Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake pads for wear and
evenly tighten wheel nuts in the
proper sequence to torque
specifications. See
Brake pads should be replaced as
complete sets.
See your dealer if the brake pedal
does not return to normal height,
or if there is a rapid increase in
pedal travel. This could be a sign
that brake service might be
required.
Every time the brakes are applied,
with or without the vehicle moving,
the brakes adjust for wear.
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
braking performance expected can
change in many other ways if the
wrong replacement brake parts are
installed.
The brake/clutch master cylinder
reservoir is filled with DOT 3 brake
fluid as indicated on the reservoir
for the worse. The
cap. See
location of the reservoir.
There are only two reasons why the
brake fluid level in the reservoir
might go down:
The brake 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,
since a leak means that sooner
or later the brakes will not
work well.
Do not top off the brake/clutch fluid.
Adding fluid does not correct a leak.
If fluid is added when the linings are
worn, there will be too much fluid
when new brake linings are
installed. Add or remove fluid, as
necessary, only when work is done
on the brake/clutch hydraulic
system.
