Brake Disc for CHEVROLET, OPEL, VAUXHALL Rear ECE R90

This front brake disc is designed for Chevrolet, Opel, and Vauxhall models and meets ECE R90 standards.

Its core value lies in the seamless integration of “platform-based high compatibility” and “front-wheel high-performance braking requirements.” Below is a clear analysis of key technical points:

1. Core Feature: Cross-Brand Compatibility

This front brake disc fits three brands simultaneously, rooted in General Motors' global platform strategy (e.g., Delta, Epsilon platforms). This means models developed on the same platform but under different brands (e.g., Opel Astra/Insignia, Chevrolet Cruze/Malibu) share identical front axle brake system specifications. This offers significant procurement convenience and inventory optimization for repair shops and vehicle owners.

2. Technical Highlights: Materials, Manufacturing, and Certifications (Focus on Front-Wheel Performance)

Materials and Structure: As the component bearing the majority of the vehicle's braking force, the front brake disc must be a ventilated disc. Typically crafted from high-carbon alloy cast iron, it offers superior mechanical strength and resistance to thermal cracking to withstand the extreme heat and stress generated during braking.

Core Performance: The primary function of front discs is efficient heat dissipation and resistance to thermal fade. Their optimized internal ventilation channels rapidly expel heat, ensuring stable braking performance during sustained applications like high-speed deceleration or mountain driving.

Safety Certification (Core): ECE R90 certification is a mandatory safety requirement. It guarantees that this brake disc is fully equivalent to OEM parts in critical performance aspects like braking efficiency, heat resistance, and mechanical strength, while also ensuring seamless integration with the vehicle's electronic systems like ABS and ESC.

Processing: May include rust-proof coating (on the hub area), but the front disc places greater emphasis on high-speed dynamic balancing to prevent steering wheel vibration during high-speed braking.

At the same time ,this brake disc can fit all three brands simultaneously, rooted in General Motors' global platform strategy (such as the early Gamma platform and subsequent shared architectures). This means chassis components like rear brake discs share identical specifications across models developed on the same platform but under different brands (e.g., Opel Astra and Chevrolet Cruze). This offers significant procurement convenience and inventory optimization potential for repair shops and vehicle owners.

This product covers the following Chevrolet, Opel, and Vauxhall models on the rear axle (specific fitment depends on model year and brake system configuration):

Note: Different engine outputs and brake system grades within the same model may use different rear disc sizes. The above list shows common correspondences – final confirmation must be based on the OE number on the original disc or measurements.

The rear disc friction band width (the annular friction area width on the disc face) must match the rear pad friction material width. This product is manufactured to original specifications – its friction band width is consistent with the original rear pad dimensions of the corresponding vehicle. If the friction band width does not match pad width: 1。Friction band too wide – the pad cannot cover the entire friction surface – un-contacted areas rust and generate noise during subsequent braking; 2.Friction band too narrow – part of the pad friction material overhangs – generating uneven wear. When replacing discs, if replacing pads simultaneously, choose pads with the same width specification as the original pads.

Dimensions Match Original: Outer diameter, thickness, centre bore, PCD, offset all manufactured to platform specifications – direct replacement with no modification.

Clear Wear Marking: Disc laser-engraved with minimum thickness value – providing a reliable replacement decision reference.
