Since we are using a power booster, Wilwood recommended a 1-1/8-inch bore dual master cylinder. We pumped the brake pedal until we had a good firm pedal and tested the brakes by holding the pressure on the brake system for at least one full minute. The conversion proved to be very straightforward and we were more than pleased with the increased rotor size, the black anodized calipers, and the substantial reduction in unspring weight.
