Product Overview

CORINTH rear axle brake discs are engineered to match original equipment specifications for rear wheel installation, available in both solid and vented configurations depending on the vehicle application. These rotors provide consistent rear braking performance, working in harmony with the front brakes to maintain the vehicle's engineered brake balance and stability.

Core Rear Axle Advantages

· OE-Matched Solid or Vented Configuration: Rear rotors are available in solid configuration (for compact and economy vehicles) and vented configuration (for larger, heavier or higher-performance vehicles), matching the original equipment specification for each application. Using the correct configuration ensures proper brake balance and thermal performance.

· Exact Rear Dimensional Specifications: Each rear rotor is precision machined to OE dimensions including diameter, thickness, bolt pattern, hub height, seat type and integrated parking brake drum (where the vehicle uses a drum-in-hat parking brake design). This ensures direct fitment with rear calipers, parking brake mechanisms and wheel hubs.

· G3000 Cast Iron Quality: Constructed from reliable G3000 gray cast iron delivering consistent friction performance and durability for rear axle braking duty. The material provides adequate thermal capacity for the lower braking loads typical of rear axle operation under normal driving conditions.

· Anti-Rust Coated & Balanced: Protective coating on non-friction surfaces prevents corrosion, which is particularly important for rear rotors that may be used less frequently and are more prone to surface rust from low usage. Dynamic balancing ensures smooth, vibration-free rear braking without pedal pulsation.

Application & Usage

· Suitable Vehicle Types: All passenger cars, sedans, hatchbacks, SUVs, vans and light trucks requiring rear axle brake disc replacement.

· Operating Conditions: Normal daily driving conditions. Rear brakes handle approximately 30% of braking force, operating at lower temperatures than front brakes.

· Expected Service Life: 60,000–80,000 km under normal driving conditions. Rear rotors typically last longer than front rotors due to lower braking load.

· Installation Notes: Direct OE replacement. Verify solid vs. vented specification before ordering. For vehicles with integrated parking brake, ensure parking brake shoe compatibility and adjustment after installation. Always replace in axle pairs.
