Does Driving with the Parking Brake On Damage the Car?

Driving with the parking brake on might seem like an easy solution when you're in a hurry or in a tight spot, but it can indeed cause serious damage to your vehicle. Brake pads, drums, rotors, and cables are all at risk when under constant tension, and the potential consequences can range from minor wear and tear to complete brake failure. In this article, we'll explore the risks and provide recommendations to ensure your car stays in top shape.

Understanding the Potential Damage

When the parking brake is engaged during driving, it can lead to several types of damage, depending on the duration and intensity of use.

Brake Pads and Shoes

Continuous heat generated by the brakes can cause brake pads and shoes to overheat and wear out prematurely. This can lead to a decrease in braking performance and increased likelihood of brake failure.

Brake Drums and Rotors

The friction between the brake pads and the drums or rotors can cause these components to warp or become damaged, leading to uneven braking and potential brake failure.

Brake Cables

Over time, the constant tension on the brake cables can cause them to stretch or break, rendering the brakes ineffective.

Duration of Use and Its Impact

The severity of the damage depends on how long the parking brake is engaged while driving.

Short Distances

While driving a few hundred feet with the parking brake on is unlikely to cause significant damage, it is not advisable. The slight overheating and tension can still take a toll on your brakes.

Longer Distances

Driving for several miles with the parking brake engaged can lead to serious issues such as overheating and premature wear of the brakes. In some cases, you might even notice smoke or unusual sounds coming from the brakes.

Recommendations for Safe Driving

If you realize you've been driving with the parking brake on, the best course of action is to stop when it's safe to do so and release the brake immediately. If you experience any unusual sounds or performance issues, it's important to have your vehicle inspected by a professional mechanic.

Extreme Cases

Driving with the parking brake on can generate extreme heat, potentially causing a fire or cracking the brake drums or discs. In modern vehicles with rear discs, the handbrake is not designed to handle the heat of slowing a moving car. In front-wheel drive cars, dragging the rear tires on the ground can lead to additional wear and tear.

Anecdote from the World of High-Performance Cars

One memorable incident involved a friend driving a McLaren F1 supercar on a racetrack. He engaged the parking brake while driving at 100 mph, which resulted in significant damage to the rear brakes and a potential fire hazard. This case underscores the dangers of using the parking brake while driving.

Remember, maintaining proper car maintenance and being aware of your driving habits can help you avoid unwanted and costly repairs. Always ensure your parking brake is disengaged when you're driving to protect your vehicle's braking system.
