Shimano CUES BR-U8020 Disc Brake w/ Resin Pad J-Kit

Shimano CUES BR-U8020 disc brake with resin pads - Four-piston model for touring and city traffic

This Shimano disc brake from the CUES series for touring and city bike use consists of the BR-U8020 4-piston brake caliper and the BL-U8000 brake lever with 3-finger lever. It comes with organic cooling fin brake pads included.
The BR-U8020 caliper provides reliable, finely adjustable brake control and delivers even more braking force than the two-piston version. You benefit from this especially on fast rides and downhill runs. It is made of painted aluminium and has a banjo connection for the brake hose. The brake pistons are made of heat-resistant ceramic. Thanks to the One-Way Bleeding technology, the bleeding process can be carried out cleanly, quickly and easily.
The BL-U8000 brake lever was also designed for excellently dosed, powerful braking. Ergonomics and operating comfort have been improved by moving the brake lever joint closer to the handlebars. It has a clamp that allows for the integrated mounting of a CUES I-Spec II shifter, which saves space and opens up further customisation options. The handle consists almost entirely of lightweight aluminium and is adjustable in width without tools.

Technology:

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.

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.

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.
