What does the red square exclamation mark on the Ford dashboard mean?

[LeCayden]

The red exclamation light indicates a brake system malfunction. There are three types of brake systems: 1. Foot brake: The commonly used brake while driving is operated by the foot, hence also called the foot brake. When the driver presses the brake pedal, the braking force is transmitted mechanically or hydraulically to the wheel's braking device to generate friction. 2. Parking brake: Also known as the hand brake, it is a braking device to prevent the vehicle from sliding when parked. There are generally two types: the intermediate braking type installed on the drive shaft and the direct control rear wheel braking type. 3. Anti-lock braking system (ABS): When driving on slippery or icy low-friction roads, excessive braking can occur, causing the wheels to lock up and lose traction, leading to loss of directional control. To enable the vehicle to effectively control the direction of travel on such hazardous roads, the ABS "Anti-lock Braking System" was developed.
