What Causes the Brake Light to Come On?
The brake light can come on due to a variety of reasons, ranging from minor issues to serious problems. Here are some common causes:
- Braided brake hose: Over time, the braided brake hose can become damaged or worn out, causing the brake light to come on.
- Low brake fluid level: If the brake fluid level is low, it can trigger the brake light to come on.
- Brake pad wear: Worn-out brake pads can cause the brake light to come on, as the sensors detect the reduced brake pad thickness.
- Brake caliper issues: Problems with the brake caliper, such as corrosion or misalignment, can also trigger the brake light.
- ABS sensor issues: The Anti-lock Braking System (ABS) sensors can malfunction, causing the brake light to come on.
- Faulty brake switch: A faulty brake switch can prevent the brake light from turning off, even when the brakes are not engaged.
What Are the Symptoms of a Faulty Brake Light?
When the brake light comes on, you may notice some common symptoms, including:
- Brake light illumination: The brake light will be illuminated on the dashboard, usually in the shape of a circle or a rectangle.
- Reduced brake performance: If the brake pads are worn out or the brake fluid level is low, you may notice reduced brake performance, such as spongy brakes or a longer stopping distance.
- Grinding or screeching noise: Worn-out brake pads can cause grinding or screeching noises when you press the brake pedal.
- Vibrations or pulsations: If the brake caliper is misaligned or the brake pads are worn out, you may feel vibrations or pulsations when you press the brake pedal.
