3. Remove the master cylinder cap (item 23) using a 26mm spanner.
4. Place the closed end of an 8mm spanner over the bleed nipple on the brake
caliper. Fit a length of clear plastic hose (approximately 30cm) onto the bleed
nipple and place the free end into an empty container. The hose should be a snug
fit and not fall off, the free end does not need to be submerged under brake fluid.
5. Fill the master cylinder reservoir with brake fluid.
6. Open the bleed nipple a 1/4 turn. Slowly pull the brake lever to the handle bars and
hold. Close the bleed nipple. Release the lever. Caution, squeezing the lever too
fast will cause brake fluid to squirt out of the master cylinder.
7. Repeat step 6 until no air is seen coming out of the bleed nipple. You will need to
keep refilling the reservoir during this operation. Caution, if bleeding a rear brake
be careful not to spill brake fluid onto the front
caliper and disc.
8. Unscrew the reservoir piston from the master
cylinder cap. Note that this is a left hand thread,
see Figure 5 .
9. Place a rag around the master cylinder to catch
any spillage and fill the master cylinder to just
below the top surface.
10. Place the reservoir piston into the master cylinder
and allow the fluid to overflow. Gently push it down
until it rests on the ‘O’ ring seal and clean away the excess fluid.
11. Screw the silver adjuster into the piston (note, this is a left hand thread and is part
of the master cylinder cap) until the cap makes contact with the top of the master
cylinder. Press gently down on the cap and thread it clockwise until it is tight then
tighten with a 26mm spanner. Screw the thumbwheel of the adjuster (item 25) anti-
clockwise to the limit of its travel.
12. Open the bleed nipple a 1/4 turn to allow the pistons to retract into the caliper. The
pistons are spring loaded and should return on their own but may require manually
pressing back. Close the bleed nipple and remove the plastic hose. Caution, do
not over tighten the bleed nipple. Wipe away any spilt fluid from the caliper and
lever.
13. Replace the pads and insert the wheel.
14. Adjust the silver thumbwheel to obtain the desired lever travel.
15. Check the brake for correct function and that there are no any system leaks.
