• Q: How to Properly Prime and Bleed a Brake Master Cylinder Using DOT 3 Brake Fluid on 2007 Ford Ranger?

  A: Only DOT 3 brake fluid approved by authorities must be used for priming the brake master cylinder since alternative fluids result in permanent damage which makes the brakes non-functional. All painted or plastic surfaces must remain free from spills with immediate washing of affected spots using water. The braking operation needs clean brake fluid in the brake master cylinder reservoir while avoiding the use of any fluid which drained from the hydraulic system. Hydraulic system breaches from disconnection will require bleeding operations that can be completed through manual or pressure bleeding equipment methods. The process of in-vehicle priming requires disconnecting the brake tube fittings that attach to the brake master cylinder. To execute bench priming, route a soft cloth through a vise to defend the brake master cylinder while fitting bent short brake tubes into the reservoir before filling it with fresh brake fluid. Press the primary piston with caution or ask an assistant to pump the brake pedal until only clear brake fluid runs out of both tubes without forming air bubbles. Reinstall the brake master cylinder into the vehicle while filling up the reservoir with new fluid when required. The brake master cylinder needs to be bled by an assistant who holds the brake pedal while gradually unscrewing each outlet tube fitting one by one until no air bubbles appear during the bleeding process. The brake master cylinder outlet tubes need to be installed and fastened at 18 Nm (13 ft.lb) torque specification. You should loosen the brake inlet tube fitting at the 4WABS HCU while an assistant places their foot on the brake pedal. Then you should re-tighten this tube to a torque of 18 Nm (13 ft. lbs). You need to perform this bleeding procedure again on the second inlet tube until no more air bubbles appear after which you should bleed the full brake system.
