Lithium Baterie 16a 186x81x170mm 1.4kg

Restore the bite and safety of your braking system with the Official square rear caliper trim OTK. This original brake cup is a vital hydraulic spare part, specifically designed to ensure the perfect containment of the brake fluid under pressure around the pistons of your rear caliper.

As highlights the photo, this joint is distinguished by its square section. Unlike a simple round O-ring, the square profile offers a flat contact area and maximized against the piston wall and the internal housing of the caliper. This technical geometry allows the seal to deform slightly during the pressure on the pedal to accompany the movement of the piston, then to "recall" in place during the release. Designed in a high-end elastomer resistant to extreme temperatures and chemical aggressiveness of hydraulic fluids, this seal removes liquid leaks and prevents air from entering the circuit.
