What does the red exclamation mark in the car mean?
1 Answers
If the car displays an exclamation mark inside a circle with parentheses, it indicates a brake system malfunction. Here is relevant information about the brake system: 1. Function: To ensure safe driving of the car, improve the average driving speed, and enhance transportation productivity, dedicated braking mechanisms are installed on all types of vehicles. This series of specialized devices is collectively referred to as the brake system. 2. Principle: It mainly consists of wheel brakes, hydraulic transmission, and pneumatic transmission mechanisms. The wheel brake primarily comprises rotating parts, fixed parts, and adjustment mechanisms. The rotating part is the brake drum; the fixed parts include the brake shoe and brake backing plate; the adjustment mechanism consists of eccentric support pins and adjustment cams used to adjust the shoe-drum clearance.
