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 defective.
2. With the engine stopped, step on the brake pedal several
times.
Then start the engine while the brake pedal is stepped
on.
If the pedal moves downward slightly, the booster is in
good condition. If there is no change, the booster is
defective.
