The service brakes fail in a vehicle with a conventional parking-brake lever. What should the driver avoid?
Correct answer: Suddenly pulling the parking brake hard while traveling at speed.
Why
Keep control, release the accelerator and work toward a safe stopping place. The guide advises a lower gear to help slow and gradual use of the parking brake rather than a sudden application. Follow the vehicle manufacturer’s emergency instructions, especially for different parking-brake systems. Do not continue driving after stopping without working brakes; obtain help.
