All Balls Brake Caliper Piston Rebuild Kit Stainless Steel

The All Balls Brake Caliper Piston Kit is a stainless steel replacement piston (caliper piston) for rebuilding or restoring motorcycle, off-road and powersports brake calipers. Each piston is precision machined from high-grade 304 stainless steel. It is a durable upgrade over worn, corroded or damaged factory pistons.

Key Features:

• Precision machined from high-grade 304 stainless steel
• Stainless steel reduces thermal conductivity versus aluminum pistons, which helps keep heat away from the brake fluid and supports consistent braking during hard use
• Resists the corrosion that can affect OEM chrome-plated steel and aluminum pistons
• Stays durable where plastic composite pistons can become brittle and damaged with age
• Eliminates the failure-prone ceramic inserts found on some KTM models
• Each kit contains the piston or pistons needed to rebuild one caliper

Pair with a matching All Balls caliper rebuild kit (seals, boots and hardware) for a complete caliper refresh. The result is smooth piston travel and reliable braking performance.
