator effect. This patented shape was created to reduce heat transfer through the piston and into the brake fluid.
Average friction coef. :
µ = 0,60
