E-car Floating Grooved Brake Discs

Brake Discs Features

1. Floating structure design, adapting to thermal expansion of the disc during braking.

2. Grooved pattern on the disc surface, helping to discharge debris and water.

3. Direct-fit for E-car OEM braking systems, no modification needed; each unit checked for runout before leaving the factory.

4. Equipped with anti-corrosive coating to prevent rust during use.

5. Meets OEM specifications, matching E-car braking system requirements.

Brake Discs Benefits

1. Combined floating and grooved design improves heat dissipation, reducing brake fade.

2. Grooves keep brake pad surfaces clean, enhancing initial brake "bite" for stable braking response.

3. Anti-corrosive coating extends service life, suitable for different use environments.

4. Direct-fit design enables easy installation, avoiding post-installation noise or vibration.

5. Reduces brake pad wear, lowering the frequency of component replacement.
   
   

Tips：

1. The Floating Grooved Brake Disc for Electric Vehicles is a high-performance component representing the pinnacle of braking system technology. It combines two advanced designs—floating construction and grooved disc surface—specifically engineered to meet the demanding requirements of electric vehicles.

2. Handling Extreme Heat: Electric vehicles are heavy, generating significant kinetic energy during deceleration. The floating brake disc connects the friction ring (outer ring) and mounting hub (inner ring) via specialized floating alloy rivets, allowing the friction ring minor radial and axial thermal expansion space.

3. Eliminating Thermal Stress: During sustained intense braking that generates extreme temperatures, traditional monolithic brake discs warp and deform due to thermal stress, causing brake judder. The floating structure effectively absorbs thermal expansion stress, significantly reducing thermal deformation to ensure smooth braking with no abnormal pedal feel.

4. Ultimate Heat Resistance: By preventing deformation and facilitating efficient heat dissipation, its friction coefficient maintains remarkable stability even under extreme temperatures, providing ultimate safety assurance for track driving or continuous downhill mountain descents.

5. Scraping Effect: Radial grooves on the disc surface act like scrapers, continuously removing oxidation layers, water films, and brake dust from the pad surface to maintain optimal friction contact.

6. Enhanced Initial Response: Critical for electric vehicles. Energy recovery reduces mechanical braking frequency, making discs prone to rust. The grooved design ensures pads immediately contact the high-performance surface during emergency stops, eliminating rust-induced braking delays.

7. Gas Evacuation and Heat Dissipation: At high temperatures, brake pad material vaporizes, forming gas pockets between friction surfaces that degrade braking performance. The grooves rapidly expel these gases while increasing heat dissipation area.

8. Matching Heavy Vehicle Weight and High Torque: The astonishing weight and acceleration capabilities of electric sports cars or high-performance SUVs demand equally robust braking systems. Floating grooved discs represent one of the ultimate solutions to meet these demands.

9. Addressing Challenges from Energy Recovery: Resolves issues of corrosion and delayed brake response caused by reduced braking system usage frequency.

10. Must be paired with high-performance brake pads: To realize their full potential, high-performance brake pads must be installed. Ordinary brake pads cannot deliver their advantages.
