How the Parking Brake Works
The parking brake, also known as the handbrake or emergency brake, serves as a crucial safety feature in a vehicle. It operates on the principle of friction to prevent the car from moving when parked on an incline or decline.
Engaging the parking brake involves pulling up a lever or pressing a button to activate the mechanism, ensuring that the wheels are securely locked in place.
Parking Brake Mechanics
When the driver activates the parking brake, it engages a separate braking system from the main brakes, providing an additional level of security for the parked vehicle.
The parking brake mechanics work as follows:
- The driver pulls the parking brake lever, which is connected to cables or electronic actuators.
- The cables or electronic actuators transmit the force to the rear brakes, engaging them to hold the vehicle in place.
- In some vehicles, the parking brake is integrated into the rear brake calipers, while in others, it operates on separate rear brake shoes.
- Releasing the parking brake lever or button relaxes the tension on the cables or deactivates the electronic actuators, allowing the rear brakes to disengage.
Understanding these parking brake mechanics is essential for drivers to use this feature effectively and ensure the safety of their parked vehicle.
Engaging the Brake
Upon activation, the driver’s control of the parking brake initiates a specific set of mechanisms that securely hold the vehicle in place. Engaging the parking brake involves pulling up on a lever or pressing a button, depending on the vehicle’s make and model.
This action triggers a cable connected to the rear brakes, causing the brake pads to clamp down on the brake rotor or drum.
The parking brake works independently of the hydraulic brake system, providing an additional layer of security.
Below is a table outlining the basic steps involved in engaging the parking brake.
- Stop the vehicle
- Put the transmission in ‘Park’ (for automatic) or in gear (for manual)
- Engage the parking brake by pulling the lever or pressing the button
When to Use the Parking Brake
A parking brake should be used whenever a vehicle is parked on an incline, regardless of the steepness. This is essential for ensuring the vehicle remains stationary and does not roll downhill.
