Truck Brake Pad wear is crucial to driving safety. Promptly replacing excessively worn brake pads can effectively prevent brake failure. Thickness is a key indicator for determining whether brake pads need replacement. New Truck Brake Pads typically have a thickness of 15-20 mm, with slight variations between models. When the friction material wears down to just 3 mm, replacement is essential. Some brake pads have metal warning plates. When wear reaches a critical point, the plates come into contact with the brake disc, producing a sharp, grinding sound. At this point, the remaining thickness of the brake pad is often less than 2 mm. Use a vernier caliper to measure only the friction material portion.
Also, unusual sounds and feel are important warning signs. Even if the thickness hasn't reached the critical limit, a persistent, harsh sound during braking, a soft brake pedal, or increased braking distances could indicate uneven wear or internal structural damage. Stop the vehicle immediately and inspect it. If necessary, visit a professional repair shop to have the Truck Brake Pads inspected using specialized equipment. Don't let minor issues lead to safety hazards.
