Brake Disc for CHEVROLET Rear ECE R90

Custom-engineered for Citroën, Mitsubishi, and Peugeot rear brake systems, precisely tailored for flagship models including Citroën C5, C6, C5 Aircross; Mitsubishi Outlander, ASX; and Peugeot 508, 4008. Manufactured in strict compliance with the original equipment (OE) technical specifications of the three major brands, the mounting holes, positioning benchmarks, and dimensional parameters perfectly match the rear brake calipers. Installation requires no modifications and is compatible with the vehicle's ABS/ESP electronic brake control systems, providing a highly adaptable solution for aftermarket maintenance and replacement.

ECE R90 Certified for Controllable Rear Braking Performance

Products carry ECE R90 EU safety certification. Core components utilize high-strength gray cast iron substrates treated with carbonitriding surface hardening, forming a dense, wear-resistant layer 0.05-0.08mm thick. Friction coefficients remain stable within the 0.38-0.42 range. Disc rigidity is specifically optimized for rear brake system coordination, enabling precise force distribution with front brakes. During high-speed emergency stops or prolonged downhill braking, heat fade suppression exceeds 30%, ensuring linear and controllable braking performance.

Specialized Process Optimization Balancing Durability and Quietness

The rotor features a spiral ventilation groove design, increasing ventilation cross-sectional area by 25% compared to traditional straight grooves for significantly enhanced heat dissipation. The surface undergoes dual-layer electrophoretic anti-corrosion treatment, passing 500 hours of neutral salt spray testing without corrosion traces, resisting erosion in humid and saline environments. Precision-machined in ISO 14644-1 Class 7 cleanrooms, dynamic balance error is controlled within 5g·cm. Combined with integrated damping pads on the backing plate, brake squeal occurrence is reduced by over 90%, achieving service life equivalent to OEM components.

Comprehensive Scenario Compatibility & Robust After-Sales Support

Suitable for diverse scenarios including luxury business commuting, daily family travel, and long-distance self-driving. Balances Citroën's comfort positioning, Mitsubishi's off-road adaptability, and Peugeot's handling characteristics.

Product Core Advantages

1. Slotted surface design for high‑intensity braking scenarios

   Specially engineered slot grooves run across the friction surface. When braking, slots swiftly evacuate brake dust, gas residues and fine debris generated between disc and pads. It avoids gas‑fading effect, maintains stable friction coefficient under repeated hard braking, ideal for heavy‑duty daily driving, mountain‑road descent and occasional spirited driving.

2. Custom‑graded cast‑iron material matrix

   We deploy multiple cast‑iron formulations: grey iron, high‑carbon, G3000, GG15HC, DIN and SAE grade. High‑carbon variants deliver superior thermal conductivity and crack‑resistance under heavy load. Buyers can pick material grade balancing cost, strength and thermal performance for passenger cars, SUVs and light‑load vehicles.

3. Full certification for global aftermarket access

   Validated to IATF‑16949, ISO14001, ISO45001, ECE R90 and AMECA standards. Third‑party lab tests cover thermal shock, burst strength and dimensional stability. Complete certification documents support customs clearance across global markets and lower compliance risks for overseas distributors.

4. Precision turning + grinding process for consistent geometry

   After rough turning for base profile, fine grinding guarantees flatness, parallelism and tight run‑out tolerance. Even with slotted modification, disc flatness stays well‑controlled, minimizing steering shudder, pedal vibration and abnormal noise during deceleration, perfectly matched with OE caliper assemblies.

5. Multiple anti‑corrosion solutions for cross‑ocean logistics

   Anti‑rust oil immersion, paint finish, protective coating and zinc‑dust treatment are optional. Surface protection fights rust risk during long sea shipment, damp warehouse storage and wet‑climate road use. You can select treatment matching target‑market climate and inventory turnover cycle.

6. Diversified visual finishes for private‑label differentiation

   Available in grey, black, bare metallic and gold surface treatments. The slotted appearance itself has strong visual impact, helping retailers build performance‑oriented product lines and attract consumers chasing both braking capability and aesthetic look.

7. OE‑equivalent mounting dimensions for direct replacement

   Mounting face, bolt hole layout and overall dimensions strictly follow original equipment specifications. No modification required for installation at repair shops, enabling direct swap for target vehicle models.

Material & Production Workflow

Material Specifications

‑ Cast blank: Grey Iron / High‑Carbon Cast Iron (G3000, GG15HC, DIN, SAE grade). Compact metallographic structure brings outstanding vibration damping, wear resistance and heat conduction, lowering squeal tendency. 

‑ Anti‑rust options: Oiled, painted, coated, zinc‑dust treatment 

‑ Surface appearance: Grey, black, bare metal, gold

Manufacturing Steps

1. Melting & ingredient tuning: Raw iron molten, chemical composition adjusted to reach target grade requirements.

2. Precision casting: Form disc blanks; strict quality control to eliminate internal defects like shrinkage cavities and porosity.

3. Stress‑relief annealing: Heat treatment removes residual casting stress to resist thermal deformation under heavy braking.

4. Blank screening: Visual inspection plus non‑destructive testing reject defective blanks before machining.

5. Turning: Rough & finish turning shapes hub mounting surface, outer circle and inner structure.

6. Slot cutting: Precision milling forms performance slots on friction surface.

7. Double‑sided grinding: Fine grinding ensures parallelism and uniform thickness.

8. Hole processing: Bolt holes and locating holes machined per OE drawings.

9. Anti‑rust finishing: Apply customer‑specified anti‑corrosion treatment.

10. Final quality control: Run‑out detection, dimensional check, appearance inspection; sampling test for certification compliance.

Packaging Solutions

‑ Single‑unit protection: Protective wrapping film to prevent scratches and impact damage. 

‑ Custom retail carton: Support private‑label custom printing, mark OE number and vehicle fitment info. 

‑ Outer shipping package: Box, carton, palletized loading or bulk shipment. Export‑grade heavy‑duty packaging fits long‑haul sea freight and mixed container loading.
