Brakes are one of the most vital systems in any vehicle that we rely on again and again. When your foot applies pressure on the brake pedal, the brake pads make contact with the brake disc as it makes the vehicle come to a complete stop. The goal is to optimize the balance of deceleration behavior, wear and comfort, while maximizing safe operation of the vehicle.
There are various causes that can trigger brake noise in any BMW vehicle such as; driving style, environmental condition (hot/cold weather climates), and prior wear to the brake pads. Extreme temperature (IE summer in Phoenix, AZ or winter in New York) can change the material properties of the brake pads and any lubricant materials, causing noise that will usually go away when temperatures return to normal. The noise is produced by a vibration of brake components. The vibration can build up a resonance which becomes an audible brake squeal. Noise and vibration may occur with increasing wear.
Grooves on the brake disc can occur over a period of time due to material deposits, road debris, contamination and corrosion. The grooves will not affect the brakes functionality. Having your vehicle checked by a BMW certified technician will help to determine if action is required due to groove depth. Average aging and mileage related wear to brakes and discs results in material and dimension changes.
Another key factor in brake noise can come from suspension components and wheel bearings can cause noise when braking and should be check by a certified BMW technician. Corrosion and discoloration on brake discs may happen in moderation during the life of the discs. Slight to moderate corrosion is normal and will not affect the reliability of the brake system. Light surface corrosion on the brake discs may occur with normal brake usage. Extremely strong corrosion can take significantly longer to be cleaned off, usually leads to significant noise when braking and should be replaced.
For new vehicles the break in period for brake pads to get optimal performance is usually within 125-150 miles, but this all depends on the individual driving style. Applying the brakes gently is a key process within the first 150 miles of use.
