  • Set of Allen keys
  • Open-end and ring spanners 8 + 10
  • Phillips head screwdriver
  • Bottle with clear plastic tube that fits well on the bleed-valves
  • Brake-fluid DOT 4
  • Cloth (used to protect the work-space from the agressive brake-fluid)

Front Brake

Undo the retaining screws and remove the right master cylinder reservoir cover, diaphragm plate and diaphragm and slowly pump the brake lever a few times, until no air bubbles can be seen floating up..

Starting on the LEFT side calliper, pull the dust cap off the UPPER bleed valve. Attach one end of the clear plastic tube to the bleed valve and submerge the other end in the bottle. Carefully pump the brake lever three or four times and hold it while opening the calliper bleed valve. When the valve is opened, brake fluid will flow out of the calliper into the clear tube and the lever will move toward the handlebar. Retighten the bleed valve, then release the brake lever gradually. Repeat the process until no air bubbles are visible in the break fluid leaving the valve. Tighten the bleed valve with the specified torque and install the dust cap.

Ask a person to assist you by pumping the lever and the brake-pedal.

Repeat the procedure on the RIGHT side front calliper.Check the fluid-level and do not allow the fluid level to drop below the lower mark during the bleeding process. Then refit the reservoir cover with its diaphragm and diaphragm-plate

Rear Brake

Remove the seat cowling to gain access to the rear brake master cylinder fluid reservoir.

Unscrew the bolts (arrows) on each side, remove the grab-rail and release both pegs from the grommet (second arrow on the right) and carefully remove the cowling.

Start with the RIGHT side front caliper CENTRE bleed valve, remove the dust cap and attach the tube.Carefully pump the brake pedal a few times and hold it down while opening the centre bleed valve. When the valve is opened, brake fluid will flow out into the clear tube and the pedal will move fully downwards. Retighten the bleed valve, then release the brake pedal gradually. Repeat the process until no air bubbles are visible in the break fluid leaving the valve.

Repeat this process for the LEFT side front caliper.

Repeat the process for the rear caliper UPPER bleed valve. Check your fluid all times and be sure the fluid level never exceeds beneath the lower mark of your brake fluid cylinder.

Then move to the front LEFT calliper, push the secondary master cylinder (arrow «valve») and calliper upwards and bleed again the rear UPPER bleed valve. (so no break pedal, only pressure gaining by moving upwards the left calliper) Fill the rear fluid reservoir and tighten the cover with its diaphragm-plate

Mount the cowling

By pumping the pedal and lever beware of squirting brake fluid, so pump carefully.
