3.7.1 General information

3.7.1.1
The 911 GT3 Cup (991 II) is equipped with a dual-circuit brake system with two
separate master cylinders. Brake balance between front and rear axle can be adjusted
with the help of a balance beam using a knob in the vehicle's interior.
The brake is a racing brake by "Performance Friction Brakes" (caliper, internally vented
discs and pad) which is suitable for long-distance driving and was developed by
Porsche Motorsport. Six piston fixed calipers are provided on the front axle, four piston
fixed calipers in monoblock design on the rear axle. Brake pistons of different sizes
are in use on the brake caliper, which prevent diagonal wear of the brake pads. The
brake discs are vented and slotted steel brake discs.
