Land Rover Discovery: 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 components will not reach full efficiency until the bedding-in process is complete. Note that when new parking brake shoes or rear brake discs have been installed, it is essential that the 'bedding-in' procedure is carried out.
For additional information, refer to: Electronic Parking Brake Service Mode Activation and Deactivation (206-05 Parking Brake and Actuation, General Procedures).
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.
After stopping the vehicle (not immediately after a period of heavy braking), carefully check the brake temperature. A disc which feels appreciably hotter than the others, could indicate that the pads on that disc are binding.
After completion of the test, check for:
- Oil, coolant, hydraulic, air and fuel leaks.
- Abnormal temperature of any moving components or assemblies, e.g. wheel hubs, transmission etc., which might indicate over tightness or lack of lubrication.
ROLLING ROAD TESTING
FOUR-WHEEL ROLLING ROAD
CAUTION:
When utilising a four-wheel rolling road for testing, ensure all relevant health and safety requirements are adhered to.
Provided that front and rear rollers are rotating at identical speeds and that normal workshop safety standards are applied, there is no speed restriction during testing except any that may apply to the tires.
Ensure that the parking brake is released prior to engaging roller driving mechanism.
TWO-WHEEL ROLLING ROAD
CAUTION:
On no account should an attempt be made to carry out any form of testing on a two-wheel rolling road.
