It can be concerning when you notice the oil light come on when you apply the brakes. You may wonder if there is something seriously wrong with your car or if it is just a minor issue. In this article, we will explore the reasons why your oil light may come on when you brake and what you can do about it.
Reasons Why Your Oil Light Comes On When You Brake
Low Oil Pressure
The most common reason why the oil light comes on when you brake is due to low oil pressure. When you apply the brakes, the oil pressure drops, and the sensor in the engine detects this drop in pressure, causing the warning light to illuminate. Low oil pressure can be caused by a number of factors, including:
- Low oil level
- Worn engine bearings
- Faulty oil pump
- Oil leaks
If you suspect that low oil pressure is the cause of your oil light coming on when you brake, you should check your oil level and have your car inspected by a qualified mechanic.
Brake Master Cylinder Issues
Another reason why your oil light may come on when you brake is due to issues with the brake master cylinder. The brake master cylinder is responsible for generating hydraulic pressure in the brake system, and if it is faulty, it can cause the oil light to come on. This is because the brake master cylinder shares a reservoir with the engine oil, and if there is a leak in the brake system, it can cause the oil level to drop, triggering the oil pressure warning light.
If you suspect that your brake master cylinder is causing the oil light to come on when you brake, you should have your brakes inspected by a qualified mechanic.
What You Can Do About It
If you notice that your oil light comes on when you brake, there are a few things that you can do to address the issue:
Check Your Oil Level
The first thing you should do is check your engine oil level. If it is low, you should add more oil to bring it up to the recommended level. If you notice that your oil level is consistently low, you may have an oil leak that needs to be repaired.
Have Your Car Inspected
If you have checked your oil level and it is not low, you should have your car inspected by a qualified mechanic. They can diagnose the issue and recommend the necessary repairs to fix the problem.
Replace Your Brake Master Cylinder
If your brake master cylinder is causing the oil light to come on when you brake, you will need to have it replaced. This is a job that should be performed by a qualified mechanic, as it involves removing and replacing the brake system.
Conclusion
If you notice that your oil light comes on when you brake, it is important to diagnose the issue and address it as soon as possible. Low oil pressure and issues with the brake master cylinder are the most common causes of this problem, but they can be easily resolved with the help of a qualified mechanic.
