What happens if you mix brake fluid with oil?
The oils can cause rubber to swell or deform, and because there are lots of rubber seals in your brake system, that eventually can make your brakes stick, leak or even fail.
Why did I put wrong oil in my brake fluid?
Perhaps someone poured in motor oil, or power steering fluid into the brake reservoir when they “topped off” the fluids. If the fluid in the system didn’t deteriorate due to age, then someone added the wrong fluid. The timing of the oil change coincides neatly with brakes failing 3 days later.
What happens if you top off a master cylinder with brake fluid?
Brake Fluid Contamination. Cause: Untrained person topped off master cylinder with fluid other than brake fluid. Brake rubber parts are not compatible with petroleum based fluids. Exposure to these fluids will cause the rubber parts to swell as shown in Figure 69.1.
What happens when the brake fluid is contaminated?
Note: Some customers will request a partial repair when their system becomes contaminated. This should almost never be done. Brake fluid circulates through the system. Every stroke of the brake pedal takes brake fluid from the reservoir and brings it into the hydraulic system.
What kind of fluid should I use for my brake system?
So please pay attention to what you add to the brake system. It will only take a small amount of any other like trans fluid, power steering fluid, coolant, and oil to set you on your way of having a large repair bill. Use ONLY approved brake fluid to top off or flush your brake system!

What can I use to top off my brake system?

Use ONLY approved brake fluid to top off or flush your brake system! Below are two pictures where you can see how contamination expands the rubber of the brake fluid reservoir cap.
What happens if you mix brake fluid with water?
Of brake fluid from the top of the reservoir and mixed it into some water. The brake fluid mixed well with the water and there were no signs of oil/oil-based substance. I would imagine the oil would have floated to the top if present.
