BASIC OPERATION
BRAKES
After driving in rain for some time without applying the brakes, or any time brake components
such as the brake rotors and pads are wet or cold, the first braking action can be less effective.
Increasing pressure at the brake levers may be necessary to obtain desired results. Briefly
applying light pressure to the brakes will help to dry the brakes when wet. Reduce speed in wet
conditions to give yourself more time for stopping.
Applying light pressure to the brakes for an extended period, such as on long downhill grades,
will cause excessive and premature wear of the brakes. It can also result in the brakes
overheating, causing significant reduction in their effectiveness.
