Brakes for Semi Trucks – Why They’re Important and How to Maintain Them

Semi trucks are large, heavy vehicles that are designed to haul large loads long distances. Due to their size and weight, semi trucks are equipped with powerful brakes that allow the vehicle to slow down or stop safely and quickly. However, semi truck brakes have certain maintenance requirements in order to work properly and avoid overheating. In this article, we’ll cover why semi truck brakes are so important and how you can take good care of them so they’ll be ready when you need them most.

Differences Between Brakes on Semi Trucks and Cars

The first difference is that semi-trucks have air brakes while most cars have hydraulic brakes. The second difference is that semi-trucks usually have three braking systems- a primary, secondary, and parking brake- while most cars only have two. The third difference is that the brakes on a semi-truck are much larger than those on a car or SUV. This is because the weight of a fully loaded semi-truck can be up to 80,000 pounds, whereas the average car weighs around 4,000 pounds. Finally, the fourth difference is that semi-trucks must stop within a certain distance, called the stopping distance. The stopping distance is the distance it takes for a vehicle to come to a complete stop when traveling at a certain speed.

Good Brakes Extent The Lifespan Of Semi Truck Tires

Truck tires have a shorter lifespan than car tires. This is due to the fact that they are constantly carrying heavy loads and going long distances. Because of this, it’s important to check your brakes frequently and make sure they are in good working condition. Brake pads or brake shoes should be replaced when you notice that there’s less than ¼” of thickness left on them. The same goes for brake drums and rotors as well. A semi truck with faulty brakes can cause accidents as well as contribute to road rage incidents on highways or local roads. That’s why it’s so important to get them checked out regularly by professionals who know what they’re doing!

What Causes Semi Truck Brakes To Fail

Overheating is the primary cause of brake failure. When brakes are used excessively, the friction between the pads and rotors or shoes and drums creates heat. If the brakes are not allowed to cool down, this heat can build up and cause brake fade. When this happens, the brakes will no longer work. Another cause of brake failure is air leaks or miss adjusted brakes. If there is a leak in the system, there will not be enough air pressure to apply the brakes properly. Brake lines can also become corroded over time, which can cause them to leak or rupture.

Brake Maintenance & Inspection Schedule

It is important to maintain your brakes so that they will work properly when you need them. Depending on how often you use your brakes, you should follow a schedule of weekly, monthly, bi-monthly, or quarterly inspections. Here are some things to look for during your inspection:

  • Check the brake pads and brake shoes for wear.
  • Check the rotors and drums for warping and heat cracks.
  • Check for air leaks.
  • Check the brake chambers for damage or corrosion.
  • Check the hoses and lines for leaks or damage.

Check Brake Fluid Regularly

It’s important to check that your brakes are working correctly without pulling or extra effort to apply. At slow speeds in a parking lot or back road apply your foot brake to make sure they are adjusted correctly without pulling to the left or right. Set your parking brake and release your foot brake, if your truck rolls then you need parking brake adjustment or repairs. All slack adjusters will need adjustments and checked for function at least monthly.

Hiring an Expert For Brake Replacement or Repair

It’s important to have brakes that work properly on your semi truck. Not only are they required by law, but they also keep you and other drivers safe on the road. Brakes that aren’t properly maintained can lead to accidents, so it’s important to make sure they are in good condition. Hiring a professional for brake repair and replacement is the best way to ensure that your brakes are in good working order. A professional will be able to properly inspect your brakes and make any necessary repairs or adjustments.
