Question: Buick vehiclesbrakeDoes the oil need to be changed regularly?

Answer: Everyone knows that in hydraulicsBraking SystemMedium, is relying on the incompressibility of the brake fluid, so that the driverBrake pedalThe mechanical force on the brake is transmitted to the brake pumps to generate braking force to achieve braking.When the vehicle is braking, especially during emergency braking, due to friction,Brake CylinderVery high heat will be generated, and the brake fluid in the pump body must be able to withstand this heat without being vaporized, otherwise it may cause the brake to fail! The brake fluid itself has strong water absorption. After long-term work, due to its own characteristics, it will always inhale some water vapor in the air, which reduces the boiling point of the brake fluid and makes the brake fluid easy to vaporize.

In order to reduce or eliminate the hidden dangers of braking safety caused by brake fluid, the brake fluid with the same mark must be replaced regularly according to the manufacturer's requirements. Buick vehicles require that the brake fluid be checked or replaced after two years or 50,000 kilometers. Two types of brake fluids, DOT3 and DOT4, are used on Buick vehicles. Because of their different compositions, mixing them is forbidden. Pay special attention when refilling them.

Question: How to take care of car battery in winter

Answer: The battery plays an important role in the use of the car. If it cannot supply power normally, the first reaction is that the engine cannot be started. At the same time, the power consumption of the car in winter is much greater than in other seasons, and the battery is most afraid of low temperatures. Battery in low temperature environmentcapacitanceThe amount is much lower than the capacitance at room temperature. The battery life is about two years, and it can be extended if you take care of it properly. The maintenance of the battery is actually not complicated, you can do it yourself.

The first step is to wipe the outside of the battery with a damp cloth, and put the panel and column head on
