Power Brake Assist: Testing and Inspection
Brake Booster Function Inspection
NOTE:
Make sure that air is not contained in hydraulic line before doing this check.
Air Tightness Inspection
1) Start engine.
2) Stop engine after running it for 2 minutes.
3) Depress brake pedal several times with the same load as in ordinary braking and observe pedal travel. If pedal goes down deep the first time but its
travel decreases as it is depressed the second time and after, air tightness is obtained.
4) If pedal travel does not change, air tightness is not obtained.
5) If defective, inspect vacuum lines and sealing parts, and replace the faulty part. After this, repeat the entire test.
