All Balls 18-9003 Rear Brake Caliper Piston Rebuild Kit

The All Balls 18-9003 Rear Caliper Piston Rebuild Kit delivers superior performance and durability for your motorcycle's braking system. This precision-engineered replacement kit is designed to restore your rear brake caliper to optimal performance while offering significant advantages over OEM components.

Premium Stainless Steel Construction:

• Far more durable than plastic composite pistons that become brittle and prone to cracking over time

Performance Benefits:

• Eliminates failure-prone ceramic inserts found on select KTM models
• Maintains consistent brake performance by resisting heat-related fluid degradation
• Long-lasting construction reduces the need for frequent replacements

Each kit contains the piston or pistons needed to rebuild one rear brake caliper. All Balls Racing Products are trusted by professional mechanics and enthusiasts alike for quality brake system components that meet or exceed OEM specifications.
