What Causes the High-Mount Brake Light on a Volkswagen Santana to Stay On Constantly?
1 Answers
Volkswagen Santana's brake light staying on constantly is caused by the brake linkage failing to disconnect the contact plate inside the trigger component after returning to its position. Reasons for the high-mount brake light staying on constantly: Lack of brake fluid, which is an essential part of the vehicle's braking system. When the driver presses the brake pedal, the force applied is transmitted by the master cylinder piston through the brake fluid to the wheel brake cylinders, causing the brake pads to contact the wheels and stop the vehicle. Add brake fluid, check if the brake switch has poor contact or failed to reset after loosening, and inspect the brake wiring for poor contact or short circuits. Solutions for the high-mount brake light staying on constantly: At the high-mount brake light, disconnect the connector plug and use a test light to check if there is a signal output to the connector plug when the brake pedal is pressed. If there is a signal, the issue lies with the brake light assembly. If there is no signal output, also observe whether the brake bulbs at the taillights can illuminate normally.
