1. Disconnect the wire from the negative terminal of the battery.
2. Unscrew the cap of the brake master cylinder reservoir...
3. ...and pump out the brake fluid from the reservoir, for example, using a large medical syringe.
4. Remove the brake fluid level sensor from the reservoir...
5. ... squeeze the clamps, disconnect the wiring harness connector from the brake fluid level sensor adapter connector.
6. Disconnect the wiring harness from the brake cylinder reservoir bracket.
7. Remove the screw securing the reservoir to the master brake cylinder...
8. ...and remove the screw.
9. Disconnect the clutch release cylinder hose from the master cylinder reservoir.
Helpful Hint: Immediately after disconnecting the clutch hydraulic hose from the reservoir, plug its opening or pinch the hose without lowering it down. There will be some working fluid left in the hose, so after installing the reservoir and connecting the hose to it, there is no need to bleed air from the clutch hydraulic drive.
10. Pull up and remove the tank, removing its pipes from the connecting bushings.
11. Remove the connecting bushings from the cylinder body holes. Reusing the connecting bushings is not allowed, replace them with new ones.
12. Before installing the reservoir, insert connecting sleeves 3 and 4 into the opening of the master brake cylinder (Fig. 9.7). Then install the reservoir by inserting its pipes into connecting sleeves 3 and 4 by hand until they stop, and secure with a screw.
Fig. 9.7. Master brake cylinder: 1 - piston pusher; 2 - cylinder mounting flange; 3, 4 - connecting bushings; 5 - brake cylinder housing; 6, 7 - connecting holes of pipelines; 8 - hole for the tank mounting bolt; 9 - rubber sealing ring
Helpful Hint: To make installation of the reservoir easier, wet the connecting bushings with fresh brake fluid.
13. Fill with brake fluid and bleed air from the hydraulic drive (see "Replacing brake fluid").
