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
