booster by pumping the brake pedal several

2. Push the pedal down and hold in this position.

3. Start the engine.

4. The booster is OK if the pedal drops further

because of extra force produced.

is probably defective and should be checked. If no

defect is revealed by checking the vacuum system,

the defect is in the booster itself.
