What to Do When the Brake Disc Warning Light Comes On?
2 Answers
The brake disc warning light coming on suggests that the fault cause should be checked promptly. It may be due to severely worn brake pads or insufficient brake fluid level. Here is some related information about brake discs: 1. Material: Brake discs are made of China's gray cast iron 250 standard, abbreviated as HT250, equivalent to the American G3000 standard. The requirements for the three main chemical elements are: C: 3.1~3.4, Si: 1.9~2.3, Mn: 0.6~0.9. 2. Function: Brake discs are used for braking, with the braking force coming from the brake caliper. When the brake is applied, the caliper clamps the brake disc to slow down or stop the vehicle. Brake discs offer effective braking performance and are easier to maintain compared to drum brakes.
Recently, my friend's car also had the brake disc warning light come on, which is usually due to excessively worn brake pads or insufficient brake fluid. Don’t rush to drive; park the car in a safe place and check it first. If you know how, take a look at the thickness of the brake pads—if they're too thin, they need to be replaced. If the brake fluid is low, just top it up with the same type of fluid. However, if the ABS light also comes on the dashboard at the same time, it might be a sensor failure. This situation is not something to take lightly—brake system issues are extremely dangerous, so it’s best to contact a repair shop immediately. Also, pay attention to cleaning the wheel hubs when washing the car, as excessive brake dust can trigger false warning lights.
