This comprehensive guide delves into the intricacies of the parking brake, answering the fundamental question: is parking brake needed?
The Purpose of the Parking Brake
The primary function of the parking brake, also known as the emergency brake or handbrake, is to prevent the vehicle from rolling when parked. It achieves this by mechanically locking the rear wheels, ensuring the vehicle remains stationary even on an incline.
When to Use the Parking Brake
While the parking brake is primarily used when parking, it also serves other purposes:
- Emergency situations: In the event of a brake failure, the parking brake can be engaged to stop the vehicle.
- Hill starts: When starting on a steep incline, engaging the parking brake prevents the vehicle from rolling backward.
- Preventing theft: Engaging the parking brake makes it more difficult for unauthorized individuals to move the vehicle.
Types of Parking Brakes
There are two main types of parking brakes:
- Drum-style: Located within the rear brake drums, this type engages a lever to push the brake shoes against the drum.
- Disc-style: Found on vehicles with disc brakes, this type uses a caliper to squeeze the brake pads against the brake disc.
Using the Parking Brake Correctly
- Engage: Apply the parking brake by pulling or pushing the lever or pedal firmly.
- Disengage: Release the parking brake by pressing the release button or pedal and lowering the lever.
- Check: Always check if the parking brake is fully disengaged before driving.
Consequences of Not Using the Parking Brake
Failing to engage the parking brake can lead to severe consequences:
- Vehicle rolling: The vehicle may roll away, causing damage to other vehicles or property.
- Brake failure: Constant pressure on the brake pedal can lead to premature brake wear or failure.
- Safety hazard: An unsecured vehicle poses a safety risk to passengers, pedestrians, and other motorists.
Myths and Misconceptions
- Myth: The parking brake can damage the transmission.
- Fact: Engaging the parking brake while the vehicle is in gear does not harm the transmission.
- Myth: The parking brake is only needed on steep inclines.
- Fact: The parking brake should be used on any incline, regardless of the gradient.
- Myth: Using the parking brake frequently weakens it.
- Fact: Regular use of the parking brake helps maintain its functionality and prevents it from seizing up.
