Common Signs Your Semi Truck Needs Brake Repair

Common Signs Your Semi Truck Needs Brake Repair

Common Signs Your Semi Truck Needs Brake RepairSemi trucks and the trailers they connect to are outfitted with air brake systems, which rely on air instead of hydraulic fluid, as your daily driver does. This means that the air brake system can never run out of fluid or become inoperable due to a brake fluid leak. This allows for your truck's braking system to be more reliable than a fluid based system, and also easily connected to one or more trailers. However, even a healthy brake system in your truck is under a lot of pressure due to the weight of your truck. So while brake trouble with any vehicle is dangerous, when it comes to your truck, that danger can increase exponentially. If you encounter any of the following issues with your air brake system, be sure to contact a reputable truck repair shop to have your semi properly serviced before it's too late.

Grinding or Squealing

If you encounter a squealing noise when you apply the brakes it means that your brake pads need to be replaced, a service that generally needs to be completed every 50,000 miles. A more mechanical grinding noise indicates that the pads have worn so badly that the metal calipers are grinding against your rotors. If you don't have repairs completed immediately damage to your rotors will occur.


A vibrating brake pedal, cab or whole truck can indicate warped rotors. The rotors are what the bads rub against to create the friction that slows your truck. Warping is a common issue, especially when constantly hauling heavy loads.


When you hit the brakes your truck should continue in a straight line. If it feels like your truck jerks or pulls left or right when you hit the brakes then there may be uneven brake pad wear, a problem with an air brake hose or other faulty components. Additionally, this may indicate your truck's wheel alignment is off.

Soft Brake Pedal

If the brake pedal is easy to push to the floor or not rests closer to the floor, it is probable that your brake pads are heavily worn. However, this could also indicate a leak in an air brake line.
