Kia Optima: 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, the booster 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.
