Maintenance
Caution
1. Top-ups should only be carried out with DOT 4 classified
brake fluid.
2. The braking circuit fluid is highly corrosive. Therefore,
when topping it up, avoid letting it come into contact with
the painted parts of the vehicle. The braking circuit fluid
is hygroscopic, that is, it absorbs humidity from the
surrounding air. If moisture contained in the brake fluid
exceeds a certain value, this will result in inefficient
braking.
3. Proper Brake fluid bleeding and no leakage at all joints
need to be ensured during each re-assembly of the front
suspension/steering column system.
Warning
In normal climatic conditions it is advisable to replace the
above-mentioned fluid every 2 year. Never use brake
fluid contained in containers which are already open or
partially used.
