PORSCHE 911/ 992 TURBO S CERAMIC CERAMIC BRAKE SYSTEM BRAKE NEW

In 2026, the Porsche Ceramic Composite Brake (PCCB) system for the 911 (992) Turbo S is considered the pinnacle of braking technology. Since the Turbo S comes with PCCBs as standard equipment, a “New” set is typically sourced for a Carrera/GTS retrofit or to replace a system that has reached its wear limit (often due to heavy track use).

1. System Components (The Full Set)

A complete new PCCB system for the 992 Turbo S includes:

• Front: 10-piston aluminum monobloc fixed calipers in Yellow (or High-Gloss Black) with $420\text{ mm}$ carbon-fiber reinforced ceramic discs.

• Rear: 4-piston aluminum monobloc fixed calipers with $390\text{ mm}$ carbon-fiber reinforced ceramic discs.

• Pads: Specific PCCB-formula brake pads (identifiable by their larger surface area).

• Hardware: Wear sensors, brake lines, and mounting bolts.

3. Key Advantages for the 992 Platform

• Weight Reduction: The PCCB system reduces unsprung mass by approximately 50% (roughly $20\text{ kg}$ or $44\text{ lbs}$) compared to equivalent cast-iron discs. This noticeably improves steering response and suspension damping.

• Zero Brake Dust: In 2026, this remains the primary reason for many “street-only” owners to stick with or upgrade to ceramic.

• Fading Resistance: Virtually immune to heat-induced brake fade, even during high-speed Autobahn decelerations.

4. Technical Installation & Coding

If you are installing this system on a 992 that originally had steel brakes:

• Master Cylinder: The Turbo S master cylinder is specifically valved for the PCCB fluid displacement. You may need to upgrade the master cylinder to achieve the correct pedal feel.

• PIWIS IV Coding: You must use a Porsche diagnostic tool to change the vehicle’s “VO” (Vehicle Order) to include PCCB. This recalibrates the ABS, PSM (Stability Management), and EBD (Electronic Brake Distribution) logic for the different friction coefficient of ceramic.

• Wheel Clearance: These massive $420\text{ mm}$ front discs require a minimum of 20-inch wheels with specific inner-barrel clearance.

5. Maintenance Warning

While the discs can last over 150,000 miles in normal street use, they are extremely fragile.

Pro Tip: When changing wheels, always use two mounting pins to guide the wheel off the hub. If the inner barrel of the wheel knocks against the edge of the ceramic disc, it can chip the rotor, effectively “killing” a art instantly
