CAR PULLS TO ONE SIDE
Be sure all other parts related to the front end are in
good working order before placing blame on the brakes.
Loose anchor pins or backing plates, improper lining,
wrong adjustment, broken return springs, drums out of
round, defective wheel cylinder, a binding disc caliper
piston, or a clogged or crimped hydraulic line can all
cause a vehicle to pull to one side during braking.
The most common cause for a soft or spongy brake
pedal will be air trapped in the hydraulic lines. This
problem may also be caused by a brake drum being cut
too thin when it is being resurfaced, and by weak or old
flexible brake lines.
BRAKES TOO HARD TO APPLY
his problem may be the result of grease or brake
fluid on the lining, pedal linkage binding, a faulty master
cylinder, or glazed brake linings.
BRAKES TOO SENSITIVE
Incorrect brake adjustment or brake lines or brake
lining fouled with grease or brake fluid maybe the cause
of sensitive brakes.
Before you determine a noise to be coming from the
brakes, eliminate all other possible sources, such as
body noise, loose front-end parts, loose lug nuts, and so
forth. Brake noise may be coming from shoes scraping
the backing plate, and also, loose brake lining (riveted),
loose anchor pins, loose or weak return springs, and
loose backing plates can all cause some sort of brake
BRAKE FLUID LOSS
Brake fluid loss is a serious problem caused by loose
fittings, leaking wheel cylinders, master cylinder, brake
lines, and hydraulic hoses.
BRAKES DO NOT SELF-ADJUST
The brake drum must be removed to check the
self-adjust mechanism. Worn or frozen star wheels,
broken or dislodged adjusting cable, or broken
hold-down clips will all cause the self-adjuster to
malfunction. See figure 6-6 for an illustration of an
automatic adjuster components list.
BRAKE WARNING LAMP WILL NOT GO
If the brake failure warning lamp comes on, it is a
signal that one of the two hydraulic circuits has
malfunctioned. Check the entire system and after you
