One of the most important safety features on a semi-truck is its brakes. Proper maintenance and regular checks are crucial to ensure the brakes are functioning correctly and can safely stop the vehicle when needed. In this blog, we will discuss how to adjust brakes on a semi, how to check the brakes on a semi, and how to check disc brakes on semi-truck.
How to Adjust Brakes on a Semi
Adjusting brakes on a semi can be a complex and technical task that should be done by a trained and experienced professional. However, there are some general guidelines that can help you understand the process. The first step in adjusting the brakes is to ensure that the vehicle is parked on a flat and level surface. Next, release the parking brake and chock the wheels to prevent the vehicle from moving.
To adjust drum brakes, you will need to access the brake drum by removing the wheel and tire. Once the drum is exposed, you can adjust the brakes by turning the adjustment screw located on the brake assembly. Turning the screw clockwise will tighten the brakes, while turning it counterclockwise will loosen them. It is important to adjust the brakes evenly on both sides to ensure the vehicle stops straight.
How to Check Brakes on a Semi
Checking the brakes on a semi is an essential part of routine maintenance to ensure they are in proper working condition. To check the brakes, you can perform a visual inspection of the brake components, including the brake pads, drums, and calipers. Look for any signs of wear or damage, such as uneven wear on the brake pads or leaking brake fluid. It is also important to check the brake lines for any signs of corrosion or leaks.
Another important aspect of checking the brakes on a semi is to test the braking system while driving. When driving the vehicle, pay attention to any unusual noises or vibrations when applying the brakes. If you notice any issues, such as a squealing noise or a pulsating brake pedal, it may indicate a problem with the brakes that needs to be addressed.
How to Check Disc Brakes on Semi Truck
Checking disc brakes on semi-truck is similar to checking drum brakes, but there are some key differences. To inspect disc brakes, you will need to remove the wheel and tire to access the brake rotor. Inspect the rotor for any signs of wear, such as grooves or scoring, which can indicate the brakes need to be replaced. Next, check the brake pads for wear. It’s recommended to ensure they have at least 1/4 inch of pad remaining.
