Description

The Shimano XT M8000 disc brake caliper is a part of Shimano's XT range, which is renowned for balancing the demands of performance and durability for serious mountain biking. This caliper is versatile enough to be mounted on either the front or the rear wheel, designed to offer dependable braking power in a lightweight package.

This caliper is compatible with Shimano's Ice Technology finned pads, which are not included but can be fitted to improve heat dissipation during long or aggressive descents. The caliper features one-way bleeding, which simplifies the process of purging air from the system, making installation and maintenance more straightforward.

The inclusion of ceramic pistons in the design is a key aspect of its improved heat dissipation capabilities, which ensures consistent braking performance even under high thermal stress. Although the caliper comes with resin brake pads, which are known for their quieter and more progressive braking feel, it is also compatible with metal pads for those seeking longer pad life and better performance in wet and abrasive conditions.

As a post-mount caliper, it can be directly bolted to the frame or fork's designated posts. The system utilizes mineral oil hydraulic fluid, which is less corrosive than some alternatives and maintains consistent performance across a variety of temperatures.
