The humble emergency brake, often referred to as the parking brake, is a crucial safety feature in every vehicle. It’s designed to prevent your car from rolling when parked on an incline or in situations where the regular brakes might fail. However, driving with the emergency brake engaged is a practice that can quickly turn a routine journey into a perilous situation. While it might seem like a minor oversight, driving with the emergency brake on can have serious consequences for your vehicle and your safety.
This seemingly simple question, “Is it bad to drive with the emergency brake on?” has a resounding answer: yes, it is absolutely bad. Understanding why is essential for every driver. This comprehensive guide will delve into the potential dangers, explore the mechanics behind the emergency brake system, and provide you with the knowledge to avoid this potentially disastrous driving habit.

The Dangers of Driving with the Emergency Brake Engaged
Driving with the emergency brake on can lead to a cascade of problems, putting both you and other road users at risk. Here’s a breakdown of the potential dangers:
1. Reduced Vehicle Control
The primary function of the emergency brake is to lock the rear wheels. While this is effective for stationary vehicles, it drastically reduces your steering control and braking capabilities when driving. Imagine trying to navigate a sharp corner or avoid an unexpected obstacle with your rear wheels locked – the consequences could be catastrophic.
2. Increased Brake Wear and Tear
The emergency brake system is designed for short bursts of use, not sustained application. Driving with the emergency brake engaged puts excessive strain on the brake pads and rotors, leading to premature wear and tear. This can result in costly repairs and potentially compromise your braking system’s effectiveness during critical moments.
3. Tire Damage
The constant friction generated by locked rear wheels can cause excessive heat buildup, leading to tire damage. This can manifest as uneven tread wear, bulges in the tire sidewalls, or even complete tire failure. Driving with the emergency brake on can significantly shorten the lifespan of your tires and create a dangerous situation on the road.
4. Vehicle Vibration and Noise
Driving with the emergency brake engaged will likely result in noticeable vibrations and unusual noises coming from the rear of your vehicle. This can be disconcerting for the driver and passengers and may indicate underlying damage to the braking system or other components.
Understanding the Emergency Brake System
Before we delve into the “why” of avoiding driving with the emergency brake on, it’s crucial to understand how this system works. The emergency brake, also known as the parking brake, typically operates independently of the regular braking system. It utilizes a separate set of cables and mechanisms to apply pressure to the rear brake drums or discs. (See Also: What Are Brake Pads Made Of? – The Inside Scoop)
When you engage the emergency brake, these cables pull on the brake shoes or pads, forcing them against the drums or discs, effectively locking the rear wheels. This provides the necessary stopping force to prevent the vehicle from rolling when parked on an incline or in situations where the regular brakes might fail.
Why Driving with the Emergency Brake On is a Bad Idea
Now that we understand the mechanics of the emergency brake system, it becomes clear why driving with it engaged is a bad idea. The emergency brake is designed for short bursts of use, not sustained application. Driving with it on puts excessive strain on the brake system, leading to premature wear and tear, potential damage to the vehicle, and compromised safety.
Here’s a closer look at the reasons why driving with the emergency brake on is detrimental:
1. Increased Brake Pad Wear
The emergency brake pads are designed to handle short bursts of force, not the continuous friction generated by driving. Driving with the emergency brake on will cause these pads to wear down much faster than normal, potentially leading to brake failure.
2. Brake Rotor Damage
The rotors, which are the metal discs that the brake pads press against, can also suffer damage from continuous friction. Driving with the emergency brake on can cause warping or scoring of the rotors, affecting braking performance and potentially leading to vibrations.
3. Transmission Strain
The emergency brake’s constant engagement can put strain on the transmission, as it has to work harder to overcome the resistance created by the locked rear wheels. This can lead to premature wear and tear on the transmission components.
4. Fuel Efficiency Loss
Driving with the emergency brake on creates additional drag, forcing the engine to work harder and consume more fuel. This can result in a noticeable decrease in fuel efficiency. (See Also: When to Replace Brake? Know The Signs)
Alternatives to Driving with the Emergency Brake On
If you find yourself in a situation where you need to apply extra braking force, there are safer and more effective alternatives to using the emergency brake. Here are some options:
1. Use the Regular Brakes
The regular braking system is designed to handle most driving situations. Apply firm and gradual pressure to the brake pedal to achieve the desired braking effect.
2. Downshifting
In manual transmission vehicles, downshifting can help to slow the vehicle down without relying solely on the brakes. This utilizes engine braking, which can be more effective in certain situations.
3. Use Engine Braking
In automatic transmission vehicles, you can use engine braking by gently releasing the accelerator pedal and allowing the engine to slow the vehicle down. This can help to reduce brake wear and improve fuel efficiency.
Is it Bad to Drive with Emergency Brake on? FAQs
What happens if I drive with the emergency brake on?
Driving with the emergency brake on can cause several problems, including reduced vehicle control, increased brake wear and tear, tire damage, vehicle vibration and noise, and potential transmission strain. It’s crucial to avoid driving with the emergency brake engaged.
Can I drive with the emergency brake slightly on?
No, even slightly engaging the emergency brake while driving is dangerous. It will still put unnecessary stress on your brakes and affect your vehicle’s handling.
Why does my car shake when I drive with the emergency brake on?
Shaking while driving with the emergency brake on is a sign that your rear wheels are locked, causing excessive friction and vibrations. This can damage your brakes and tires. (See Also: When You Press on the Brake Pedal? What Happens Next)
How do I know if my emergency brake is engaged while driving?
You’ll likely feel a noticeable pulling sensation towards the rear of the vehicle and experience reduced steering control. You may also hear unusual noises coming from the rear brakes.
What should I do if I accidentally engage the emergency brake while driving?
Immediately release the emergency brake lever. If you experience any unusual handling or braking issues, pull over to a safe location and inspect your brakes.
Conclusion
Driving with the emergency brake engaged is a dangerous practice that can have serious consequences for your vehicle and your safety. Understanding the mechanics of the emergency brake system and the potential dangers associated with driving with it on is essential for every driver. Always remember to disengage the emergency brake before starting your journey and rely on the regular braking system for safe and effective stopping power.
By following these guidelines and avoiding the temptation to drive with the emergency brake on, you can ensure a safer and more enjoyable driving experience. Remember, your safety and the safety of others on the road are paramount.
