Why does the p light keep flashing?

[BradleyLee]

The p light in a car is the brake system warning light, also known as the parking brake warning light. When the p light is on, it indicates a fault in the vehicle's braking system. The car should be pulled over immediately for inspection to avoid potential safety hazards. Below is an introduction to the parking brake: 1. Traditional mechanical parking brake: Uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. It features mature technology, low cost, and easy operation. However, since it uses cable control, prolonged use may cause cable loosening or deformation, requiring frequent maintenance. 2. Foot-operated parking brake: A parking brake controlled by a foot pedal. 3. Electronic parking brake: Typically equipped in mid-to-high-end vehicles.
