2. Remove the protective rubber boot of the brake caliper bleeder and put on the fitting an elastic transparent hose of suitable diameter, the other end of which is lowered into a clean container filled with fresh brake fluid (see «Hydraulic brake drive - brake fluid replacement and pumping»).
3. Press the brake lever 3-5 times and keep it pressed.
4. We loosen the bleed valve by unscrewing it with a key of 8 mm by 0.5-1.5 turns. At the same time, the lever begins to move. displacing the brake fluid through the hose.
5. After the lever has moved all the way, tighten the fitting, then release the brake lever.
Attention! Do not allow the tank to empty, otherwise the pumping will have to be done again.
6. Repeat the pumping operations until air bubbles disappear from the brake fluid coming out of the hose. Periodically check the fluid level, top up when the level drops. When bleeding a dual disc front brake, repeat the operation for the second caliper.
7. Add brake fluid to the upper mark in the reservoir sight glass, install the membrane, membrane plate and reservoir cap. We wrap two screws of the cover, wipe the leaks of brake fluid with a rag (see «Hydraulic brake drive - brake fluid replacement and pumping»).
Bleeding the hydraulic drive of the rear brake is carried out in the same way.
