Vehicle safety is a critical aspect for getting from point A to point B safely. Understanding the brake system and its components, such as the spring brake, is necessary for proper vehicle maintenance and smooth operation. Spring brakes are used in large vehicles and heavy machinery, but understanding what they are and how they work is important for all drivers, regardless of the size of their vehicle.

What are Spring Brakes?

Spring brakes (also known as emergency brakes) are critical components of the brake system in larger vehicles, such as semi-trucks and buses. The spring brake is intended to stop the vehicle without air in the air brake system and it is typically used as a parking brake. They are typically made of wire leather-coated steel and are mounted at the end of the axle. A lever and a cable are used to mechanically activate the brake and press it onto the axle’s drum.

Is the Spring Brake the Parking Brake?

The spring brake is typically used as a parking brake, but it also works as an emergency brake when there is no air in the air brake system. It uses the tension in the brake springs and a lever and cable to press it onto the axle’s drum. The spring brake also works to keep the vehicle from creeping ahead when it’s parked, even on an incline.

What Should You Never Do When the Spring Brakes are On?

When your spring brakes are engaged, it is important to never drive your vehicle because it will not be able to stop and the brakes could fall off coming down the road. Driving the vehicle with the spring brakes on can result in the brakes wearing down and becoming weakened, leading to potential wheels locking, loss of speed control and serious damage to the vehicle and anyone inside. It is best to never drive your vehicle with the spring brakes engaged, as it could result in serious injury and damage.

How long do Spring Brakes Last?

Spring brakes typically last anywhere from 2,000 to 2,500 miles, depending on their type and the material they are made of. They should last longer if they are well maintained and if they are not overextended. The brake linings and supporting components should be regularly checked and inspected. It is also important to make sure they are properly adjusted and that they are not allowed to get too hot.

Conclusion

Understanding spring brakes and their purpose is an important part of maintaining your vehicle and making sure that you and your passengers stay safe. It is important to understand the purpose of the spring brakes and make sure that they are regularly inspected and adjusted to ensure that they are functioning properly. Always make sure that your spring brakes are properly engaged and never drive your vehicle with them in use.
