NISSIN Rear Brake Caliper Piston Kit (manufacturer part number RP-009): a set designed for the refurbishment of rear calipers on dirt bikes. This kit provides all the necessary pistons to replace worn, marked, or corroded components, restoring a caliper ready to receive seals and reassembly. Manufactured by NISSIN, a specialist in running gear and braking components, it is aimed at track mechanics and demanding DIYers who are renewing their brakes.
Before installation, check the condition of the seals and the seating in the caliper and perform a thorough cleaning/degreasing. This kit allows for the restoration of the moving part of the caliper; remember to bleed the system after reassembly to ensure reliable braking. Check compatibility with your machine — among the common applications: Honda CR 85 R (HE07) 2007 85 cc, CR 85 R Big Wheels (HE07) 2007 85 cc, and CR 80 R (HE04) 2002 80 cc.
