Mastering the Electric Handbrake: How to Drive a Car with an Electric Park Brake

Whether you're driving a traditional gasoline car or an electric or hybrid vehicle, the concept of a park brake has remained largely similar. However, electric handbrakes have been increasingly popular, particularly in modern vehicles. Here's a comprehensive guide to understanding and using these advanced park brake systems, with insights from various vehicle models.

Understanding Electric Handbrakes

Electric handbrakes, also known as electric or electronic park brakes, have evolved significantly over the years. They generally work by using electric motors integrated into the rear brake calipers. Unlike traditional mechanical handbrakes that rely on a mechanical linkage and cables, electric handbrakes use a control unit that communicates with the vehicle's computer to deploy and release the brake.

Types of Electric Handbrakes

There are several types of electric handbrakes, each with its own unique features and benefits. The most common type utilizes hybrid hydraulic service brakes, where the rear brake calipers serve as both hydraulic and electric components. This means they can provide both normal braking and park brake functionality.

Other systems use a control unit that communicates with other vehicle systems, such as the CANbus network, to deploy and release the park brake. Some advanced vehicles also offer additional features like auto release and emergency deployment systems. The on/off switch, which is often located in the cabin, can sometimes have alternative functions like 'auto,' which can be used to turn off the auto release function.

Vehicle-Specific Examples

To illustrate the functionality and usage of an electric handbrake, let's take a look at a few specific vehicle examples. Consider a 2011 Nissan: when you select forward or reverse, the car comes out of park, and when you shut it off, it automatically parks itself. This type of system is often seen in older vehicles as well.

For instance, in a 2015 VW Golf Mk7, the electric handbrake is a small button located on the central console below the gear shift. To use it, simply lift it slightly when the car is stationary, and the rear wheels will be braked by electric actuators. You can drive off without releasing anything, as is the case with many modern cars. While many drivers prefer this method, some may find that other features like 'autohold' can be bothersome as they may dazzle drivers behind. Autohold applies all the vehicle's brakes and turns on the brake lights, which may not be ideal in certain driving situations.

Another example is the Land Rover AWD vehicle, which uses a transmission brake that typically locks the propeller shaft to prevent the vehicle from rolling. This type of brake is more complex and provides a different level of functionality compared to traditional electric handbrakes.

Using an Electric Handbrake

Using an electric handbrake is straightforward, but it's important to understand how it works in your particular vehicle. Most electric handbrakes are engaged by lifting a button or lever, which activates an electric motor to hold the car in place. To release the brake, simply press the lever with your foot and travel can be initiated.

For example, in the VW Golf Mk7, the electric handbrake can be left engaged while the car is stationary, allowing you to set it in gear without worrying about the car rolling. This is particularly useful in stop-and-go traffic or while waiting at a red light. Many drivers prefer this method because it is less noticeable than the 'autohold' feature, which can confuse other drivers by flashing the brake lights unnecessarily.

Conclusion

Understanding and mastering the electric handbrake can significantly enhance your driving experience. Whether you're driving a traditional gasoline car or a more modern electric or hybrid vehicle, these advanced park brake systems can provide convenience and added safety. By familiarizing yourself with the mechanics and features of your vehicle's electric handbrake, you can drive more efficiently and with greater peace of mind.
