How often should brake pads be replaced?
2 Answers
Car brake pads should not be replaced based on a fixed mileage. Generally, front brake pads should be replaced at approximately 30,000 kilometers, while rear brake pads should be replaced at around 80,000 kilometers. However, since everyone's driving habits differ and each vehicle's braking system varies, the replacement time should be determined based on the degree of wear. Nevertheless, it is best not to exceed these mileage limits. Brake pads typically consist of a steel plate, an adhesive heat insulation layer, and a friction block. Below are the relevant details: 1. The steel plate undergoes coating to prevent rust. The coating process is monitored using an SMT4 temperature tracker to ensure the temperature distribution during coating meets quality standards. 2. The heat insulation layer is made of non-conductive materials to provide thermal insulation. 3. The friction block is composed of friction materials and adhesives. When braking, it is pressed against the brake disc or drum to generate friction, thereby achieving the purpose of slowing down or stopping the vehicle.
A friend who drives a lot once shared that there's no fixed standard for how often brake pads need replacing—it typically ranges between 30,000 to 70,000 kilometers, depending on your driving habits. For someone like me who commutes daily in the city with frequent traffic jams and sudden braking, they usually need replacing around 50,000 kilometers. If you drive smoothly in the suburbs, you might stretch it to over 60,000 kilometers. The key is learning to self-check: if you hear a sharp squealing noise or feel the brakes aren’t as responsive, head to the repair shop immediately. During maintenance, mechanics also measure pad thickness with calipers—if it’s under 4mm, replace them without hesitation. Early replacement protects the brake rotors, saving money and ensuring safety. Remember, driving habits matter most—avoid slamming the brakes or aggressive starts, and smooth operation extends their lifespan.
