6. When installing, fill the cylinder with fluid – this measure significantly reduces the time it takes to bleed the brakes. Clamp the cylinder in a vice by the flange, pour fluid into the reservoir and press on the piston with a large Phillips screwdriver. When releasing the piston, clamp the holes of the fittings with your fingers. After pressing on the piston several times, close the holes with plugs.
7. Install the cylinder in reverse order. Remove air from the hydraulic drive.
