  Q: How to Properly Bleed the Brake Master Cylinder on Ford Flex?

  A:

  The bleeding procedure requires brake fluid that fulfills manufacturer requirements together with proper specifications, but the fluid should be new and separate from previous drained amounts because old fluid can cause damage and contamination. The brake master cylinder needs to stay filled with fluid throughout the process to protect both the system and the brakes from damage. Brake fluid should receive immediate water cleaning whenever it falls on painted surfaces or plastics. Before use or after draining the system, it is necessary to prime the new brake master cylinder to stop air from entering it. Begin the procedure by uninstalling brake tubes from the brake master cylinder port while simultaneously adding short tubes which will be submerged in clean brake fluid inside the brake master cylinder reservoir. An assistant should activate the brake pedal until it produces clear fluid through the tubes that remains bubble-free. The assistant should pump the brake pedal to empty the brake master cylinder brake tubes while maintaining pressure until their installation when each tube is bled. The mechanic releases the brake tube fittings at the rear position until fluid starts draining before tightening them under pedal pressure. Complete the process again by checking for clear bubble-free fluid but always maintain sufficient reservoir fluid to continue with front brake tube bleeding. The final steps involve securing all fittings to their specified torque specifications; after which proceed with pressure bleeding or manual bleeding to finish the system bleeding.
