The parking brake, also known as the handbrake or emergency brake, is a crucial safety feature in vehicles that helps prevent the vehicle from rolling or moving when parked on an incline. However, have you ever wondered which wheels the parking brake controls? This seemingly simple question has sparked debate among car enthusiasts and mechanics, with some claiming it’s the rear wheels, while others argue it’s the front wheels. In this comprehensive blog post, we’ll delve into the world of parking brakes and explore the intricacies of how they work, the types of parking brakes, and which wheels they control.

The Importance of Parking Brakes
Parking brakes are an essential safety feature in vehicles, and their proper functioning can mean the difference between life and death. When a vehicle is parked on an incline, the parking brake helps to prevent it from rolling or moving, which can lead to accidents, injuries, or even fatalities. In addition to safety, parking brakes also play a crucial role in preventing damage to the vehicle and its surroundings. A malfunctioning parking brake can cause the vehicle to roll or move, leading to costly repairs and potential damage to property.
Moreover, parking brakes are an important aspect of vehicle maintenance. Regular checks and maintenance of the parking brake can help ensure its proper functioning, which is essential for safe driving. In this blog post, we’ll explore the world of parking brakes, including the types of parking brakes, how they work, and which wheels they control.
Types of Parking Brakes
There are two main types of parking brakes: mechanical and electronic. Mechanical parking brakes use a cable or rod to connect the brake pedal to the rear wheels, while electronic parking brakes use an electric motor to engage the rear wheels. In this section, we’ll explore the differences between these two types of parking brakes.
Mechanical Parking Brakes
Mechanical parking brakes are the most common type of parking brake. They use a cable or rod to connect the brake pedal to the rear wheels, which are typically equipped with a parking brake lever or pedal. When the parking brake is engaged, the cable or rod pulls the rear wheels towards the vehicle, applying pressure to the brake pads and preventing the vehicle from rolling or moving.
The mechanical parking brake system consists of the following components:
- Cable or rod: connects the brake pedal to the rear wheels
- Parking brake lever or pedal: engages and disengages the parking brake
- Brake pads: apply pressure to the rear wheels when the parking brake is engaged
- Rear wheel bearings: support the rear wheels and allow them to rotate
Electronic Parking Brakes
Electronic parking brakes, on the other hand, use an electric motor to engage the rear wheels. They are typically found in modern vehicles with advanced safety features. Electronic parking brakes use a sensor to detect when the vehicle is parked on an incline and automatically engage the rear wheels to prevent the vehicle from rolling or moving.

The electronic parking brake system consists of the following components:
- Electric motor: engages and disengages the rear wheels
- Sensor: detects when the vehicle is parked on an incline
- Control unit: controls the electric motor and sensor
- Rear wheel bearings: support the rear wheels and allow them to rotate
Which Wheels Does the Parking Brake Control?
The age-old question: which wheels does the parking brake control? The answer is not as simple as it seems. In most vehicles, the parking brake controls the rear wheels, but there are some exceptions. In this section, we’ll explore the different types of parking brake systems and which wheels they control.
Rear-Wheel Parking Brakes
In most vehicles, the parking brake controls the rear wheels. This is because the rear wheels are typically the ones that are most prone to rolling or moving when parked on an incline. The parking brake system uses a cable or rod to connect the brake pedal to the rear wheels, which are equipped with a parking brake lever or pedal.
The rear-wheel parking brake system consists of the following components:
- Cable or rod: connects the brake pedal to the rear wheels
- Parking brake lever or pedal: engages and disengages the parking brake
- Brake pads: apply pressure to the rear wheels when the parking brake is engaged
- Rear wheel bearings: support the rear wheels and allow them to rotate
Front-Wheel Parking Brakes
Some vehicles, particularly those with all-wheel drive or four-wheel drive systems, use a front-wheel parking brake. In these vehicles, the parking brake controls the front wheels, which are typically equipped with a parking brake lever or pedal.
The front-wheel parking brake system consists of the following components: (See Also: How to Release Electronic Parking Brake Manually? Easy Steps Ahead)
- Cable or rod: connects the brake pedal to the front wheels
- Parking brake lever or pedal: engages and disengages the parking brake
- Brake pads: apply pressure to the front wheels when the parking brake is engaged
- Front wheel bearings: support the front wheels and allow them to rotate
All-Wheel Parking Brakes
Some high-performance vehicles, particularly those with all-wheel drive or four-wheel drive systems, use an all-wheel parking brake. In these vehicles, the parking brake controls all four wheels, which are typically equipped with a parking brake lever or pedal.
The all-wheel parking brake system consists of the following components:
- Cable or rod: connects the brake pedal to all four wheels
- Parking brake lever or pedal: engages and disengages the parking brake
- Brake pads: apply pressure to all four wheels when the parking brake is engaged
- Front and rear wheel bearings: support the front and rear wheels and allow them to rotate
