What does the brake-pads-worn warning light indicate?

BrakePadsWorn indicates an issue with the brake pads, requiring inspection of the braking system. This warning light typically illuminates when the parking brake is engaged or during braking, and automatically turns off after braking is completed. If the brake warning light remains brightly lit, it signifies a malfunction in the braking system, necessitating immediate repair at a service center. Below are the benefits of lubricating brake calipers and cleaning brake discs. Brake Caliper Lubrication Maintenance: Lubricating the moving shafts and rubber cups of brake calipers maintains the flexibility of caliper bushings and extends their service life. It is essential to use fully synthetic brake caliper lubricant. Brake Disc Cleaning: Quickly removes oil stains, dirt, and friction dust from brake discs, drums, and any related components, ensuring optimal heat dissipation from the brake discs. This process also eliminates screeching brake noises and promotes even braking performance.

Last time I was driving my old Accord to pick up my kids from school, a yellow exclamation mark inside brackets suddenly appeared on the dashboard. I quickly checked the manual and found out it was the brake pad warning light. The mechanic told me this light means the brake pads have worn to their limit, and the metal backing plate grinding against the rotor would make squealing noises. The scariest part is that braking distance can increase by 3-4 meters in rainy weather. Once I almost rear-ended someone on the overpass. Now during every maintenance service, I make sure the mechanic measures the thickness - anything below 3mm gets replaced immediately. When it comes to safety, you really can't cut corners.

I remember my first car was a used Ford Focus. One day, a horseshoe-shaped warning light appeared on the dashboard, and my friend said it was the brake pad warning. I specifically went to the repair shop to see the old pads that were removed—the original 12mm friction material had worn down to the thickness of a coin. The technician said most modern car models now come with wear sensors; when the brake pads wear down enough to expose the metal wire, contact with the brake disc completes the circuit and triggers the warning. I strongly advise against using aftermarket brake pads. Once, I installed a set of low-quality pads and immediately smelled burning as soon as I drove down the garage ramp.

The most common misjudgment in 15 years of running a repair shop: Some people confuse the brake system warning light (circle with exclamation mark) with the brake pad warning light (left bracket with squiggly line). When the genuine brake pad warning light is on, lightly pressing the brake will produce a high-frequency metal scraping sound—that's the wear indicator metal strip issuing a warning. For city driving, inspection is mandatory every 40,000 km; frequent mountain road driving requires even earlier replacement. Last week, a car owner ignored the warning light, resulting in deep grooves worn into the brake discs, multiplying the repair cost by five times.

My girlfriend used the brake pad warning light on her Fit as a decoration. Two weeks later, when I drove her car, I found that the brakes only slowed the car when fully depressed. I took her to a 24-hour repair shop overnight, and upon disassembly, we discovered that the left front pad was completely worn through, with the metal backing plate scratching the brake disc. The technician explained that modern vehicles have a two-stage electronic warning system: the initial stage is a dashboard warning light, followed by a beeping sound in the later stage. Here’s a self-check tip—roll down the window and drive slowly while lightly applying the brakes. If you hear a squeaking sound, get it inspected immediately; don’t wait for the system to alert you.

Last month while helping a fellow car enthusiast modify brake calipers, we discussed this topic. Modern cars have two types of brake pad warning systems: indirect and direct. The indirect type relies on computer calculations of braking force degradation to determine wear, while the direct type uses sensor wires embedded in the brake pads. German cars commonly use the direct system, which provides precise warnings but requires replacing the sensor wires along with the pads, adding about a hundred yuan to material costs. For car modifiers, we recommend choosing ceramic brake pads, which offer high hardness and produce less dust, thereby extending the life of the brake discs. Regularly checking the amount of tire dust is also a good method to assess wear.
