4. To insert the piston into the cylinder by effort of fingers, without using any tools, and by means of a screw-driver accurately to insert an external edge of a protective cover into a cylinder pro-point.
5. To grease the pumping valve with fresh brake fluid and to screw it in the bracket case.


The bracket case as it should be, the return to removal is installed. Thus to wrap two directing fingers the moment of 25 N · m (2,5 kgfs · l), holding thus the directing finger with a key. After installation to pump over the brake which underwent repair (see subsection 10.15).
