People also ask


What size master cylinder bore for manual disc brakes?


Manual Brakes. If the brake system is manual (no power booster), the master cylinder bore diameter should be less than 1 in., otherwise a very hard pedal will result. A power brake master cylinder will typically feature a larger bore diameter than a manual master cylinder.
