Initial Test Drive

IMPORTANT POINTS TO REMEMBER
To determine if the problem is in the front or rear braking system, first apply the service brake pedal, then apply only the parking brake.
- If the condition (i.e. pull, vibration, pulsation) occurs only with the service brake, the problem is in the front system.
- If the condition occurs when the parking brake is applied (and does not occur with the service brake applied), the problem is in the rear system.

WARNING: Be careful not to inadvertently lock up the wheels when braking with the parking brake, you may not be able to quickly release it.

The brake system should be tested at different vehicle speeds using both light and heavy brake pedal pressure.
Avoid locking the brakes and sliding the tires. Locked brakes and sliding tires do not indicate brake efficiency.

Proper rear brake adjustment is crucial in diagnosing brake problems. Rear drum brakes which are out of adjustment will result in a low pedal and a loose emergency brake.

If there is a problem with the "feel" or travel of the brake pedal or parking brake always adjust the shoes/linings first.

WARNING: Before test driving any vehicle, perform the following checks:






1. Depress the brake pedal to check for adequate pedal reserve (minimum of 25%). If the pedal sinks to the floor, do not test drive the vehicle.
2. Check the fluid level in the master-cylinder and refill as necessary.
3. Test the emergency brake. Adjust or repair as necessary prior to test driving the vehicle.
4. Obey all traffic and safety regulations.
5. Perform a series of low speed stops and verify the brakes have sufficient stopping power for a safe test drive.

WHERE TO TEST DRIVE
The test drive location should be:
- Free of all other traffic.
- Relatively smooth, level, and uncrowned.
- Free of gravel or bumps.
