Step 1: Make sure you have the tools to bleed your brake fluid. The tools you require will vary, but generally this is what you will need:
A. Wrench/Spanner (average 10mm) B. Brake bleeding kit (rubber fitting, clear hose, small container) C. Brake fluid overflow container (to put the brake bleeding kit small container in) D. Rags E. Brake Fluid (check what type of brake fluid you need for your bike. e.g. DOT 3). Make sure to buy enough brake fluid in the DOT type you require. (500ml should be more than enough).
Step 2: Attach the brake bleeding kit to the brake fluid nipple located on the brake caliper.
Step 3: Loosen the nipple so the fluid is free to flow down the brake bleeding kit tube and into the small container
Step 4: Remove the master cylinder cap (top) so you can monitor and refill more brake fluid into the master cylinder as you bleed the brakes.
Step 5. Pump the brake lever so the old/new brake fluid is forced through the tube into the brake bleeding kit fluid container
Step 6: Keep the volume of the master cylinder constant (near full) as to not have it empty. Keep pumping on the brake lever until the fluid coming out is clear (rather than the old brown/black colour).
Step 7: Once all the tiny air bubbles are gone hold pressure on the brake level and re-tighten the brake fluid nipple to close it off.
Step 8: Replace the master cylinder top cover.
Step 9: Remove the brake bleeding kit from the cliper and use the rag with water to clean up any spillage.
