Brake Chatter Brake chatter is usually caused by loose or worn components, or
glazed or burnt linings. Rotors with hard spots can also contribute to
brake chatter. Additional causes of chatter are out - of- tolerance rotors,
brake lining not securely attached to the shoes, loose wheel bearings
and contaminated brake lining.

Operation and Leakage Check
Check all of the following items:
Component Procedure
Brake Booster (A) Check brake operation by applying the brakes during a test drive. If the brakes do not
work properly, check the brake booster. Replace the brake booster as an assembly if it
does not work properly or if there are signs of leakage.
Piston cup and pressure cup
inspection (B) a.
Check brake operation by applying the brakes. Look for damage or signs of fluid
leakage. Replace the master cylinder as an assembly if the pedal does not work
properly or if there is damage or signs of fluid leakage.
b. Check for a difference in brake pedal stroke between quick and slow brake
applications. Replace the master cylinder if there is a difference in pedal stroke.
Brake hoses (C) Look for damage or signs of fluid leakage. Replace the brake hose with a new one if it
is damaged or leaking.
Caliper piston seal and
piston boots (D) Check brake operation by applying the brakes.
Look for damage or signs of fluid leakage. If the pedal does not work properly, the
brakes drag, or there is damage or signs of fluid leakage, disassemble and inspect the
brake caliper. Replace the boots and seals with new ones whenever the brake caliper
is disassembled.
BRAKE BOOSTER OPERATING TEST
For simple checking of the brake booster operation, carry out the following tests
1. Run the engine for one or two minutes, and then stop it. If the pedal depresses fully the first time but gradually
becomes higher when depressed succeeding times, the booster is operating properly, if the pedal height remains
unchanged, thebooster is inoperative.

2.With the engine stopped, step on the brake pedal several times.
Then step on the brake pedal and start the engine. If the pedal moves downward slightly, the booster is in good
condition. If there is no change, the booster is inoperative.
3.With the engine running, step on the brake pedal and then stop the engine.
Hold the pedal depressed for 30 seconds. If the pedal height does not change, the booster is in good condition, if
the pedal rises, the booster is inoperative.
If the above three tests are okay, the booster performance can be determined as good.
Even if one of the above three tests is not okay, check the check valve, vacuum hose and booster for malfunction.
VACUUM HOSE (CHECK VALVE)
INSPECTION
1. Disconnect the brake booster vacuum hose (check valve built in) (A) at the booster (B).
2. Start the engine and let it idle. There should be vacuum available. If no vacuum is available, the check valve is not
working properly. Replace the back booster vacuum hose and check valve and retest.
