Brake Fluid Check and Refill
WARNING! Wear protective clothing when han-
dling hydraulic fluid. It is mildly toxic and can
cause skin and eye irritation.
WARNING! Use only the type of hydraulic fluid
specified. Do not use or mix different types of
hydraulic fluid. The wrong hydraulic fluid will
damage the rubber parts of the brake system
which may lead to loss of braking and possibly
cause serious personal injury.
CAUTION: Hydraulic brake systems use two dis-
tinct and incompatible fluids. Power steering
fluid is used in the hydraulic brake booster sys-
tem. Brake fluid is used in the master cylinder
and brake pipes. Do not mix these fluids when
replenishing the system or seal damage can
result.
CAUTION: Hydraulic brake fluid may damage
painted surfaces of the vehicle.
Make sure that the fluid level registers on or above the fluid
level mark molded on the reservoir - add more if necessary,
as follows:
1. Remove each reservoir cap and extract the rubber dia-
phragm from each reservoir.
2. Fill each reservoir with clean hydraulic fluid of the
approved specification (DOT 3 brake fluid).
3. Insert the rubber diaphragms into the reservoirs.
4. To prevent leakage from the reservoirs, ensure that the
seal in each reservoir cap is in good condition before
refitting the cap.
