Shimano BR-MT520 + BL-MT501 Disc Brake J-Kit

Shimano BR-MT520 + BL-MT501 disc brake - sufficient brake power

The Shimano BR-MT520 + BL-MT501 disc brake has the brake power of 4 ceramic pistons and can therefore be used for All Mountain to Freeride applications. The brake calliper can be easily and properly serviced with One-Way bleeding. On the other hand, the brake lever with Servo Wave technology helps in the modulation of sufficient braking power. Thanks to the I-Spec II design, ergonomics in the cockpit can be improved and a shifter integrated to save space.

Technology:

Servo Wave
Shimano Servo Wave technology optimises the travel of your brake levers. During the braking process, the brake pads are guided quickly to the brake rotor with very short lever travel. The greater part of the lever travel is reserved for the actual braking force. In this way, you can apply your braking power in a more targeted manner and use it more effectively.

I-Spec II
I-Spec II describes a variant of the connection between the brake lever and the shift lever on MTB or, more precisely, flatbar gears from Shimano. This type of mount makes for a tidy cockpit as it reduces the number of clamps needed. On some models it is also possible to adjust the shift lever both horizontally and vertically in relation to the brake lever. Then there is 12 mm of adjustment travel in the longitudinal direction and/or up to 15° of rotation - for optimum ergonomic adaptation to your riding style, seat position and anatomy.

One-Way Bleeding
One Way Bleeding is a technique used on Shimano calipers that facilitates brake bleeding. The hose routing has been optimised so that no air bubbles remain in the brake calliper. In combination with the funnel, the brake can be bled cleanly and easily.

J-Kit
J-Kit is a simple line connection system for hydraulic brakes from Shimano, so that you can install your brakes quickly and easily. The brake hose does not come connected to the brake to facilitate routing of the hose in the frame. The brake hose is already filled with oil in the J-Kit and sealed with a thin membrane. There is a small pin in the J-Kit brake lever that pierces this diaphragm during assembly to allow oil to flow.
