9. Use pliers to open the spring clamp of the brake fluid reservoir hose and slide it up the hose.
10. Remove the hose from the cylinder fitting.
11. Using pliers with narrow jaws, remove the spring of the brake signal sensor, first from the pedal, and then from the sensor itself.

Installation
1. We assemble in the reverse order.
2. The position of the rod tip must be adjusted so that the distance between the centers of the hole on the tip and the lower mounting hole of the cylinder is 67.5 mm.
3. When installing the stem end pin, it is recommended to install a new cotter pin to replace the used one.
4. When reinstalling the brake hose, use new copper or aluminum sealing washers (in the photo are marked with arrows).
Attention! The sealing washers of the brake hose fittings must not be reused. New washers must be installed with each assembly.
5. Tighten the brake hose fitting bolt to 35 Nm.
6. After installing the footrest bracket with the brake cylinder on the motorcycle, by turning the plastic nut, we adjust the correct position of the brake signal sensor. The brake signal should turn on after 3-5 mm of brake pedal travel.
7. After installing all the brake mechanisms, we pump the rear brake circuit (see «Hydraulic brake drive - brake fluid replacement and pumping»).
