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.
