Detailed Product Description

This disc brake caliper features a cast iron construction that balances durability and heat dissipation, essential for rear brake applications.

The included caliper slides allow for smooth movement and proper pad alignment, which contributes to even pad wear and consistent braking performance. The floating caliper design is engineered to self-adjust, ensuring proper contact with the rotor during braking.
