| 1. Check uniformity of braking, – when pressing a brake pedal should not take away the car aside. By sharp pressing a pedal of a brake of a wheel should not be blocked prematurely. |
| 2. When braking vibrations of a wheel should not be felt. |
| 3. Check operation of the emergency brake. Wheels have to be blocked at rather small course of the lever. The emergency brake has to hold reliably the car on a slope. |
| 4. Check operation of the vacuum amplifier of brakes as follows. On the idle engine press a pedal of a brake of 4-5 times to let in air, then without removing a leg from a pedal, start the engine. |
| 5. After launch of the engine the pedal has to be displaced a little forward in response to increase of depression in the amplifier. In two minutes stop the engine. If now to press a brake pedal again, then from the amplifier hissing has to reach. After 4–5 pressing a brake pedal hissing has to stop, and the increased resistance has to be felt. |
