Truck brake pad self-inspection should focus on wear level, working condition, and related components. Timely detection of potential problems can prevent brake failure and ensure driving safety.
Visual inspection of wear thickness is fundamental. Remove the wheel or check through the wheel hub inspection hole. The remaining thickness of the brake pad friction material should be ≥3mm. If it is lower than this value, the brake pads must be replaced immediately. Simultaneously check if the brake pads are worn evenly. If one side is severely worn, it may indicate a stuck caliper guide pin, requiring simultaneous repair.
Pay attention to abnormal braking behavior. If abnormal noises occur during braking (such as metallic friction or screeching), it is highly likely that the brake pads are excessively worn or contain impurities. If the brake pedal feels soft, travel is longer, or the vehicle veers to one side or the braking distance increases significantly, check the fit between the brake pads and the brake disc, and whether there are leaks in the braking system.
Checking the condition of related components is also crucial. Check the truck brake pad retaining pins and springs for looseness or deformation, ensuring the brake pads are securely installed. Simultaneously inspect the surface of the brake disc. Obvious grooves, cracks, or uneven wear will accelerate brake pad wear and require immediate attention.
Consider the usage scenario to aid in judgment. Trucks that frequently travel in mountainous areas or carry heavy loads experience faster brake pad wear, requiring shorter self-inspection cycles. If brake pads have been used for more than 80,000 kilometers, even if there are no obvious abnormalities in appearance, it is recommended to have them professionally inspected to avoid affecting braking performance due to material fatigue.
