Extreme Performance Drilled and Slotted; Right
Power Stop's Drilled, Slotted & Zinc Plated Rotors are a popular brake performance upgrade. The rounded slots sweep away gas and debris to provide smooth, safe braking while beveled drill holes keep those brake temperatures down when you need it most. To ensure long lasting performance, silver Zinc Dichromate plating is applied to help protect against rust & corrosion. With a direct OE fit and vane count, upgrading the looks and stopping power of your vehicle has never been easier than this direct bolt-on upgrade.
Features & Benefits:
Precision drill holes allow for maximum rotor cooling, keeping your brakes temperatures down during extreme operating conditions
Rounded slots help wipe away any gas or debris keeping a clear contact patch on the rotor surface for safe, smooth braking
Silver Zinc Dichromate plating is applied to help prevent rust & corrosion and look great behind your wheels
Reversed engineered from OEM samples using G3000 grade iron
Each rotor is carefully machined and mill-balanced for safe, smooth braking performance
Installation Tips
Always replace Brake Pads and inspect Calipers and Brake Hoses when installing new rotors
Suspend the caliper from the suspension using a Caliper Hanger to prevent damage to the brake hose
After removing the old rotor, clean the hub face with a Wire Brush to remove rust buildup and apply Copper Anti Seize to prevent future buildup. Rust or debris on the hub can cause rotor runout and lead to wheel vibration
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
