Product details

A 0.7 inch bore brake master cylinder for the SR3 pedal box. Two brake master cylinders sit behind the pedal, one per circuit, fed through the balance bar. The bore sets how much line pressure a given pedal effort makes: this one sits between the 5/8 inch and 3/4 inch versions, so match the size already on the circuit you are replacing unless you are deliberately changing pedal feel or bias.
