How to Decelerate an Automatic Transmission Car?

Automatic transmission cars decelerate by: 1. Applying the brake pedal, which pushes hydraulic pressure to make the brake calipers press against the brake pads. The brake pads then clamp onto the brake rotor, creating significant friction to generate braking force and slow down the vehicle; 2. Releasing the accelerator pedal to reduce fuel supply to the engine, which naturally causes the car to decelerate. The vehicle will automatically select the appropriate gear based on driving speed and traffic conditions. When starting an automatic transmission car, pay attention to accelerator pedal operation. Avoid pressing the accelerator heavily while still holding the brake pedal or before releasing the handbrake. Also, do not press the accelerator before shifting into P or N gear. First move the gear selector to the intended driving position, then press the accelerator pedal.

What is the difference between good and bad brake fluid?

Brake fluid quality can be distinguished by its grade. According to the international DOT classification standard, theoretically, the worst should be DOT3, followed by DOT4, and the better one should be DOT5. However, in reality, considering practical conditions, the best is DOT5.1 brake fluid, followed by DOT4 brake fluid, and finally DOT3 brake fluid. The three most important indicators for identifying the authenticity and quality of brake fluid are boiling point, low-temperature fluidity, and corrosiveness. Based on these indicators, the quality of brake fluid can be distinguished as follows: 1. Poor-quality brake fluid has poor high-temperature resistance: Under high-temperature conditions, it is prone to vaporization, forming bubbles that are easily visible to the naked eye, creating air resistance in the brake system pipelines and hindering the flow of brake fluid; 2. Corrosiveness test: Brake fluid mixed with methanol or mixed alcohols and water has strong corrosiveness to metal objects. Placing a metal object in it to observe whether it rusts can help identify its quality; 3. Fluidity test: Based on the kinematic viscosity characteristic of brake fluid, which is its fluidity at low temperatures. In extremely cold northern regions, qualified brake fluid can still flow normally, while poor-quality brake fluid will show varying degrees of solidification. Brake fluid in this state basically loses its braking performance, and once the brake fluid freezes and expands, it can burst the brake lines, leading to more severe consequences.
