Once a brake system is set to
specifications, changing any one of its
components or any combination of
components may degrade the system. All
parts have to work together to perform as
they should.
Your brake system is hydraulically
operated. Refer to Service Brake
Component Inspection on page 216 for
more information on inspecting the brakes.
Any replacement components in the brake
system must meet the specifications of the
original components. Any changes from
the original specifications can affect the
performance of the entire system.
WARNING
Do not use any replacement part in the
brake system unless it conforms ex-
actly to original specifications. A non-
conforming part in your vehicle's brake
system could cause a malfunction re-
sulting in an injury accident. Consult
you local dealer for suitable replace-
ment parts.
WARNING
Do not work on the brake system with-
out
the parking brake set, the keys re-
moved from the vehicle, and wheels
chocked securely. If the vehicle is not
properly secured to prevent inadver-
tent vehicle movement, it could roll
and cause serious personal injury or
damage to the vehicle.
• Use wood blocks (4 in. X 4 in. X
6 in. or larger) against the front
and rear surfaces of the tires. Be
sure the vehicle cannot move.
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 hy-
draulic 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 system. Brake fluid is
used in the master cylinder and brake
pipes. Do not mix these fluids when re-
plenishing the system or seal damage
can result.
CAUTION
Hydraulic brake fluid may damage
painted surfaces of the vehicle.
