How long does it take to break in new car brake pads?

The break-in period varies depending on the type of brake pads installed. Here is relevant information about brake pads: 1. Introduction: Brake pads (also called brake linings) are the most critical safety components in a car's braking system. They play a decisive role in braking performance. Brake linings generally consist of steel plates, adhesive heat insulation layers, and friction blocks. The steel plates are coated for rust prevention, with the coating process monitored by SMT-4 furnace temperature tracking instruments to ensure quality by detecting temperature distribution. 2. Classification: Brake pads are mainly divided into the following categories: metallic brake pads and carbon-ceramic brake pads. Metallic brake pads are further classified into low-metallic and semi-metallic types, with ceramic brake pads categorized under low-metallic. Carbon-ceramic brake pads are used in conjunction with carbon-ceramic brake discs.
As someone who frequently works on my own car, I believe that newly replaced brake pads require a break-in period of around 300 to 500 kilometers to reach optimal performance. In the first few days of driving, I usually deliberately slow down my pace, avoiding sudden braking or high-speed driving. During this period, the brake pads and rotors need to gradually conform to each other, forming an even friction surface to prevent noise and braking slippage. The break-in process is phased: gently press the pedal for the first 100 kilometers, then gradually increase the intensity to allow the temperature to rise steadily. After the break-in, the brake response becomes more sensitive, and the lifespan is extended. I also recommend checking the wear condition of the pads and rotors every 200 kilometers, combining it with vehicle maintenance to ensure safety. Remember, even if you're in a hurry to use the car, be patient to avoid unnecessary repair costs.
