Grand Vitara 2WD V6-27L (2006) Brake Booster Component Locations
Vacuum Brake Booster: Testing and Inspection
Booster Operation Check
There are two ways to perform this inspection, with and without a tester. Ordinarily, it is possible to roughly determine its condition without using a
tester.
NOTE:
For this check, make sure that no air is in hydraulic line.
Inspection without Tester
Check air tightness
1. Start engine.
2. Stop engine after running for 1 to 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 and more times, air tightness is obtained.
4. If pedal travel doesn't change, air tightness isn't obtained.
NOTE:
If defective, inspect vacuum lines and sealing parts, and replace any faulty part. When this has been done, repeat the entire test.
