Brembo Floating Discs — Premium Lightweight Performance for High-End Vehicles
Brembo Floating Discs are engineered for premium and high-performance vehicles requiring exceptional braking stability, reduced unsprung mass, and superior heat management. Derived directly from Brembo’s top-tier OE technology, this floating bi-material design ensures unmatched resistance to thermal deformation, enhanced comfort, and consistent braking performance even under demanding conditions.
1. Bi-Material Floating Construction
Aluminium Hat + Cast Iron Braking Surface
Brembo Floating Discs feature a lightweight aluminium hat connected to a special high-carbon cast iron braking ring. This design reduces disc weight by 15–30% compared to traditional one-piece discs of the same dimension.
Floating Fixing Bushes
The braking surface and hat are connected via precision-engineered fixing bushes.
Benefits of the floating system include:
- Elastic expansion between components under high thermal load
- Prevention of disc warping and crack formation
- Stable geometry and braking feel across temperature cycles
Technology Derived from OE Premium Models
Floating discs in the Brembo Aftermarket range originate directly from OE applications on some of the world’s most exclusive vehicles.
2. Performance & Thermal Stability
Reduced Unsprung Mass
By significantly lowering the disc’s unsprung weight, the system improves:
- Vehicle handling
- Steering precision
- Ride comfort
- Fuel consumption and emissions
Superior High-Temperature Resistance
The high-carbon cast iron surface ensures reliable performance in extreme thermal conditions, drastically minimizing permanent deformation—up to 70% lower compared to conventional integral discs.
Fade & Crack Resistance
The floating interface allows the braking ring to expand freely under heat stress, reducing the risk of:
- Thermal cracks
- Hot spots
- Friction fade
3. Comfort & Driving Feel
Enhanced Braking Modulation
The reduced mass and floating connection deliver a refined brake pedal feel and improved responsiveness, even during repeated hard braking.
Optimized NVH (Noise, Vibration, Harshness)
The bi-material structure contributes to smoother braking and reduced vibration, enhancing comfort on premium vehicles.
4. Material & Structural Advantages
Key Technical Features:
- High-carbon cast iron braking surface for superior thermal behavior
- Lightweight aluminium hat (or steel hat depending on design variant)
- Fixing bushes allowing elastic axial and radial movement
- Directional or pillar venting options
- Optional drilled/grooved patterns depending on model application
These combined features ensure top performance, mechanical strength, and reliable durability.
5. Product Range & OEM Connectivity

6. Key Benefits
- Up to 30% weight reduction for improved fuel efficiency and reduced emissions
- Better handling & comfort due to lower unsprung mass
- Superior fatigue resistance at high temperatures
- More stable friction performance under demanding driving
- Minimized risk of deformation thanks to floating bush system
- Premium OE-equivalent quality using advanced Brembo materials and manufacturing
7. Pad Pairing Recommendation
The optimal brake pads for Brembo Floating Discs are Brembo Prime Brake Pads.
These pads ensure:
- Balanced, reliable braking
- OE-level compatibility
- Consistent friction and comfort
- Long-lasting performance on premium disc systems
8. Usage Considerations
Why Floating Discs Use Two Separate Components?
To allow the braking ring and hat to expand independently under thermal stress—critical for preventing deformation and maintaining long-term braking performance.
Track Usage
Although used on many high-performance OE vehicles, Brembo Floating Discs are engineered for road use only, not for dedicated track driving.
