Anti Rust Rear Brake Disc ECE R90 Auto Spare Parts

The core value of this product lies in its professional anti-rust technology, which significantly enhances the durability, aesthetics, and maintenance convenience of rear brake discs while ensuring compliance with the highest ECE R90 safety standards.

1. Core Technology: Implementation of the “Anti-Rust” Design

Surface Coating Technology: This is the most critical process. A high-temperature resistant rust-proof coating is applied to the non-friction surfaces of the brake disc—particularly the center hub (mounting surface) and the edges of the cooling vents. Typically gray or black in color, this coating effectively blocks moisture and salt, preventing rust in these areas.

Core Benefits Delivered:

Maintains Aesthetics: Prevents unsightly rust from compromising the visual quality of the vehicle's side profile.

Facilitates Removal: Prevents rust-induced seizing between the hub and wheel hub, making future brake disc replacement easier and reducing repair time and costs.

Ensures Functionality: Prevents rust buildup from interfering with the proper fit between the brake disc and related components.

2. Core Safety Certification: ECE R90

Performance Equivalence Guarantee: This certification ensures the rust-resistant brake disc matches all critical safety metrics—braking performance, mechanical strength, thermal fade resistance, and balance—exactly with OEM components. The “rust-resistant” feature is an added value achieved without compromising any safety performance.

System Compatibility: Guaranteed seamless integration with the vehicle's ABS, ESP, and rear electronic parking system.

3. Specific Design for Rear Brake Discs

Rear wheels require less braking force than front wheels, so their design prioritizes long-term corrosion resistance and compatibility with electronic parking motors. The rust-proof coating is specifically optimized for these requirements.
