Porsche 911 Carrera 992 brake system brake brake 330

For the Porsche 911 Carrera (992 generation), the 330mm brake system is the foundation of the model line. While the higher-trim S and GTS models moved to larger 350mm or 408mm discs, the standard Carrera and Carrera 4 initially utilized this 330mm setup.

1. Technical Specifications (Standard Carrera)

The 992 Carrera brake system is engineered for consistent thermal management and high-speed stability.

• Front Axle:

  • Disc Diameter: $330\text{mm}$

  • Disc Thickness: $34\text{mm}$ (Minimum service limit: $32\text{mm}$)

  • Caliper: 4-piston aluminum monobloc fixed calipers.

  • Finish: Typically finished in Black (standard) or optionally Red.

• Rear Axle:

  • Disc Diameter: $330\text{mm}$

  • Disc Thickness: $28\text{mm}$ (Minimum service limit: $26\text{mm}$)

  • Caliper: 4-piston aluminum monobloc fixed calipers with integrated electric parking brake.

2. Official Part Numbers (Reference)

• Note: Many 992 owners upgrade their discs to Zimmermann “Coat Z” or Brembo UV Coated rotors to prevent the hub from rusting, which is a common visual complaint on standard steel rotors.

3. The “350mm Upgrade” Factor

Starting with the 2024–2025 mid-cycle updates (992.2), Porsche standardized the 350mm front and rear discs for the base Carrera, using the 6-piston front calipers formerly found on the Carrera S.

• If you have a 330mm system: It is likely a 2019–2023 base Carrera.

• Wheel Clearance: The 330mm system is designed to fit comfortably behind the base 19-inch Carrera wheels. If you upgrade to 20/21-inch wheels, the 330mm discs may look visually “small” in the barrel, leading many owners to look for the Red 350mm S-Brake retrofit.

  4. Maintenance & Service Tips

• Piston Retraction: Like most modern Porsches, the rear calipers feature an Electric Parking Brake (EPB). You must use a diagnostic tool (PIWIS, Autel, or OBDLink) to put the car in “Brake Service Mode” to retract the electronic motor before you can compress the pistons.

• Bedding-In: New 330mm discs and pads require a “bedding” period of approximately 200 miles of light-to-moderate braking to transfer a layer of pad material to the disc surface for optimal performance.

• Bolt Replacement: Porsche specifies that the caliper mounting bolts are “stretch bolts” and must be replaced every time the caliper is removed
