Will the brake disc not stop at all if there is engine oil on it?

[LeAnna]

If there is engine oil on the brake disc, it will not stop at all. Here are the relevant explanations: 1. Reduced friction: Modern cars are equipped with ABS. If there is oil on the brake disc, it will cause the brakes to fail to stop, reducing friction and leading to deviation or skidding. When changing the engine oil, if the oil spills onto the belt, the belt will slip. Only by cleaning it off can the slipping be avoided. 2. Brake fluid: It is inherently hydrophilic. After prolonged use, the water content in the brake fluid will increase, causing the boiling point of the brake fluid to decrease. This makes the brake fluid more likely to reach the boiling point, generating bubbles and resulting in brake failure. Moreover, brake fluid that has been used for a long time contains more impurities, which can degrade braking performance or even damage the brake system. Generally, there are warning signs when the brake fluid needs to be replaced. If you notice that the braking force varies between light and heavy, it may be time to replace the brake fluid.
