How does the assembly perform compared with original equipment?

The caliper and master cylinder are built to the manufacturer's specifications for fit, piston size and mounting so they deliver pressure and modulation close to the original design. Precision alloy pistons resist wear and help maintain braking force under normal riding conditions.

• Pre-assembled caliper with brake pads and banjos reduces install time.
• Exact mounting bracket design allows direct bolt-on replacement in compatible models.
• Alloy pistons and sealed components extend service life versus heavily worn originals.

What comes in the package and what do I need to install it?

The kit contains one rear brake caliper and one rear brake master cylinder, packaged securely for shipping. You’ll need basic hand tools, fresh brake fluid, and routine bleeding equipment; minor hardware reuse may be possible if it’s in good condition.

• Included: Rear Brake Caliper x1, Rear Brake Master Cylinder x1, brake pads and banjos in a protective box.
