Product Details

DFC designed this brake service kit to bring the rotor, pad, and hardware components together in one package for a front and rear brake job. The GEOSPEC coated rotors are machined to tight tolerances, inspected for critical dimensions, and finished to support smooth braking performance. The 5000 Advanced ceramic pads are formulated for consistent friction, while the included hardware is engineered to restore proper spring tension and caliper movement where worn or corroded parts can create noise and uneven wear. This part number, 4514-48027, is a practical choice for drivers servicing a GMC Envoy or Chevrolet Trailblazer brake system with OE-style replacement components.

Verify the exact axle application before ordering, since this kit is listed for front and rear use on the vehicles shown.
