How to Know When to Replace Car Brake Pads?
1 Answers
Methods to determine if car brake pads need replacement: 1. Listen for abnormal noises from the brake pads, as this indicates replacement is needed; 2. Check the thickness - replace when the brake pad thickness is approximately 0.5cm; 3. Observe the indicator marks. Each brake pad has raised indicator marks on both sides, with a thickness of about 2-3mm, which represents the minimum wear limit. If the brake pad thickness is level with these marks, immediate replacement is required. Brake pads refer to the friction materials fixed on the rotating brake drum or disc connected to the wheel. The friction linings and blocks bear external pressure to generate friction, thereby achieving vehicle deceleration. Based on material composition, car brake pads can be categorized into resin-based brake materials, powder metallurgy brake materials, carbon composite brake materials, and ceramic-based brake materials.
