Does the BMW 3 Series require decoding when replacing brake pads?
1 Answers
If the sensor line is replaced, decoding is required; if not, simply reset the mileage. Any vehicle requires a break-in period after replacing brake pads. This is because new brake pads need to wear in to achieve optimal contact with the brake discs and deliver maximum braking performance. Therefore, braking force may temporarily decrease after replacement—just be cautious and drive around 1,000 kilometers for proper bedding-in. On-road bedding-in method: Drive the car at around 90 km/h, then lightly apply the brakes—just enough to feel the pads make contact with the discs—and maintain this gentle pressure. Mechanic-assisted sanding: When installing new brake pads, ask the mechanic to sand them. Some mechanics do this automatically to prevent brake noise, as reopening the assembly incurs no additional labor cost. Sanding only affects the edges and doesn't impact the lifespan, since the central portion of the pads provides the primary braking surface.
