How Do You Bleed Air From Hydraulic Lines?

68

A hydraulic system passes hydraulic fluid through lines from the component that creates the pressure (the master cylinder) to the output components or pistons that transfer the pressure to perform the required task. Examples of the hydraulic system include motor vehicle hydraulic brakes, lifting arms of excavators and motor vehicle power steering systems. Air in the hydraulic system makes the system work inefficiently or to cease functioning. Procedures for bleeding hydraulic systems vary depending on the machinery. Consult the operation manual for your vehicle or equipment for specific instructions.
