Can changing brake oil reduce fuel consumption?

No, but replacement is good for the car. Replacing brake oil can ensure the braking performance of the car, maintain the car and prolong the service life of the brake system. When changing brake oil regularly, it is best to use original brake oil. : 1. Reason for changing brake oil: If the brake oil is used for a long time, it will wear the cup and piston in the brake pump, resulting in turbid brake oil, so it is better to change it. Brake oil is very important. Pay attention when choosing brake oil. If it is unqualified or of average quality, it will corrode the plug of the brake oil pump and affect the braking effect. So if the brake oil is low, you'd better go to specialty store to buy the brake oil of the original car, and don't spend a lot of money to save money. 2. Function of brake oil: Brake oil is also called automobile brake fluid. When the driver steps on the brake, the force on the pedal is transmitted from the piston of the master brake cylinder to the wheel cylinder through the brake oil, so that the friction plate opens to prevent the vehicle from moving forward. When the brake stops, the return spring pulls the friction plate back to its original position, and the brake oil plays the role of force transmission in the whole process.
