Why is the Honda brake light always on?
2 Answers
Honda brake light stays on due to worn brake pads or insufficient brake fluid. Below are detailed explanations for the reasons why the Honda brake light remains illuminated: 1. Worn or aged brake pads: If the thickness of the brake pads is below the specified value, typically 0.8 cm, there is a high risk of them cracking during driving, which can be dangerous. 2. Insufficient brake fluid: Brake fluid plays a crucial role in the vehicle's braking system. When the brake pedal is pressed while driving, the force applied to the pedal is transmitted through the master cylinder piston via the brake fluid to the individual wheel brake cylinders, causing the brake pads to contact the wheels and stop the vehicle. Insufficient brake fluid can cause the brake pedal to sink, keeping the brake switch continuously powered, which results in the brake light staying on.
I often help friends check their cars. It's quite common for Honda brake lights to stay on, mostly because the brake switch gets stuck. That switch is behind the brake pedal, and after long use, dust buildup or a loose spring can keep triggering the light. If you're checking it yourself, gently press the pedal and listen for a click—no sound means the switch is the issue. Just a heads-up: a constantly lit brake light not only drains the battery but also confuses drivers behind you into thinking you're braking, increasing the risk of a rear-end collision at night. Get it fixed ASAP—a new switch costs just a few dozen bucks, saving you the hassle of towing it to the shop. Wiping that area during regular maintenance can prevent this. Hondas are prone to switch issues over time, so don't ignore it.
