| q | In petrol engines, the necessary vacuum is taken from the intake manifold |
| q | In diesel engines the vacuum is obtained by a fitted vacuum pump |
| q | Operating test: |
| – | With engine off, press the brake pedal hard several times (this reduces the existing vacuum in the servo brake). |
| – | Next, keep the brake pedal depressed halfway and start engine. If the servo brake is working correctly the brake pedal will give way notably (the servo brake effect is beginning) |
| q | If faulty, replace completely. |
| q | Non return valve (in the vacuum hose) |
