The sight glass will darken when fluid is present.
If the sight glass remains clear, see a Harley Davidson dealer.
NOTE:
If the brake system is not leaking, there should never be a need to add fluid. If the fluid level
is low, the pads are probably worn and need to be replaced. By replacing the pads, the fluid
level will rise.
Use only DOT 4 BRAKE FLUID and replace the brake fluid every 2 years. See a Harley
Davidson dealer.
2. Verify that the front brake lever and rear brake pedal have a firm feel when applied. If brakes
are not firm, the brake system must be bled.

Brake Pads
Inspect brake pads for wear at service maintenance
intervals. If you ride under adverse conditions (steep hills,
heavy traffic, etc.), inspect more frequently. Excessively
worn brake pads can lead to brake failure, which could
result in death or serious injury. (00052a)
Always replace brake pads in complete sets for correct
and safe brake operation. Improper brake operation could
result in death or serious injury. (00111a)
Brakes are a critical safety component. Contact a Harley
Davidson dealer for brake repair or replacement.
