BRB Big Brake Kits - Brembo 01-04 996 Turbo (Excl PCCB) Front GT BBK 6-Piston Cast 380x34 2pc Rotor Slotted Type3 - Red

The factory braking setup on the 2001–2004 Porsche 991 (996) Turbo was highly advanced for its time, but modern tire compounds and engine tuning have pushed the car far beyond its original limits. If you have bumped up the boost on your Mezger engine or regularly run aggressive track sessions, the stock front brakes will heat up and start showing their weakness. Under repeated hard trail braking, you will feel the pedal get soft as the system struggles to shed thermal energy.The BRB Front Big Brake Kit (Part Number: 1L3.9005A2) replaces that tired setup with a massive, race-proven 6-piston configuration built around Brembo’s premium GT platform. This system swaps out the small stock components for huge, rigid 6-piston monobloc calipers painted in classic high-gloss red. This setup clamps down on massive 380x34mm two-piece floating iron rotors featuring an aggressive Type-3 curved slot pattern. It gives your 996 Turbo the immense, repeatable stopping power of a modern GT3 track car without ruining your brake pedal modulation during casual street driving.The real benefit of this Brembo GT upgrade is how it manages extreme heat. Because the 996 Turbo carries massive speed down straightaways, its front brakes take a brutal beating. The high-carbon 2-piece floating discs separate the iron friction ring from the lightweight aluminum center bells, allowing the outer ring to expand freely under hard thermal cycles without warping. The high-clearance curved Type-3 slots continually clean glaze, gases, and water away from the pad surface, giving you an immediate, uniform initial bite the exact second your foot touches the pedal.

Features and Benefits

Rigid 6-Piston Cast Monobloc Calipers

The radial-mount front calipers are cast from high-strength aluminum as a single, solid piece. This monobloc architecture eliminates the body flex common in multipiece calipers, providing a rock-hard pedal feel and highly precise brake modulation when balancing the car on the absolute limit of grip.

Massive 380x34mm 2-Piece Floating Rotors

The oversized two-piece configuration combines a lightweight aluminum inner hat with a thick high-carbon iron disc. Using floating D-bobbin mounting hardware with anti-rattle springs allows the rotor to expand and contract naturally under extreme track heat, completely eliminating brake fade and steering wheel vibration.

High-Friction Type-3 Aggressive Slotted Face

The advanced curved Type-3 slot pattern provides superior initial bite and continuously sweeps away brake dust, water, and dangerous friction gasses. This ensures the face of your high-performance brake pad stays completely clean for consistent friction levels on every single turn.

Staggered Aluminum Internal Pistons

The calipers incorporate internal pistons with staggered face sizing to distribute mechanical clamping force evenly across the entire surface of the brake pad. This specific configuration stops uneven pad taper and extends the life of your track pads under severe stress.

OEM-Approved Integrated Internal Seals

Built to handle the dual demands of street and track, these calipers feature internal pressure seals combined with durable, OEM-approved outer dust boots. This dual-seal layout keeps road grime, salt, and track debris away from the pistons, preventing leaks and reducing the need for constant maintenance rebuilds.

Vehicle Fitment Matrix

This premium front axle big brake kit is engineered as a direct high-performance upgrade for the following European sports car platform:

Specification	Details
Part Number	BRK.200521
Caliper Type	6-Piston Fixed Radial Mount Forged Caliper
Caliper Finish	High-Heat Industrial Hard Anodized
Rotor Dimension	390mm Outer Diameter × 29mm Thickness
Rotor Style	2-Piece Vented Floating Assembly
Axle Placement	Rear Axle Only (Includes Complete Left and Right Assemblies)
Wheel Requirement	Aftermarket Wheels Only (Does not clear factory stock wheels)

Critical Wheel Clearance Warning: Upgrading your front axle to massive 380mm (15-inch) rotors and wide 6-piston monobloc calipers requires significant internal wheel clearance. This system will NOT fit behind original factory 18-inch Porsche twist wheels. You must run an aftermarket 19-inch wheel profile or an aggressive 18-inch motorsport wheel designed specifically with an open inner barrel profile. Always use Brembo’s official wheel clearance cross-section template to verify that your wheel spokes and inner barrels clear the outer caliper body safely before attempting to mount or drive the car.

Frequently Asked Questions (FAQ)

Will this 380mm big brake kit fit behind my stock 18-inch Porsche Turbo wheels?

No, it will not. The massive outer diameter of the 380mm rotors paired with the wide 6-piston monobloc caliper housing makes it physically impossible to clear the inner barrel of the original factory 18-inch wheels. To run this specific GT kit safely, you need to step up to a high-quality 19-inch wheel setup or use specialized, high-clearance 18-inch track-spec wheels that provide extra internal barrel room.

Can I install this kit if my 996 Turbo came from the factory with yellow PCCB ceramic brakes?

No, this part number (1L3.9005A2) is built specifically for 996 Turbo models that came equipped with standard factory iron brakes. The steering knuckle mounting depths and hydraulic volume calibration on factory ceramic (PCCB) cars differ from the standard iron-brake models. If your car has factory yellow ceramic calipers, you will need a different Brembo catalog number configured specifically for the PCCB master cylinder bias and uprights.

Do these 2-piece floating rotors rattle loudly when driving over bumpy street roads?

No, they are remarkably quiet. While older, full-race floating rotors rattle loudly because of loose clearance tolerances, Brembo fixes this issue for street cars by utilizing custom anti-rattle spring clips inside their floating D-bobbin assembly. This spring layout keeps enough tension on the components to stop clicking and rattling over street bumps, while still allowing the outer iron ring to expand outwardly when it gets incredibly hot on the track.

⚠️ Note: Verify wheel clearance using Brembo's brake profile cross-section guide before purchasing. Also available in black (1L3.9005A1), silver (1L3.9005A3), and yellow (1L3.9005A5) caliper finishes.
