Semi trucks feature air brakes that use compressed air to slow down. By way of pressurized air, the brake shoe is brought to the brake drum, creating the friction needed to slow down the big rig. When hauling heavy loads across vast distances and steep inclines, it’s crucial that your air braking system is working flawlessly. As soon as you suspect trouble with your semi truck’s brakes, you’ll want to have an expert technician take a look. At Blue Gray Towing, we specialize in semi truck brake repair in the greater Hagerstown, MD area. Here’s a look at five common types of air brake trouble.

Pressure Accumulates Too Slowly

If pressure is building up too slowly, then you’ve got a sign of trouble with the compressor. This could make it harder for the truck to safely slow down. A healthy compressor plays a crucial role in proper deceleration. 

Loses Pressure Too Fast

Pressure may drop overly fast if there’s a problem with the valves that control the airflow out of the reservoir. This could then create significant stress on the compressor. 

Water/Oil Getting into Air Reservoir

Air braking systems have air dryers that remove water/oil from the air before it can get into the reservoir, which helps to stop corrosion from occurring. But if there’s an issue with an air dryer cartridge, then water may find its way into the reservoir.

Brake Shoe Is Stuck

When a brake shoe is stuck, you may still be able to bring your truck to a stop, but then when you try to accelerate, your truck may struggle to speed up.

Misaligned Brake Shoes 

It’s best if brake shoes wear down in an even manner. When one brake shoe becomes thinner, it is liable to then wear down even faster. Consequently, you may notice scraping and squealing noises.
