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.

Alan Lopez

Family owned where you feel like part of it. King pin, front axel leaf spring and all brakes replacement performed plus alignment( about 3 blocks straight when tested, didn't try more for safety reasons) . No issues at all. Easy access shop for small trucks and trailers surrounded by a huge yard where parking spots available for rent. King pins removed with the proper press no hammer, no heat. Third party financing available. I strongly recommend this business.

Orlando San Jorge

Excellent shop, every work done here is +5 stars, but alignment is from other world, if you make your alignment here, you really get what you are trying to get, maybe the only place in USA where this job is really well done! Nice people, friendly, they took a little longer than other shops, but is just a value added to get the quality they offer in their works. If I have to say it in numbers, I should say: 99.9% of the times you don't have to came back to the shop for the same issue. Nice work guys, keep it that way!

Best part was that they charge me about the same price the other shop tried to charge me for doing nothing.
