At Lone Star Tire & Diesel Service in Dallas, Texas, we understand the importance of the braking system in heavy-duty trucks. With their high weight and large size, these vehicles require powerful braking systems to stop effectively. Regular maintenance is essential to ensure the safety of the driver and those on the road around them. We offer certified brake drum repair services to keep your heavy-duty truck's braking system operating at peak performance.
Understanding How Air Brakes Function
Air brakes are the most common type of braking system in heavy-duty trucks. Air brakes use compressed air to create the force required to stop the vehicle. This type of braking system is powerful, reliable, and provides consistent stopping power. Air brakes have multiple components, including air compressors, air tanks, air lines, and brake chambers. The air compressor compresses air into the air tanks, which store the compressed air until it is needed to stop the vehicle. When the brake pedal is pressed, the compressed air is released from the air tanks and directed to the brake chambers, which push the brake shoes or pads against the brake drums or rotors, creating friction and stopping the vehicle.
Signs of Brake Drum Failure
The brake drums on heavy-duty trucks are a critical part of the braking system. Over time, these drums can become worn, cracked, or warped, reducing their ability to effectively stop the vehicle.
Faulty Air Brake Unloader Valve
One of the many valves involved in a truck's air brake system is the unloader valve. Its primary responsibility is to release trapped air from the air compression chamber, making the compressor easier to start. However, excess carbon can cause malfunctions in the unloader valve, leading to air compressor difficulty starting. This is particularly relevant for trucks with EGR systems. A-Z Truck & Trailer Repair provides a solution to the problem through the application of carburetor cleaner and compressed air, or the option for valve replacement.
Worn Brake Pads
In heavy-duty trucks equipped with drum brake systems, friction driven by compressed air is the primary means of braking. These systems' extensive use of friction can cause parts to wear down, necessitating greater maintenance. The brake pads, compressed against the system's brake drums to apply friction and stop the vehicle, are one of the critical components of drum brakes. The friction naturally leads to pad wear and eventual replacement, indicated by brake adjustor issues and overall poor braking performance. The best time to replace brake pads is when they are down to a quarter-inch thickness.
