  Q: How Do You Remove and Install a Master Cylinder on Dodge Ram 3500 and Ram 3500?

  A: To remove the Brake Master Cylinder, begin by locating it in the engine compartment, mounted to the power Brake Booster. Remove excess fluid from the reservoir using a syringe or turkey baster. Place rags under the fluid fittings and prepare caps or plastic bags to cover the line ends once disconnected. Loosen the brake line fittings at the Brake Master Cylinder using a flare-nut wrench to prevent damage. Disconnect the electrical connector at the brake fluid level switch, then remove the nuts attaching the Brake Master Cylinder to the power booster. Carefully pull the Brake Master Cylinder off the studs, being cautious not to spill fluid. If installing a new Brake Master Cylinder, transfer the reservoir and install new seals. For installation, bench bleed the new Brake Master Cylinder by clamping it in a vise and attaching bleeder tubes to the outlet ports. Fill the reservoir with the recommended brake fluid type and push the pistons into the Brake Master Cylinder to expel air into the reservoir. Repeat until no air bubbles are present. Remove the bleed tubes, install plugs in the ports, and attach the reservoir cap. Install the Brake Master Cylinder over the power brake booster studs, tighten the attaching nuts finger-tight, and thread the brake line fittings into the Brake Master Cylinder. Fully tighten the nuts. Connect the brake fluid switch electrical connector, fill the reservoir with fluid, and bleed the Brake Master Cylinder and brake system. Test the brake system's operation carefully before normal vehicle use.
