Shimano GRX Brake Caliper BR-RX820 w/ Resin Pads
Shimano GRX BR-RX820 brake caliper - perfect braking performance on off-road adventures
The BR-RX820 is the optimal brake caliper for the GRX RX820 gravel groupset from Shimano. The hydraulic flat-mount model impresses with excellent brake control, improved modulation and faster conversion of inputs. It is built more compactly than its predecessor and has 10% more space for the brake pads, which reduces noise. The simple bleeding process via one-way bleeding is well known. The BR-RX820 is made of lightweight aluminium, has two brake pistons made of synthetic resin and a straight hose connection. It comes with organic pads with Ice-Tech cooling fins for heat dissipation. Of course, it is also compatible with sintered pads and can be combined with brake rotors from 140 to 180 mm.

Technology:
One Way BleedingOne 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.
