Check the brake fluid after the first 1000 km (621 mi) and then every 4000 km (2485 mi) or 12 months, change it every year.
Warning!
- In case of excessive stroke of the brake lever, excessive elasticity, or air bubbles, bleed the air out of the circuit, see 2.12.5.
- When using the brake fluid, take care not to spill it on the plastic or painted parts, since it can damage them.
- Before starting, check that the brake lines are neither twisted nor worn out and that the connectors are not leaking.
- Do not use or mix different types of silicone or oil fluids.
- Do not use neither old brake fluid nor fluid taken from containers opened for a long time. Prevent water or dust from accidentally getting into the circuit.
Check
Note. Place the vehicle on a firm and flat surface.
Position the vehicle on the stand and steer the handlebar completely rightwards.
Make sure that the fluid level exceeds the "MIN" mark.
If the fluid does not reach at least the "MIN" mark, proceed as follows:
Warning! When the disc pads wear out, the level of the fluid decreases progressively to compensate for their wear.
Check the brake pad wear, see 2.12.3.
If the pads and/or the disc do not need replacing, provide for topping up.
Topping up
Warning! The brake fluid may flow out of the tank. Do not operate the front brake lever if the brake fluid tank plug is loose or has been removed. Use a cloth under the brake fluid tank.
Unscrew and remove the cover (1).
Warning!
- Avoid any prolonged exposure of the brake fluid to the air.
- The brake fluid is hygroscopic and when in contact with the air it absorbs its humidity. Leave the brake fluid tank open ONLY for the time necessary for topping up.
Remove the gasket (2).
Note. In order not to spill the brake fluid while topping up, do not shake the vehicle.
Top up tank (3) with brake fluid, see 1.8.1 until reaching the correct level between the "MIN" and "MAX" marks.
Warning!
- Do not exceed the "MAX" level while topping up.
- It is advisable to top up until reaching the "MAX" level only with new pads.
- When the disc pads wear out, the level of the fluid decreases progressively to compensate for their wear.
- Do not reach the "MAX" level with worn out pads, since this will cause a fluid outflow when the pads are changed.
To refit components, follow the disassembly procedure in reverse order.
