The Shimano BR-MT520 disc brake caliper is designed for use on both the front and rear of the bicycle. It features a powerful 4-piston design, with dual diameter pistons providing a larger contact area for the brake pads. This results in responsive braking power and enhanced control, making it particularly suitable for the high demands of e-bike riding, as well as mountain biking.

The master cylinder of this caliper is engineered for a sleek appearance and lasting durability. Metal brake pads are included, known for their longevity and excellent performance in wet and high-wear conditions, although they can be noisier than their resin counterparts.

As a post mount caliper, it attaches to the frame or fork at the mounting posts, which is a common fitment standard offering straightforward installation.

The caliper is designed to work with hydraulic brake lever systems and uses mineral oil as its hydraulic fluid. This type of fluid is preferred for its stable performance over time and its non-corrosive properties.

Please note that while this brake caliper is e-bike certified, indicating its suitability for the higher speeds and weights associated with e-bikes, the rotor is not included and should be chosen to match the specific needs of the rider and the bicycle.
