All Balls 18-9002 Rear Brake Caliper Piston Rebuild Kit

The All Balls 18-9002 Rear Caliper Piston Kit provides a premium stainless steel solution for rebuilding your brake caliper. Each kit contains all the pistons needed to completely rebuild one rear caliper, restoring proper brake function and performance.

Key Features:

• Precision machined from high grade 304 stainless steel for superior durability
• Stainless steel construction reduces thermal conductivity by up to 93% compared to aluminum pistons
• Eliminates common failure modes associated with OEM materials—no brittle plastic composites, no corrosion-prone chrome plated steel or aluminum
• Removes failure-prone ceramic inserts found on some KTM models
• Complete kit includes all pistons required to rebuild one caliper

This caliper piston kit is engineered to outperform stock components by addressing the weaknesses of OEM designs. Plastic composite pistons become brittle and crack with age and heat cycles, while chrome plated steel and aluminum pistons are susceptible to corrosion that can cause sticking and uneven brake pad wear. The 304 stainless steel construction provides exceptional corrosion resistance and maintains structural integrity across a wide temperature range, ensuring consistent brake performance and long service life.
