Features & Benefits:
  • Formulated with steel strands to provide strength and conduct heat away from the rotor's surface while offering premium braking power
  • Premium shims, slots, and chamfers help to diminish noise, vibration, and braking harshness
  • Ready to be installed right out of the box – no curing required
  • Tested to SAE J2784 for braking effectiveness, along with Noise/Vibration/Harshness (NVH) and durability/wear testing for quality
  • Friction material is integrally molded to the backing plate for bond integrity
  • Stamped backing plate allows for proper pad movement within the caliper assembly, helping to minimize noise, brake pulsation, and helping to protect against premature wear
Organic vs. Ceramic vs. Semi-Metallic - What Is The Difference?

A common question many drivers have when shopping for brake pads is “What is the difference between the different brake pad materials?” While all brake pads will stop your vehicle, there are pros and cons of each pad material:

Installation Tips
  • Suspend the caliper from the suspension using a Caliper Hanger to prevent damage to the brake hose
  • Apply Brake Lube to caliper pins, clips, the edges of the brake pad mounting tabs, and the back side of the brake pads to ensure noise free braking. DO NOT apply lube to the friction side of the brake pads
  • Use a Caliper Piston Compressor to retract the caliper piston(s) and make room for the new, thicker brake pads
  • Open the master cylinder reservoir during piston compression to prevent pressure buildup. Keep an eye on the Brake Fluid level to ensure it does not overflow
  • After the job is complete, pump the brake pedal several times to push the caliper piston back up against the pads to ensure proper brake function
