The Cruze's brake suddenly becoming hard and difficult to press is due to a failure in the vacuum booster pump, which needs to be replaced immediately. Below is a partial introduction about the automotive braking system: 1. The braking system of a car is crucial as it affects the vehicle's driving stability and safety. 2. The main components of the braking system include the vacuum booster pump, master cylinder, wheel cylinder, brake pads, and brake discs. 3. The vacuum booster pump provides assistance; after the driver presses the brake pedal, the vacuum booster pump can offer assistance, making it easier for the driver to press the brake pedal. 4. After pressing the brake pedal, the master cylinder pushes the wheel cylinder through brake fluid, and the wheel cylinder can then push the brake pads to clamp the brake discs, thereby slowing down the vehicle.

How long does it take to fully charge the battery when the car is running?

It takes 20 hours to fully charge the battery when the car is running. The charging method for a 12V60Ah battery is constant voltage and current limiting. Charge at a constant voltage of 14.8V and a current limit of 15A for 16 hours, followed by a constant current of 3A for 4 hours, totaling 20 hours of charging time. The optimal charging time for a car battery is between 18 to 24 hours. In low-temperature environments, the battery capacity is much lower than at normal temperatures, so car owners should regularly inspect and maintain the battery. Avoid leaving the car parked in open parking lots for extended periods. If the car is to be parked long-term, the battery should be removed and taken away to prevent freezing damage. After turning off the car, all high-power electrical devices should be turned off to avoid damage to the car battery.
