The BR-MT520 4-Piston Disc Brake is Shimano's entry level 4 pot brake, but that doesn't mean its lacking in power. Featuring the highly responsive braking we have come to love from Shimano. They come with heat insulated pads and pistons for improved heat management and improved modulation from their sleek looking 4 piston design. These are an excellent choice for a wide range of applications.
