Tractor Brakes
Tractor brakes are an important safety feature on many tractors, especially the more expensive models. However, some newer models do not include this important safety feature, so it is important to have a reliable trailer brake system as well. Safety sensors in these vehicles are located in the drive train control module, or axle, and they sense any movement or abnormal speed. When there is a problem, the brakes are applied without delay, which helps to bring the vehicle to a complete stop before the wheels begin to lock. The brakes can be manually applied if they are equipped with a clutch, but in most cases they must be activated by the driver. Most modern tractors include front and rear hydraulic brakes, although there may be one or two selectable side brakes that are included with every vehicle.
There are three types of truck and tractor brakes: drum brakes, line drums, and rotors with cylinder locks. Drum brakes are a type of self-contained braking system that consists of drum seals, pressure drums, and piston rings. They are the oldest type and were originally developed for tractors and other large scale vehicle applications. Line drums have been around for decades and are similar to drum brakes, except they are not self contained. Instead, they are powered by a counterweight that is usually made from cast iron.
Rotors with cylinder locks are designed to operate in a closed loop. This means that they have a locking mechanism that helps keep the wheels from locking while the brake is being applied. These are the most commonly used on heavy duty vehicles and trailers, but they are also available on many newer model line tractors and light trucks. Tractor trailer brakes are essential to the overall security of your cargo, so be sure to have the right equipment installed on your vehicle.
