Brake Fluid - Renew

Warning - General - Stabilise Motorcycle

warning
Make sure the motorcycle is stabilised and adequately supported.A correctly supported motorcycle will help prevent it from falling.An unstable motorcycle may fall, causing injury to the operator or damage to the motorcycle.
warning
Ensure absolute cleanliness when adding brake fluid to the brake fluid reservoir. Do not allow moisture or debris to enter the cylinder, as this will adversely affect the fluid properties. Always use fluid from a sealed container and do not use fluid from a container that has been opened for any period of time. Always check for fluid leakage around hydraulic fittings and for damage to hoses. A dangerous riding condition leading to loss of motorcycle control and an accident could result if this warning is ignored.
caution
Do not allow the fluid level to fall below the lower level mark in the reservoir. If the fluid level is allowed to fall below this mark, air may enter the system and the sequence of bleeding must be repeated.

Caution - Do not spill brake fluid

caution
To prevent paint damage, do not spill brake fluid onto any area of the bodywork. Spilled brake fluid will damage paintwork.

Front Brake Fluid

  • Note the original setting of the brake lever adjuster in order that it can be returned to the same position when the bleeding operation is complete. Set the brake lever adjuster to position No. 1.

    3. Screws

  3. Remove the screws from the brake reservoir cover.
  4. warning
    Ensure absolute cleanliness when adding brake fluid to the brake fluid reservoir. Do not allow moisture or debris to enter the cylinder as this will adversely affect the fluid properties. Always use fluid from a sealed container and do not use fluid from a container which has been opened for any period of time. Always check for fluid leakage around hydraulic fittings and for damage to hoses.A dangerous riding condition leading to an accident could result if this warning is ignored.
    caution
    To prevent body damage, do not spill brake fluid onto any area of the bodywork.
  5. Carefully remove the reservoir cover taking care not to spill any fluid.
  6. Check the condition of the sealing diaphragm for the reservoir. Replace if necessary.
  7. Remove the rubber cap from the bleed screw on the right hand caliper.
  8. Attach a transparent tube to the bleed screw.

    2. Bleed tube

    3. Container

  10. Place the other end of the tube in a suitable receptacle containing new brake fluid. Keep the tube end below the level of fluid.
  11. note
    The bleed screws should only be opened by a small angle, just enough to allow system pressure to drop. When pulling the brake lever or pushing the caliper pistons in, some resistance should be felt indicating that the screw is not opened too much.
  12. Partially open the bleed screw.
  13. note
    Pressure applied to the brake lever during the brake fluid renew process must be applied and removed smoothly and slowly. It must take a minimum of five seconds between lever positions (from fully released to stop).Failure to do this slowly can allow air to be drawn in to the system through the bleed screw threads.
  14. Get an assistant to slowly pull the brake lever to the handlebar and then slowly release the brake lever.
  15. Repeat step 9 until fresh brake fluid appears in the bleed tube.
  16. When fresh brake fluid is in the system, apply pressure to the brake lever, close the bleed screw and tighten it to 6 Nm.
  17. Remove the bleed tube and replace the bleed screw cap.
  18. Fill the reservoir to the upper level with new DOT 4 fluid.
  19. Repeat steps 5 to 13 for the other front brake caliper.
  20. When the brake fluid has been renewed, make sure the brake lever operation has a firm resistive feel to it, does not feel spongy and that the lever cannot be pulled directly back to the handlebar. Take remedial action as necessary.
  21. Refit the reservoir cap ensuring that the diaphragm seal is correctly positioned between the cap and the reservoir body. Tighten the fixings to 1.5 Nm.
  22. warning
    Always return the lever adjuster to the original setting as noted in paragraph 1. Operating the motorcycle with lever settings that are unfamiliar may lead to loss of control or an accident.
    warning
    It is dangerous to operate the motorcycle with defective brakes; you must have your authorised Triumph dealer take remedial action before you attempt to ride the motorcycle again. Failure to take remedial action may reduce braking efficiency leading to loss of motorcycle control and an accident.

Rear Brake Fluid

  1. Remove the cap from the rear bleed screw.
  2. Attach a transparent tube to the bleed screw.

  5. caution
    To prevent body damage, do not spill brake fluid onto any area of the bodywork.
  6. Unscrew and remove the rear brake reservoir cover taking care not to spill any fluid.

It must take a minimum of five seconds between lever positions (from fully released to stop).Failure to do this slowly can allow air to be drawn in to the system through the bleed screw threads.
  12. Get an assistant to slowly depress the brake pedal and then slowly release the brake lever.
  13. Repeat step 7 until fresh brake fluid appears in the bleed tube.
  14. When fresh brake fluid is in the system, apply pressure to the brake pedal, close the bleed screw and tighten it to 6 Nm.
  15. Remove the bleed tube and replace the bleed screw cap.
  16. Refit the reservoir cap ensuring that the diaphragm seal is correctly positioned between the cap and the reservoir body.
  17. Check the operation of the rear brake. Rectify as necessary.
  18. warning
