Leak Test

1. Install the vacuum gauge between the brake booster and check valve.

2. Start the engine, adjust the engine speed with the accelerator pedal so that the vacuum gauge readings show 40.0-66.7 kPa (300-500 mmHg, 11.8-19.7 in-Hg), then stop the engine.

3. Read the vacuum gauge.

If the vacuum reading decreases 2.7 kPa (20 mmHg, 0.8 in-Hg) or more after 30 seconds, check following parts for leaks.

CAUTION: Do not try to disassemble the brake booster. Replace the brake booster as an assembly with new one.
