Start and stop engine, after running for 1 to 2 minutes. b. Depress brake pedal several times with the same effort as used while normal braking operation and observe pedal travel. If pedal goes deep down for first time and its travel decreases for the following depression, then air tightness is observed. c. If pedal travel does not change then air tightness is not obtained. Inspect vacuum lines and sealing parts and replace defective parts. d. Repeat the entire test after replacing defective parts. 4. Check operation a. With engine stopped, depress pedal for several times with the same effort as used while normal braking operation and make sure that pedal travel doesn’t change. b. Start engine and depress brake pedal. A small increase in pedal travel indicated satisfactory functioning of booster. However, if there is no change in pedal travel, it indicates a malfunction. 5. Check air tightness under load a. Start engine. Depress brake pedal. Stop engine while holding the brake pedal in depressed condition. b. Hold the brake pedal in depressed condition for 30 seconds.
