Product Details

DFC’s 5000 Advanced Brake Pads are formulated for modern vehicle braking demands and are built with post-curing and scorching processes that help deliver consistent friction from the first stop. The pads are assembled with premium shims to reduce brake noise and harshness. The GEOSPEC coated rotors are engineered to OE specifications, machined to tight tolerances, and finished to promote even pad contact and smoother stopping. This front brake kit is a practical choice for drivers servicing a Chevrolet Trailblazer, GMC Envoy, Isuzu Ascender, or Buick Rainier with front brake wear concerns. Part number 4512-48131 is also identified as a DFC GEOSPEC coated rotor and 5000 Advanced pad kit for front axle service.

Common Issues This Kit Can Address

• Front brake pulsation from worn or uneven rotors
• Brake noise caused by fatigued or corroded hardware
• Reduced stopping performance from worn pads
• Rust buildup on exposed rotor surfaces
• Uneven pad wear from aged brake hardware
