The open road beckons, promising adventure and freedom. But behind the thrill of the drive lies a critical responsibility: ensuring your safety and the safety of others. One of the most fundamental aspects of safe driving is understanding when and how to use your vehicle’s emergency brake. While it might seem like a simple mechanism, the emergency brake, also known as the parking brake, plays a crucial role in preventing accidents and maintaining control in unexpected situations.
This seemingly straightforward tool can be a lifesaver in emergencies, but its misuse can lead to dangerous consequences. This comprehensive guide will delve into the intricacies of the emergency brake, exploring its functions, proper usage, and the situations where it becomes an indispensable safety measure.

Understanding the Emergency Brake
The emergency brake, often found as a lever or pedal in the driver’s compartment, is a vital safety feature designed to bring your vehicle to a complete stop in an emergency. Unlike the regular brake pedal, which relies on hydraulic pressure to apply friction to the brake pads, the emergency brake engages a separate mechanical system that directly applies force to the wheels. This provides an additional level of braking power when the regular brakes fail or when you need to hold the vehicle stationary on an incline.
How the Emergency Brake Works
The exact mechanism of the emergency brake varies depending on the vehicle model, but the general principle remains the same. Most vehicles utilize a cable system that connects the brake lever or pedal to a set of brake shoes or pads located within the rear wheels. When you engage the emergency brake, the cable tightens, forcing the brake shoes or pads against the brake drums or rotors, effectively halting the rotation of the wheels.
Types of Emergency Brakes
There are two primary types of emergency brakes:
- Cable-operated brakes: These are the most common type, using a cable to transmit force from the lever or pedal to the rear wheels.
- Hydraulic-operated brakes: Less common, these systems use hydraulic pressure to engage the brakes, similar to the regular braking system.
When to Use the Emergency Brake
While the emergency brake is primarily designed for emergency situations, it also has several important everyday uses.
Parking on an Incline
The most common use of the emergency brake is to prevent your vehicle from rolling when parked on an incline. Engage the emergency brake firmly before exiting the vehicle to ensure it remains stationary.
Emergency Braking
If your regular brakes fail, the emergency brake can provide a last resort to slow down or stop your vehicle. However, remember that the emergency brake is not intended for prolonged use and can cause damage to your wheels and brakes if applied too forcefully or for extended periods.

Towing
Some vehicles require the emergency brake to be engaged when being towed. Consult your owner’s manual for specific instructions regarding towing procedures.
Preventing Rollback
When starting on a steep incline, engaging the emergency brake briefly can help prevent rollback. Release the brake gradually as you begin to accelerate.
Proper Usage and Maintenance
Using the emergency brake correctly is crucial for both safety and longevity.
Engaging and Disengaging the Brake
Always engage the emergency brake firmly and ensure it is fully locked before parking on an incline or in any situation where you need to prevent the vehicle from moving. When disengaging the brake, release it slowly and smoothly to avoid sudden jolts or damage to the brake system.
Adjusting the Brake
Over time, the emergency brake may require adjustment. If you notice that the brake is not engaging firmly or that the vehicle rolls slightly when parked on an incline, consult your owner’s manual or a qualified mechanic for adjustment instructions.
Regular Inspection
Periodically inspect the emergency brake system for any signs of wear or damage, such as frayed cables, worn brake shoes, or leaking hydraulic fluid. Address any issues promptly to ensure the brake remains functional. (See Also: What Does Cover The Brake Mean? In Simple Terms)
Potential Dangers of Improper Use
While the emergency brake is a valuable safety tool, its improper use can lead to dangerous situations.
Wheel Lockup
Applying the emergency brake too forcefully can cause the wheels to lock up, leading to a loss of control and potentially causing an accident.
Brake Fade
Prolonged use of the emergency brake can overheat the brake system, leading to brake fade, a condition where the brakes become less effective.
Damage to Brake Components
Excessive or improper use of the emergency brake can damage brake components, such as brake shoes, drums, or rotors, requiring costly repairs.
When Should You Put the Emergency Brake on?
To summarize, the emergency brake is a crucial safety device that should be used judiciously. Here’s a breakdown of when to engage the emergency brake:
- Parking on an incline: Always engage the emergency brake firmly when parking on a hill to prevent the vehicle from rolling.
- Emergency braking: If your regular brakes fail, use the emergency brake as a last resort to slow down or stop the vehicle.
- Towing: Some vehicles require the emergency brake to be engaged when being towed.
- Preventing rollback: Briefly engage the emergency brake when starting on a steep incline to prevent rollback.
Frequently Asked Questions
When Should You Put the Emergency Brake on?
What happens if I leave the emergency brake on while driving?
Leaving the emergency brake engaged while driving can cause significant damage to your vehicle. It will put excessive strain on your brakes, potentially leading to overheating, brake fade, and even complete brake failure. It can also cause your wheels to lock up, leading to a loss of control and a potential accident.
Can I use the emergency brake to slow down on a long downhill?
While the emergency brake can help slow down, it’s not designed for prolonged use. Using it excessively on a downhill can cause overheating and damage to your brake system. It’s best to rely on your regular brakes and downshifting to control your speed on a long downhill. (See Also: How to Check Brake Fluid Chevy Impala? Easy Steps)
How often should I adjust my emergency brake?
The frequency of emergency brake adjustments depends on your driving habits and the condition of your vehicle. It’s generally recommended to have your emergency brake inspected and adjusted at least once a year or as needed if you notice any signs of wear or malfunction.
What are the signs that my emergency brake needs adjusting?
Some common signs that your emergency brake needs adjusting include:
- The vehicle rolls slightly when parked on an incline.
- The brake lever or pedal feels loose or spongy.
- You hear grinding or squeaking noises when engaging or disengaging the brake.
Is it safe to use the emergency brake on dry pavement?
While the emergency brake is designed to work on various surfaces, using it on dry pavement can be dangerous. It can cause your wheels to lock up, leading to a loss of control. It’s best to avoid using the emergency brake on dry pavement unless absolutely necessary in an emergency situation.
