Required Brake Systems
Each commercial motor vehicle must have brakes adequate to stop and hold the vehicle. Each commercial motor vehicle must meet the applicable service, parking, and emergency brake system requirements provided in this section. Over the next few weeks, we will cover all of the required brake systems. Here’s the third one.
Each commercial motor vehicle must be equipped with a parking brake system that meets the applicable requirements of §393.41.
The parking brake must be able to be strong enough to hold the vehicle up to it’s GVWR (Gross Vehicle Weight Rating)
The professional driver can test this during the Pre-Trip Inspection by:
- Applying the parking brake
- Turning on the engine
- Placing their foot on the brake pedal
- Placing the vehicle in Drive
- Slowly releasing the brake pedal
If the vehicle doesn’t move, then the parking brake is working correctly.
If the vehicle moves, then the parking brake needs to be adjusted or replaced.
If the brake cannot be adjusted, then the vehicle should not be driven.
