What Causes the Brake Warning Light to Illuminate?
2 Answers
Brake warning light illumination can be attributed to the following issues: Red Handbrake Issue: The red light indicates a critical warning prohibiting vehicle operation, typically caused by insufficient brake fluid or an improperly released handbrake. Yellow ABS System Fault: The yellow light represents a secondary warning allowing continued driving but requiring immediate inspection, such as worn brake pads or ABS system malfunction. Green Brake Lock: The green light serves as an indicator. Automatic transmissions feature a brake lock mechanism to prevent accidental gear shifting - the gear remains locked when the brake isn't depressed (accompanied by green light illumination), and releases when depressed (light extinguishes). This light shouldn't activate during normal driving.
Last time I was driving, the brake warning light came on and my heart skipped a beat. It might be low brake fluid, so I need to pop the hood and check the reservoir level. If it's low, just top it up with brake fluid, but make sure not to use the wrong type. It could also be that the brake pads are worn too thin and the sensor is triggering the warning—that's not easy to replace yourself, so it's best to go to a repair shop. An ABS system fault can also light up the warning, like if a sensor is dirty or loose. My experience as a seasoned driver is not to push through—pull over and check the pedal. If it feels soft or spongy, get it fixed right away—safety first. Regular brake checks are essential; a maintenance check every six months can prevent issues and avoid sudden problems on the road that could disrupt family trips.
