PV Floating Steel Hat Brake Discs

Brake Discs Features

• Equivalent to OE design for precise vehicle fitment.

• Floating structure with steel hat and high-carbon friction ring, allowing thermal expansion during braking.

• Anti-rust coating on non-friction surfaces for corrosion resistance.

• Compliant with ECE R90, GB/T 34422 (national auto brake disc standard), and IATF 16949 certifications.

• Optimized thermal performance to reduce brake fade under heavy use.

Brake Discs Benefits

• Smooth and quick braking response with consistent performance.

• Low noise and low brake dust during operation.

• Extended service life via durable materials and anti-rust design.

• Efficient heat dissipation to maintain braking stability in intense scenarios (e.g., high-speed or heavy-load braking).

• Floating design minimizes warping and ensures even brake pad contact, enhancing overall braking control.

PV: This is typically a friction material grade designation used by high-performance brake pad or brake system manufacturers (e.g., from well-known brands like Performance Friction). The “P” may stand for Performance, while the “V” could correspond to a specific high-temperature or track-specific formulation. It signifies that this brake rotor is designed and tested to match competition-grade brake pads capable of withstanding extremely high temperatures.

1. Passenger Vehicle Coverage: Sedans, SUVs, Crossovers & Hatchbacks

Our catalog covers a wide range of passenger vehicles including sedans, SUVs, crossovers, hatchbacks, and wagons from major global brands — ensuring the correct floating steel hat brake disc for every popular passenger vehicle application. Each part number is cross-referenced against OE numbers for guaranteed fitment.

2. Floating Steel Hat Design: Thermal Expansion & Durability

These passenger vehicle brake discs feature a floating steel hat design that allows independent thermal expansion between the hub and friction ring — preventing warping and cracking under heavy braking while maintaining structural rigidity. The steel hat provides superior durability and corrosion resistance compared to aluminum alternatives, ensuring long service life for daily driving applications.

3. Two-Piece Construction: Weight Reduction & Heat Dissipation

Engineered with a two-piece floating construction, these brake discs separate the steel hat from the high-carbon cast iron friction ring — reducing overall disc weight by up to 15% compared to traditional one-piece cast iron discs. The floating design improves heat dissipation, reduces unsprung mass for enhanced suspension response, and allows for independent replacement of the friction ring when worn.

4. High-Carbon Friction Ring: Consistent Braking for Daily Driving

These floating steel hat brake discs feature a high-carbon cast iron friction ring that provides superior thermal conductivity, consistent friction characteristics, and enhanced wear resistance — ideal for daily passenger vehicle driving. The high-carbon material reduces brake fade, resists thermal cracking, and delivers smooth, predictable braking performance in all driving conditions, from city commuting to highway cruising.
