What is the correct master cylinder for manual disc
Use the 73 power brake master cylinder which is 15/16 inch bore. Unless you like using two legs to stop your car don't use a larger bore MC on a manual brake car.
Also I recently switched to 13/16 rear wheel cylinders and rebuilt front KH calipers. Still running the same master cylinder. Pressure bled with Motive pressure bleeder. Adjustable prop valve now set to full pressure to rear brakes. Balanced braking with minimum leg effort. Running EBC red pads up front. Car stops great.
