Product Overview

CORINTH front and rear brake rotor kits provide a convenient, complete solution for full vehicle brake service, containing all rotors needed for both front and rear axles in a single matched package. Each kit is assembled with rotors manufactured to the same quality standards and OE specifications, ensuring consistent braking performance across all four wheels and simplifying procurement for repair shops and vehicle owners.

Core Kit Advantages

· Complete Axle Coverage: Each kit includes 2 front rotors and 2 rear rotors (4 total), covering all braking positions on the vehicle. This eliminates the need to order front and rear sets separately, reduces shipping costs, simplifies parts lookup and ensures all rotors are replaced at the same time for balanced braking performance.

· Matched Quality & Dimensions: Front and rear rotors in each kit are manufactured to the same quality standards and precision-machined to exact OE specifications for the target vehicle. This ensures proper fitment with factory calipers, hubs, parking brake systems and wheel assemblies, and maintains the vehicle's engineered front-to-rear brake balance.

· Consistent Coating & Finish: All rotors in the kit receive the same anti-corrosion coating and surface finish, ensuring uniform appearance across all four wheel positions — particularly important for vehicles with open-spoke alloy wheels where rotors are visible. Consistent coating also provides equal corrosion protection for all positions.

· Balanced & Quality Verified: Every rotor undergoes individual dynamic balancing, and kits are assembled with matched quality across all four positions. This provides consistent, smooth braking performance with no vibration or judder after service, and ensures the vehicle brakes straight and true with even pad wear across all axles.

Kit Contents & Usage

· Standard Kit Contents: 2 front brake rotors (vented per OE spec) + 2 rear brake rotors (solid or vented per OE spec) + axle-position labeling + installation guidance.

· Suitable For: Repair shops, fast-fit chains, mobile mechanics and vehicle owners performing complete brake rotor service. Pair with matching front and rear brake pad sets for full brake service.

· Expected Service Life: 50,000–70,000 km under normal driving conditions. Front rotors typically wear faster than rear rotors within the kit.

· Installation: Direct bolt-on replacement for all four positions. Follow proper bedding-in procedure after installation. Verify parking brake function for rear rotors with integrated drum.

Quality Assurance & Certification

Manufactured under IATF 16949 quality management with 100% dimensional inspection and dynamic balancing for every rotor in the kit. ECE R90 certification available for applicable models. Kits are packaged with clear axle-position labeling to prevent installation errors. Full cross-reference data and application support provided for wholesale and repair shop partners. Custom kit configurations available for OEM and private label customers.
