Here's why:
* Engine oil is incompatible with brake system components: Brake fluid is specifically designed to resist heat, maintain viscosity, and absorb moisture. Engine oil lacks these properties, making it a disastrous substitute.
* Engine oil contaminates the brake system: This contamination can lead to:
* Reduced braking effectiveness: The oil reduces the friction between brake pads and rotors, leading to a mushy brake pedal and extended stopping distances.
* System failure: The oil can damage brake lines, calipers, and other components.
* Corrosion: Engine oil can attract moisture and corrode metal parts within the braking system.
What you should do:
1. Do not drive the vehicle! The brakes are compromised and driving is extremely dangerous.
2. Contact a qualified mechanic immediately. Explain the situation clearly.
3. Have the brake system flushed and thoroughly inspected: The mechanic will need to remove all contaminated fluid and replace it with the correct brake fluid. They will also inspect the brake lines, calipers, and other components for any damage.
4. Get the system bled: Air bubbles can enter the system during the flushing process, so bleeding is crucial to ensure proper brake performance.
Remember: Even if you only added a small amount of engine oil, it's vital to have the brake system professionally inspected and repaired. Your safety depends on it!
