The frequency at which brake linings need to be replaced depends on several factors, including your driving habits, the weight of your truck, and the type of brake lining material.

As a general rule, it is recommended to have your brake linings inspected by a qualified mechanic every 10,000 to 12,000 miles. During the inspection, the mechanic will check the thickness of the brake lining material and determine if it needs to be replaced.

In addition to regular inspections, you should also pay attention to any signs of wear or issues with your braking system. Some common signs that your brake linings may need to be replaced include squeaking or grinding noises when you apply the brakes, reduced brake responsiveness, or a vibrating brake pedal.

It is important to address any issues with your braking system promptly, as worn brake linings can compromise your vehicle's safety and increase the risk of accidents. If you notice any problems with your brakes, you should have them inspected by a qualified mechanic as soon as possible.
