1. Drain the working fluid first. To do this, put one end of the hose on the air outlet 9 of the working cylinder (see fig. Slave cylinder and clutch release fork), and lower the other into a clean vessel, unscrew fitting 9 by 1/2–3/4 turn and press the pedal until the liquid is removed from the hydraulic system, then disconnect the tubes connecting the main and working cylinders, disconnect the release spring 7, remove the cotter pin from the end of the pusher, and then the working cylinder by unscrewing the two mounting bolts.
2. To remove the master cylinder, unscrew the two nuts with which it is studded to the pedal bracket and disconnect the reservoir flexible hose.
3. To install the master and slave cylinders, perform the above operations in reverse order.
4. After refueling with working fluid, pump the hydraulic drive.
