NISSIN Rear Brake Caliper Piston Kit (Manufacturer part number: SRPK-003) — a simple and reliable replacement component for refurbishing the rear caliper. This kit provides the necessary piston(s) for the specific application to restore the braking component without improvisation.
Designed for off-road and motocross motorcycles, this kit integrates during a caliper service to replace a worn, corroded, or scored piston. Replacing the piston prevents sealing issues and local caliper blockages; it is part of the routine maintenance operations when changing pads or performing a complete refurbishment. The kit includes the application-specific piston(s), ready to be installed by a qualified mechanic or in a workshop.
Be sure to check the condition of the seals and fluid lines during the intervention, and to follow the torque specifications and bleeding procedures recommended by your motorcycle manufacturer. This kit is particularly suitable for the SUZUKI DR-Z 250 series of the indicated model years, among other compatible models.
