Removal and installation of the working and master cylinders of the clutch drive (VAZ-2121)

First of all, drain the working fluid. To do this, put one end of the hose on the air release nipple 9 (fig. 3-3) of the working cylinder, and lower the other into a clean vessel; unscrew the nipple 9 by 1/2-3/4 of a turn and press the pedal until the fluid 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, unscrewing the two mounting bolts

To remove the master cylinder, unscrew the two nuts that secure it to the studs on the pedal bracket and disconnect the flexible hose from the reservoir.

To install the master and slave cylinders, perform the above operations in reverse order.

After filling with working fluid, bleed the hydraulic drive.
