A dual air brake system is a braking system that consists of two separate air brake systems, with their own sets of hoses, lines and tanks that use the same set of brake controls. Often, dual air brake systems correspond to different axles on large vehicles. In this type of setup, one set of equipment is called the primary system, and the other setup is the secondary system.Know More
Air brakes are actually created using three different types of braking systems: service brakes, parking brakes and emergency brakes. In an air brake design, compressed air is used on all of these brakes to transfer pressure and ultimately give the vehicle its stopping power. Because of the amount of compressed air used, air braking systems require their own air tanks and must be maintained regularly to make sure they still function well.
Heavy-duty vehicles, like buses and trucks, often have two different air braking systems. Because they are so large, the use of a dual air brake system allows for the pressure transmission needed to stop these large vehicles to spread efficiently, according to the California DMV. Usually, each braking system corresponds to a different set of front or rear axles. These types of air braking systems need to build up some pressure before they are able to function.Learn more about Brakes
Perform an air brake test by checking the emergency brake, cut-in and cut-out limitations, static air levels, applied air levels and low-air alarms. You should also inspect the braking system for any obvious damage and check to ensure that the push rod moves between 1.5 and 2 inches when engaged.Full Answer >
The first step to troubleshooting an anti-lock brake system is checking the fuse that manages the brakes. If the fuse is functional, check the harness of the ABS controller for signs of corrosion. Then check the wheel sensors. If those are in order, you might need a new ABS controller.Full Answer >
While disc brakes tend to last anywhere from 30,000 to 50,000 miles, the length of time brake rotors typically last depends on several different factors. These factors include how often the brakes are applied, how hard they are applied, the weight of the vehicle and how often the brakes have been serviced.Full Answer >
During a hard stop, if the brakes remain engaged with hard steady pressure for too long, the brake pads can overheat and cause the moving parts of the braking system to lock in position. Brake lock up is a particular danger on wet and slippery roads. Once the braking system locks up, much of the vehicle's control and stopping ability is compromised.Full Answer >
