Here are 10 Things & Tips for Truck Brake System Maintenance and Repair

1. The brakes need servicing

Brake maintenance is one of the most important elements of vehicle care, yet it often goes overlooked, especially regarding trucks. Although there are no strict guidelines on when a truck’s brakes should be serviced, all brakes must be inspected, adjusted, and serviced at least once or twice yearly.

This is even more important if your truck is used in harsh road conditions or has a driving style that puts extra stress on the brakes.

Regular brake service and inspection can help identify any issues with your brakes before they lead to unsafe driving conditions. An experienced truck repair professional will be able to evaluate and assess the condition of your truck’s brake system, from inspecting brake lines and hoses for wear and tear to replacing worn-out parts such as pads, rotors, or calipers.

They may also recommend additional modifications like upgraded brake pads for improved braking performance. Keeping up with regular brake service is essential for an unaffected driving experience and ensuring the safety of everyone sharing the roads with you.

2. Keep Your Brake Fluid Fresh with Regular Flushing

 It acts as a hydraulic medium over which pressure is transferred, causing your brakes to function properly when you press down on the brake pedal. However, unfortunately, over time, this valuable fluid can become contaminated with various particles from the atmosphere, leading to a decrease in its boiling point. Eventually, this will hurt the performance of your brakes.

Also, when moisture gets into the brake fluid, it causes corrosion to the master and wheel cylinders, increasing wear and tear and even leading to complete brake failure in extreme cases. To keep your brakes functioning smoothly and safely for longer, you must flush out your brakes regularly. This should be done more frequently if signs of low-quality fluid, such as cloudy or milky-looking fluid, appear when you inspect it.

By performing regular brake fluid flushes, you will ensure that there is always fresh, high-quality brake fluid in your system so that you can get solid and reliable braking performance every time you drive.

3. Check Your Brake Lines and Hoses for Wear and Tear

Your brake system is powered by pressurized brake fluid, so it’s essential to regularly check your truck’s brake lines and hoses for wear and tear. Frayed or damaged brake lines can decrease the pressure of your brakes, meaning that you won’t have as much control over your vehicle when you press down on the brake pedal.

Inspecting and replacing brake lines and hoses as needed is a straightforward process that a qualified mechanic can complete quickly and efficiently. This will also help prevent leaking brake fluid, which could lead to significantly reduced braking performance.

4. Replace Worn-Out Parts

Over time, the various parts of your truck’s brake system can become worn out. This is especially true for pads, rotors, and calipers, all subject to wear due to friction as you press down on the brake pedal. When these components become worn out, it can interfere with your truck’s braking performance, leading to diminished control and decreased overall safety.

To ensure the best and safest performance of your truck, you should inspect these parts regularly to see if they need replacement. If they do, replacing them with new, high-quality components is important as soon as possible. This is especially true for rotors and calipers, vital for proper braking.

5. Rotor Inspection Is Crucial

When your truck is driving along, the rotors play an important role in keeping you safe. The rotors are round pieces of metal that the brake pads clamp on when you step on the brakes. It’s essential to keep them working at peak performance by inspecting and potentially replacing them over time.

While rotors can last up to 70,000 miles, it never hurts to double-check their condition for any signs of wear and tear, such as rattling, shaking, or wobbling while braking. When inspecting your vehicle’s brakes, it’s a good idea to check for grooves or stress cracks on the rotors.

If they need replacement, always replace both sides of the front or rear rotors in pairs; this ensures that each side wears evenly during use. This is important because if one rotor is weaker, it can cause your vehicle to pull in one direction while applying brake pressure. Regularly scheduled brake maintenance will help ensure your truck’s safety and extend its lifespan with proper care and attention to inspecting its rotors.

6. Learn the Difference First

Spec’ing brakes come down to choosing between hydraulic, air disc, and exhaust. Understanding the differences between these three brake types is essential before deciding which one to spec. Alicia Wong, Director of Brakes NA at Meritor, suggests evaluating the application of the vehicles when considering hydraulic brakes, as well as looking at widths and liner grades that provide different levels of braking and life requirements.

Additionally, selecting brakes with flexible mounting configurations will make packaging the vehicle easier, while fast shoe replacement designs help minimize repair and service time.

For air brakes, Wong recommends considering separate applications such as those requiring superior stopping performance or trucks that may run hotter due to severe performance or increased weight.

Generally speaking, using air disc brakes can enhance performance while reducing brake drag, plus they have an increased service life with minimal repair time needed. Ultimately, understanding the key differences between hydraulic, air disc, and exhaust brakes is important for fleets to decide which brake type is necessary for their unique situation.

7. Adjustment and Testing

After thoroughly inspecting and replacing necessary components, it’s critical to adjust the brakes for optimal safety and performance. This task requires special tools and knowledge about how to adjust them so that they work properly and correctly.

In addition, testing the brakes is essential to ensure they work safely and effectively. This involves taking your truck out on a test drive and testing them in different conditions to ensure they function properly.

Overall, it’s important to routinely inspect and maintain your truck’s brake system to ensure its safety and performance. Be sure to check the various components of the system regularly, replacing worn parts as necessary. Finally, adjust and test the brakes after any repairs or replacements to ensure they work properly.

8. Regularly Scheduling Maintenance

Maintaining your truck’s brakes is important to ensure they stay in top working condition. To help keep your rotors in peak performance, you should have them serviced every 12,000 miles or as the manufacturer requires. During servicing, a technician will inspect the brake pads and rotors for signs of wear or damage. If any issues are found, they will be replaced as needed.

Additionally, the technician can adjust the brakes to ensure they are working properly. Scheduling regular maintenance and inspections will help keep your truck safe on the road and reduce any potential repair costs in the future.

9. Common Brake System Problems

No matter how well you maintain your truck’s brake system, problems that need to be addressed can still arise. Common issues include brake pads wearing out prematurely, rotors becoming warped or damaged, brakes squealing when used, and calipers sticking.

If any of these problems are encountered, it is important to address them quickly to ensure your truck is safe to drive. Additionally, having a professional inspect and repair the system as needed is important.
