Installation Notes

Verify the rear brake shoe size, axle type, brake package codes, and GVW details before ordering. This kit is application-specific for front service, so matching the exact configuration listed for your Chevrolet or GMC model is important for proper fitment. Part number 4202-48038 should be checked against the vehicle’s brake setup before installation.

Quality Assurance

Use this kit as a catalog-matched replacement for the listed front brake applications. The coated rotor surface is intended to help reduce visible corrosion on non-friction areas during normal service conditions.
