What Happens If You Drive With Parking Brake? The Risks

The humble parking brake, often overlooked in the symphony of modern vehicles, plays a crucial role in keeping your car stationary and secure. It’s that reassuring lever or button you engage when you park, preventing your vehicle from rolling away on inclines or flat surfaces. But what happens if you accidentally, or perhaps out of curiosity, decide to drive with the parking brake engaged? The answer, unfortunately, is not as straightforward as you might think. Driving with the parking brake on can lead to a cascade of problems, ranging from minor inconveniences to potentially catastrophic consequences. This blog post delves into the intricacies of this seemingly simple question, exploring the mechanics behind the parking brake, the dangers of driving with it engaged, and the potential damage it can inflict on your vehicle.

The Mechanics of the Parking Brake

Understanding how the parking brake works is essential to comprehending the ramifications of driving with it engaged. Unlike the service brake, which uses hydraulic pressure to slow or stop the wheels, the parking brake operates independently, relying on mechanical force.

Types of Parking Brakes

There are two primary types of parking brakes:

  • Cable-operated parking brakes: These systems use cables to connect the parking brake lever to the rear brake calipers or drums. Pulling the lever tightens the cables, applying pressure to the brakes.
  • Hydraulic parking brakes: These systems utilize hydraulic pressure, similar to the service brakes, but with a separate hydraulic circuit dedicated to the parking brake.

Regardless of the type, the parking brake’s primary function is to prevent the vehicle from rolling. It engages by applying pressure to the rear brakes, effectively locking them.

The Dangers of Driving with the Parking Brake Engaged

Driving with the parking brake on can be incredibly dangerous, putting you, your passengers, and other road users at risk. Here’s why: (See Also: How Is the Parking Brake Released? – A Step-by-Step Guide)

Loss of Control

The most immediate and obvious danger is the loss of control. Engaging the parking brake while driving restricts wheel rotation, leading to:

  • Reduced steering responsiveness: The wheels may not turn freely, making it difficult to steer and potentially causing the vehicle to skid or swerve.
  • Increased braking distance: The parking brake applies constant pressure to the rear brakes, hindering your ability to decelerate effectively.

Damage to Your Vehicle

Driving with the parking brake engaged can inflict significant damage on your vehicle’s braking system and other components.

  • Brake wear and tear: The constant pressure on the rear brakes can lead to premature wear and tear on brake pads, rotors, and calipers.
  • Overheating: Excessive friction generated by the engaged parking brake can cause the brakes to overheat, potentially leading to brake failure.
  • Suspension damage: The strain on the suspension system caused by the locked rear wheels can result in damage to springs, shocks, and other components.

Safety Hazards

Beyond the immediate dangers to yourself and your vehicle, driving with the parking brake engaged poses a significant safety hazard to other road users.

  • Increased risk of accidents: The loss of control and reduced braking capability significantly increase the likelihood of collisions.
  • Sudden stops: If the driver is unaware of the engaged parking brake, sudden stops can occur unexpectedly, causing rear-end collisions.

What to Do If You Accidentally Drive with the Parking Brake Engaged

If you realize you’ve accidentally driven with the parking brake engaged, it’s crucial to act quickly and safely.

  1. Pull over immediately: Find a safe location to pull over as soon as possible.
  2. Release the parking brake: Carefully release the parking brake lever or button.
  3. Check for damage: Inspect your vehicle for any signs of damage, such as unusual noises, vibrations, or smoke.
  4. Seek professional help if necessary: If you notice any damage or experience problems with your braking system, have your vehicle inspected by a qualified mechanic immediately.
