Restore reliable brake caliper performance with the All Balls Brake Caliper Piston Kit, manufacturer part number 18-9035 and vendor part number 21-89035. This replacement kit is precision machined from high-grade 304 stainless steel to provide dependable durability and corrosion resistance during demanding powersports use. The stainless steel construction helps reduce thermal conductivity by up to 93% compared with aluminum, supporting consistent caliper operation under braking conditions.
The All Balls 18-9035 kit is designed to replace failure-prone original caliper pistons, including plastic composite pistons that can become brittle with age, as well as chrome-plated steel and aluminum pistons that may be vulnerable to corrosion. The kit also eliminates the ceramic inserts found in some KTM applications. Each kit includes the piston or pistons required to rebuild one brake caliper, helping simplify service and restore proper fit and function.
