Bleeding the Front Brakes
Brake Fluid Replacement - Routine Maintenance
Braking performance reduces as brake fluid ages, Repeated stops cause brake fluid to
heat and cool rapidly reducing braking performance. Brake fluid absorbs moisture over a
period of time and becomes contaminated as it ages.
Therefore brake fluid should be replaced at specified intervals as instructed in the
routine maintenance schedule, see Brake Fluid - Renew.
Brake Bleeding
When removing or replacing brake components and the brake line is opened air will
enter as fluid escapes.
If the brake bleed procedure is not carried out air can become trapped in the brake fluid.
A consequence of air being trapped in the brake system is that the brake can feel
soft/spongy and the performance of the brakes will be reduced.
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.
Brake fluid is hygroscopic which means it will absorb moisture from the air.
Only use new DOT 4 brake fluid from a sealed container, do not mix different brands
of brake fluid and never use brake fluid from an unsealed container or from one that
has been previously opened.
Any absorbed moisture will greatly reduce the boiling point of the brake fluid.
Moisture in the braking system may a cause a reduction in braking efficiency leading
to loss of motorcycle control and an accident.
