Why are the tail lights of Ford Focus on?

[IsabelleMarie]

Here are the reasons why the tail lights of Ford Focus are on: 1. Lack of brake fluid: Brake fluid is an indispensable part of the car's braking system. When the driver steps on the brake pedal, the force applied to the pedal is transmitted by the piston of the master brake cylinder through the brake fluid to the brake cylinders located at each wheel, causing the brake pads to contact the wheels and stop the vehicle. 2. Poor contact: It is necessary to check whether the brake switch has poor contact or is loose and not reset, whether there is poor contact or a short circuit in the brake circuit, whether the brake pedal rubber pad is punctured, whether the brake rubber ring is severely worn, or whether the brake switch is damaged. 3. Severe wear of brake pads: The light will also stay on, and the brake pads need to be replaced.
