So you can safely start the new season, you should definitely check the condition of your brakes. In addition to checking the brake pads, changing the brake fluid is one of the most important "To Dos" before the first day on the track. With our instructions you can carry out your own brake fluid change yourself and you're on the safe side.

Some useful advice in advance

  1. The bleeding process shown can be applied to various hydraulic brake systems. Nevertheless, we recommend you to always keep your bike-specific features in mind. The manual will definitely help you.
  2. Be sure to keep everything clean during the bleeding process. Dirt in your hydraulic brake system is very difficult to remove and can damage your brake system.
  3. Always use the correct brake fluid (see manual). Using the wrong fluid can damage your brake system and affect the function of your brake.

You have read that? Then we can now start with the bleeding!

1. Preperation

Working steps:

  1. Open the master brake cylinder by removing the cap.
  2. Remove the cup seal and check its condition.
  3. Thoroughly clean all components with brake cleaner.
  4. Cover the master brake cylinder with a cleaning cloth so that no brake fluid runs out.
  5. Loosen the valve nut (slightly) on the brake caliper and remove the dust cap.

2. Changing the brake fluid

Working steps:

  1. Use the bleeding device to bleed the old brake fluid from the master brake cylinder.
  2. Put the hose on the bleed nipple and lock the vacuum lever.
  3. Open the valve nut completely. Now the old brake fluid will be sucked off downward.
    Attention! You have to constantly pour new brake fluid into the master brake cylinder during the bleeding so that no air will be sucked out.
  4. Close the valve nut.
  5. Insert the cup seal and close the master brake cylinder by hand tightening the screws.
  6. Clean your components with brake cleaner, so they won't be damaged by the aggressive brake fluid.

3. Function check / Brake test

Before hitting the track, you MUST test your brakes. You can do the first test immediately by controlling the pressure point. Then you should make a more extensive brake test on the track. Finished!
