CHECKING BRAKE FLUID

63R001b
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 cover 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.
NOTICE
If you spill some of the fluid, be sure to wipe it off to prevent it
from damaging the parts or paintwork.
