KTM 390 Adventure - Owner's Manual > Adding rear brake fluid

Warning: Danger of accidents

An insufficient brake fluid level will cause the brake system to fail.

If the brake fluid level drops below the MIN marking, the brake system is leaking or the brake linings are worn down.

• Check the brake system and do not continue riding until the problem is eliminated. (Your authorized KTM workshop will be glad to help.)

Warning: Skin irritation

Brake fluid causes skin irritation.

• Keep brake fluid out of the reach of children.
• Wear suitable protective clothing and safety glasses.
• Do not allow brake fluid to come into contact with the skin, the eyes or clothing.
• Consult a doctor immediately if brake fluid has been swallowed.
• Rinse the affected area with plenty of water in the event of contact with the skin.
• Rinse eyes thoroughly with water immediately and consult a doctor if brake fluid comes into contact with the eyes.
• If brake fluid spills on to your clothing, change the clothing.

Warning: Danger of accidents

Old brake fluid reduces the braking effect.

• Make sure that brake fluid for the front and rear brake is changed in accordance with the service schedule. (Your authorized KTM workshop will be glad to help.)

Note

Environmental hazard

Hazardous substances cause environmental damage.

• Dispose of oils, grease, filters, fuel, cleaning agents, brake fluid, etc., correctly and in compliance with the applicable regulations.

Info Never use DOT 5 brake fluid. It is silicone-based and purple in color. Oil seals and brake lines are not designed for DOT 5 brake fluid.

Avoid contact between brake fluid and painted parts. Brake fluid attacks paint.

Only use clean brake fluid from a sealed container.

Guideline

Checking the rear brake linings

Warning: Danger of accidents

Worn-out brake linings reduce the braking effect.

• Ensure that worn-out brake linings are replaced immediately. (Your authorized KTM workshop will be glad to help.)

Warning: Danger of accidents

Damaged brake discs reduce the braking effect.

If the brake linings are not changed in time, the brake lining carriers grind against the brake disc. As a consequence, the braking effect is greatly reduced and the brake discs are destroyed.

• Check the brake linings regularly.

• Check the brake linings for minimum thickness A.

• If the minimum thickness is less than specified:
  • Change the rear brake linings.

• Check the brake linings for damage and cracking.
  • If there is wear or tearing:
    • Change the rear brake linings.
