What should be done after reapplying the parking brake during a final brake test?

After reapplying the parking brake during a final brake test, the appropriate action is to remove all wheel blocks. This step is crucial because removing the wheel blocks ensures that the vehicle is free to move safely and correctly when it is put into operation after the brake test. The presence of wheel blocks is a precaution to prevent movement when the vehicle is not intended to be driven; however, once the parking brake has been confirmed as functional through the brake test, it is safe to proceed by removing them.

The other options, while important in different contexts, are not necessary immediately after reapplying the parking brake during the final brake test. For instance, turning off the engine or disconnecting the battery might be considered during other maintenance or safety procedures but are not directly related to the immediate follow-up actions of ensuring the brakes are ready for safe operation. Testing tire pressure, although important for overall vehicle safety, does not pertain specifically to the parking brake function or the final brake test process.
