Hydraulic fluid is important for the functioning of the car’s hydraulic system, which controls the power steering, clutch, and brakes. Leaks can occur due to the age and wear of the hoses or seals, damage caused by foreign objects or accidents, or leaks in the hydraulic fluid tank or in the master cylinder. If there is a leak, there may be a loss of pressure and it may negatively affect the safety and performance of the car, so it is important to take it to a mechanic to revise and repair it if necessary.
