Brand: Performance Friction Corporation (PFC)
If you have to pump your brakes once or twice every corner because of a long brake pedal, your pads may be getting knocked back away from the rotors between braking zones. What a waste of time!
Knock-back springs are designed to keep just a relatively small amount of pressure pushing the caliper pistons out, reducing the need to re-set the brake pads before actually braking.
This kit from Performance Friction was designed for the PFC ZR95 caliper with 29mm and 32mm pistons (calipers with 36.5mm pistons use a different kit). The springs are designed to apply 3 1/2 pounds of pressure. Each set includes 6 springs, enough for one 6-piston ZR95 caliper.
