Airline Brakes Chamber

Air brake chambers are round metal containers, located at each wheel, where compressed air is converted into mechanical force to apply the brakes and stop the vehicle. There are two kinds of air brake chambers - service and spring brake chambers. A service brake chamber contains a flexible rubber disc called a diaphragm, a metal rod called a pushrod and a return spring. When you press the brake pedal, compressed air fills the service brake chamber, causing the diaphragm to move and push out the pushrod to apply the brakes (Diagram 3-1). When air pressure is released, the pushrod is returned to its original position by the spring inside the chamber (Diagram 3-2).

The pushrod and a lever - called a slack adjuster - link the brake chamber to the brake assembly (which contains the brake drum or disc). When you press the brake pedal, the pushrod extends farther from the brake chamber, moving the slack adjuster forward. The motion of the slack adjuster transfers to the brake assembly, causing the brake shoes or pads to make contact with the brake drum or disc.

Why you should have an Electrical System Analysis electrical diagnosticsA steady supply of current is crucial to operating the highly sophisticated electronics in today’s vehicles. Lack of current or fluctuations in the supply of current can:

cause the “Check Engine” light to come on cause poor performance or stalling result in malfunctions of the computers that operate your vehicle’s climate control, ride control and brakes.

Fleet Maintenance

Fleet maintenance is the process of keeping all of your organization’s vehicles in good working order so that they can be used safely and effectively. A good fleet maintenance program will focus on preventive maintenance so that issues never occur during the use of the vehicle

A fleet maintenance program also serves to lower the costs of repairs. For example, maintaining a vehicle’s engine might be expensive in the short term, but not so expensive as having to replace the entire engine (or the entire vehicle). Just like you shouldn’t neglect to change your personal car’s oil, you shouldn’t neglect your fleet either.

5th Wheel Repair

5th wheel is the only connection between the truck and trailer, thus it is extremely important to keep the 5th wheel properly inspected, adjusted and lubricated at all times.

A large portion of grease that escapes from the top plate, ends up in the locking mechanism. As the truck and trailer traveling down the road, the grease will attract road dirt and dust. That mixture will end up stiffing the lock mechanism. Routine cleaning and/or power washing “the underside” of the top plate, will keep the locking mechanism free and easy to operate. Many 5th wheels are positioned in one spot and do not slide back or forth. Lack of routine sliding mechanism maintenance and inspection might cause slide cylinder seizure, release pins seizure resulting in costly repairs Depending on the condition of the 5th wheel top plate and locking mechanism, the 5th wheel can be either rebuilt or replaced Most 5th wheel problems are caused by lack of proper maintenance, therefore this mechanism requires regular check ups and inspection
