Land Rover Discovery: Pre -test and Functional Checks
NOTE:
For additional information on systems that must be checked, refer to the relevant Specification section in the Workshop Manual.
Pre-test and functional checks of systems which affect the safe and legal operations of the vehicle, such as brakes, lights and steering, must be carried out before the road test.
- Check operation of all lamps, horns and warning indicators.
- Check condition and operation of seats, seat belts and mirrors.
- Check condition and operation of windshield, wipers, blades and washer jets.
CAUTIONS:
- Brake fluid level should be between MIN and MAX based upon brake pad wear.
- Only top-up brake fluid level to MAX after new brake pads have been installed.
- If the brake fluid level is below MIN, visually check for any leaks.
Check brake fluid level.
- Check engine oil level.
- Check coolant level(s).
- Check tires, for correct pressure, compatible types and tread patterns, and wear within limits.
- Check there is sufficient fuel in the tank to complete the test.
- Check all around the engine, transmission and under the vehicle for oil, coolant, hydraulic and fuel leaks. Make a note of any apparent leaks and wipe off the surrounding areas to make it easier to identify the extent of the leak on completion of the test.
BRAKE TESTING
Avoid brake testing on busy roads where it can cause inconvenience or danger to other road users.
CAUTION:
Brake testing, which includes heavy brake applications, should not be carried out with new brake pads/discs until the components have bedded-in. New brake friction material will not reach full efficiency until the bedding-in process is complete.
Test the brakes at several speeds within the normal operating range using both light and heavy pedal pressure. Note any tendency to snatch, pull or drag, and any undue delay in application or release.
Allow the vehicle to coast and note any tendency to pull to one side, or evidence that the brakes are binding.
