To check the fluid level, simply look at the
see–through reservoir. The level should be between
the "MAX" and "MIN" lines on the tank.
It is normal for the brake fluid level to go down slightly as
the brake pads wear. So be sure to keep the reservoir
filled.
If the reservoir needs frequent refilling, it may indicate a
serious mechanical problem.
If the level is low, add FMVSS No.116 DOT 3 or SAE
J1703 brake fluid to the brake reservoir.
Remove and replace the reservoir cap by hand. Add
brake fluid up to the "MAX" line.
Use only newly opened brake fluid. Once opened, brake
fluid absorbs moisture from the air, and excess moisture
can cause a dangerous loss of braking efficiency.
CAUTION
Take care when filling the reservoir because brake fluid
can harm your hands or eyes and damage painted
surfaces. If fluid gets in your hands or eyes, flush them
with clean water immediately. If you still feel
uncomfortable with your hands or eyes, go to the
doctor.
