Crucial Tips When Diagnosing Brakes Of A Truck

Brakes are an essential part of your truck, but how do you go about diagnosing brakes of a truck? Is it easy or complicated? Your safety and that of other road users rely on the brakes’ effectiveness. Most road accidents result from worn-out brakes or brakes that are in poor condition. However, there are ways you can use to determine if your brakes have problems or not. Here are the tips to rely on when diagnosing brakes of a truck.

Grinding Sounds

Brakes should function in silence. But when your brakes produce a grinding sound is an indication of a problem. It could be the caliper or the metallic part of the brake pads. When such happens, consider checking your brakes as soon as possible.

Squealing Sound

If you apply brakes and hear a high-pitched squealing sound, it indicates that your brake pads are worn out. Such sound can also result from the accumulation of dust on your brake pads. Rust and debris on the rotors are also common causes. It is essential to take your brakes for a check-up whenever you hear such sounds.

Low Break Pressure

The brake pedals should be firm whenever you press them. Such a feeling should increase the more you press the pedals. If you press the brake pedal, but they freely move without resistance, it could indicate leakage on the brake lines. In worse cases, it implies that the entire braking system is failing. 

When driving and your brakes become soft, consider pulling over and calling your mechanic for assistance.

Brake Pedal Vibration

Pedal vibrations are common, especially when your rotors are worn out due to friction or heat. Whenever the brake pedals of your truck become bumpy or vibrate, get your truck checked immediately. This is one of the most crucial things that call for diagnosing brakes of the truck.

Checking the Brake Fluids

When diagnosing brakes, something that every truck owner should always remember is to check on the levels of the brake fluid. It is thus necessary to know the location of the brake fluid reservoir. The brake fluid reservoir has marks that will help you determine the right brake fluid level. 

If the brake fluid is below the marked level, consider replacing it. Apart from the right fluid level, consider using the right brake fluid for your truck. You can do this by checking your truck manual. It is in this book that the manufacturer recommends the right brake fluid for your truck. 

Inspect the Brake Lines & the Master Cylinder

Brake lines and the master cylinder are important parts of the braking system. They play the role of transferring the brake fluid from the reservoir to the brakes. The lines should never have any leakage.

When checking for leakages on the brake lines, pay more attention to the joints between the lines and the cylinder. Also, always remember to check the lines right from the reservoir tank. 

Inspect the Brake Pads

The brake pads take all the heat when braking. They thus have higher chances of wearing out very fast. Consider checking your pads after 6,000 miles. To do this, you have to remove your wheels. 


As a driver, brakes will help you to have complete control to your truck. They should therefore be in perfect working condition. You can achieve this by performing regular check-ups and diagnosis to determine if all the parts are working perfectly. When diagnosing brakes, check all the parts of the braking system.
