1. Loosen the adjusting ring (d) counterclockwise;
2. Unscrew the cylinder closure knob (e), slightly press the brake pedal to take out the
rubbers (c) and washers (b)；
3.
Dip an appropriate amount of lubricating oil with a cotton swab, apply it to the two
ends of the new rubber to be replaced and its edges, and seal both ends of the rubber
with gaskets of the corresponding size. The washer and the rubber are adhered to
each other by the viscosity of the lubricating oil, and put the two washers and one
rubber into the cylinder as a whole(g)；
4. After properly fitting the rubbers (c) and washers (b), install the cylinder closure
knob (e) and adjusting ring (d)；
5. Turn the adjusting ring (d) clockwise to increase the initial stiffness and shorten the
pedal travel range; turn the adjusting ring (d) counterclockwise to decrease the initial
stiffness and increase the pedal travel range.
