Why does the oil light come on when braking?
2 Answers
When the oil light comes on while braking, it is due to insufficient oil or the use of low-quality oil. Here is relevant knowledge about the oil light: 1. Concept of the oil light: The oil light is a component that monitors the normal oil pressure. 2. Hazards of oil light warning: Only normal oil pressure can ensure that oil is delivered to all friction surfaces of the engine. Too high or too low pressure will affect the normal operation of the engine and may even cause damage to engine components. Therefore, when the oil light comes on, the engine should be stopped immediately to identify the cause, and operation should only resume after the fault is resolved.
I've been driving for so many years and have encountered the oil light coming on during braking a few times. Usually, this is related to the car decelerating during braking, causing the oil in the oil pan to surge forward. If your oil level is already low, the oil pump can't pick up enough oil, the pressure drops suddenly, and the light comes on. This issue can range from minor to serious—possible causes include the oil level being too low, the oil pump aging or wearing out, or a faulty sensor. I remember last year when I was on a long drive, the light came on during a sudden brake, and I was so scared I pulled over immediately. Checking the dipstick, I found the oil was more than half gone, and adding some oil fixed it. But if not addressed in time, poor engine lubrication can lead to metal-on-metal contact, and repairs can be costly. So my advice is, if you see the light come on, safely pull over and check the oil level right away. If it's low, top it up; if the problem persists, it's safer to consult a professional. Make it a habit to glance at the dashboard when stopping at traffic lights—it helps prevent issues before they arise.
