Hyundai Kona: Brake System / Brake Booster Repair procedures
| Brake Booster Operating Test |
| 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.
