Hand Brake System in Car
Introduction
The hand brake, also known as the parking brake or emergency brake, is a mechanical device that is used to keep a vehicle stationary when it is not in motion. It is typically operated by a lever or pedal that is located in the center console or near the driver’s seat. When the hand brake is engaged, it locks the rear wheels of the vehicle, preventing it from rolling.
Types of Hand Brakes
There are two main types of hand brakes:
* Mechanical hand brakes are the most common type. They use a cable or rod to connect the hand brake lever or pedal to the brake calipers on the rear wheels. When the hand brake is engaged, the cable or rod pulls on the brake calipers, which in turn applies pressure to the brake pads and rotors, locking the wheels.
* Hydraulic hand brakes use a hydraulic system to engage the rear brakes. When the hand brake is engaged, a master cylinder sends brake fluid to the brake calipers on the rear wheels. The brake fluid then applies pressure to the brake pads and rotors, locking the wheels.
Advantages and Disadvantages of Hand Brakes
**Advantages:**
* Hand brakes are simple to operate and can be used in any type of vehicle.
* Hand brakes are relatively inexpensive to maintain.
* Hand brakes can be used to control the vehicle’s speed on steep hills.
* Hand brakes can be used to prevent the vehicle from rolling away when it is parked.
**Disadvantages:**
* Hand brakes can be difficult to engage and disengage, especially in cold weather.
* Hand brakes can cause the rear wheels to lock up, which can lead to loss of control of the vehicle.
* Hand brakes can wear out over time, which can reduce their effectiveness.
How to Use a Hand Brake
To engage the hand brake, simply pull up on the lever or push down on the pedal. To disengage the hand brake, push down on the release button located on the lever or pedal.
When to Use a Hand Brake
The hand brake should be used whenever the vehicle is not in motion and is parked on a slope. The hand brake can also be used to control the vehicle’s speed on steep hills.
Maintenance of Hand Brakes
Hand brakes require very little maintenance. However, it is important to have the hand brake inspected regularly to ensure that it is functioning properly. The hand brake cable or rod should be lubricated every year to prevent it from freezing up. The brake pads and rotors should also be inspected regularly for wear and tear.
Conclusion
The hand brake is an important safety feature that should be used whenever the vehicle is not in motion and is parked on a slope. Hand brakes are relatively inexpensive to maintain and can help to prevent the vehicle from rolling away.
