Road test (Every 12 000 miles (20 000 km) or 12 months)
Instruments and electrical
equipment
1 Check the operation of all instruments and
electrical equipment.
2 Make sure that all instruments read correctly, and switch on all electrical equipment in turn to check that it functions properly.
Steering and suspension
3 Check for any abnormalities in the steering,
suspension, handling or road “feel”.
4 Drive the vehicle, and check that there are no unusual vibrations or noises.
5 Check that the steering feels positive, with no excessive “sloppiness”, or roughness, and check for any suspension noises when cornering, or when driving over bumps.
Drivetrain
6 Check the performance of the engine,
clutch, transmission and driveshafts.
7 Listen for any unusual noises from the engine, clutch and transmission.
8 Make sure that the engine runs smoothly when idling, and that there is no hesitation when accelerating.
9 Where applicable, check that the clutch action is smooth and progressive, that the drive is taken up smoothly, and that the pedal travel is not excessive. Also listen for any noises when the clutch pedal is depressed.
10 Check that all gears can be engaged smoothly, without noise, and that the gear lever action is not abnormally vague or “notchy”.
Check the operation and
performance of the braking
system
11 Make sure that the vehicle does not pull to
one side when braking, and that the wheels
do not lock prematurely when braking hard.
12 Check that there is no vibration through the steering when braking.
13 Check that the handbrake operates correctly, without excessive movement of the lever, and that it holds the vehicle stationary on a slope.
14 Test the operation of the brake servo unit as follows. With the engine off, depress the footbrake four or five times to exhaust the vacuum. Start the engine, holding the brake pedal depressed. As the engine starts, there should be a noticeable “give” in the brake pedal as vacuum builds up. Allow the engine to run for at least two minutes, and then switch it off. If the brake pedal is depressed now, it should be possible to detect a hiss from the servo as the pedal is depressed.
After about four or five applications, no further hissing should be heard, and the pedal should feel considerably firmer.
