Brake Adjustment
Every moderate brake stop, the disc
brakes adjust for wear. If rarely
making moderate or heavier brake
stops, the brakes might not adjust
correctly. Very carefully making a
few moderate brake stops about
every 1 600 km (1,000 miles) will
adjust the brakes properly.
If the vehicle has rear drum brakes
and the brake pedal goes down
farther than normal, the rear drum
brakes might need adjustment.
Adjust them by backing up and
firmly applying the brakes a
few times.
Replacing Brake System Parts
The braking system on a vehicle is
complex. Its many parts have to be
of top quality and work well together
if the vehicle is to have really good
braking. The vehicle was designed
and tested with top-quality brake
parts. When parts of the braking
system are replaced, be sure to get
new, approved replacement parts.
If this is not done, the brakes might
not work properly. For example,
installing disc brake pads that are
wrong for the vehicle, can change
the balance between the front and
rear brakes—for the worse. The
braking performance expected can
change in many other ways if the
wrong replacement brake parts are
installed.
Brake Fluid
The brake/clutch master cylinder
reservoir is filled with DOT 3 brake
fluid as indicated on the reservoir
cap. See Engine Compartment
Overview on page 10‑6 for the
location of the reservoir.
There are only two reasons why the
fluid level in the reservoir might
go down:
.The fluid level goes down
because of normal brake lining
wear. When new linings are
installed, the fluid level goes
back up.
.A fluid leak in the brake/clutch
hydraulic system can also cause
a low fluid level. Have the brake/
clutch hydraulic system fixed,
