  Q: How to service and repair the brake master cylinder on Mercury Villager?

  A: The first step in maintaining the brake master cylinder involves removing both the brake master cylinder and plastic hose fittings and then the plastic retainer. First detach the valve stopper bolt through primary piston pushing and after that extract the rubber bushings from the brake master cylinder. Beginning with the primary piston requires pushing down to remove the snap ring and afterward extracting the primary piston from its place. Afterward, remove the secondary piston. Start the assembly by following the reverse order of disassembly while applying High Performance DOT 3 Motor Vehicle Brake Fluid C6AZ-19542-AB or an equivalent fluid that satisfies Ford specification ESA-M6C25-A, DOT 3 to the brake master cylinder bore along with new piston seals and pistons.
