Since BMW began to equip the M xDrive four-wheel-drive system, the acceleration performance of M Car has been greatly improved. The M8 Thunder version actually measured a 2.80-second acceleration of 100 kilometers, which is indeed comparable to the supercar! It is necessary to brake quickly, and braking performance is also very important for a car. Seeing this, did you think of the carbon-ceramic brake system of BMW that is known as the "golden legend"? It can effectively reduce the weight of the car, improve the dynamic performance and acceleration performance of the vehicle, but this configuration needs to be optional.
In general, what are the factors that affect BMW's braking performance?
1. Tire
The tire is a component that directly contacts the vehicle and the road, and also directly affects the life safety of passengers in the vehicle. In order to ensure safety, it is recommended that the tire tread depth in summer is less than 3mm, and the tire tread depth in winter is less than 4mm, and it should be replaced according to the aging and wear of the tire.
2. Brake caliper
Brake calipers are also an important part of the brake system. BMW calipers have single-piston, dual-piston, four-piston, six-piston, and other categories. The more pistons, the greater the braking force, and the greater the impact on the braking distance. BMW Golden Carbon Ceramic brake calipers are six-piston.
3. Brake fluid
Brake fluid, also known as brake fluid, is a liquid medium that transfers brake pressure in a hydraulic brake system and is the nerve center of the entire brake system. Brake fluid is hygroscopic. As the mileage increases, it will absorb moisture from the surrounding air. In order to ensure the normal operation of the vehicle's brake system, regular inspection of the brake fluid can effectively increase the braking distance. BMW officials recommend that it be replaced once every 3 years. Dynamic fluid.
4. Brake disc
The brake disc is one of the most direct factors that affect the braking effect. Prolonged use will increase the wear of the brake disc. If the brake has abnormal vibration or the brake does not stop, it must be checked and replaced in time. The official recommendation is to replace the brake disc every 60,000 to 100,000 kilometers. If the wear is found to exceed 2.4mm (M model 1.6mm), it must be replaced to maintain the best braking force.
5. Brake pads
The brake pads cooperate with the brake disc to provide the braking force for the vehicle. It is one of the most important and one of the safety components that bear higher pressure. The importance of the brake pads is self-evident. Braking accuracy and braking efficiency are decisive factors for brake safety. Regular inspection and replacement of brake pads are essential. Officials recommend replacing brake pads every 50,000 to 50,000 kilometers. Actual conditions also need to be based on specific vehicle conditions However, when the thickness of the brake pad is less than 3.7mm, it must be replaced.
These five are life-threatening components, and they are not sloppy at all. They must be able to withstand the test of extreme environments. For example, the original brake discs/brakes equipped by BMW are specially designed and tuned. Equipped with the interaction of various factors such as the body, chassis, engine, aerodynamic characteristics, anti-lock brake system of different models.
