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

  A: Service and repair procedures for the wheel cylinder should start by removing the dust boots from their wheel cylinder housing grooves before extracting each boot and piston. The wheel cylinder piston cup spring from the rear bore and cups need to be removed before the back housing bleeder screw gets taken out. The rubber parts should be discarded and all washable components need cleaning with denatured alcohol. The inspection process should identify any scratches or scoring or visible damages on pistons which require replacement. Clean the wheel cylinder housing with freshly prepared alcohol solution. Inspection of the rear wheel cylinder bore should be done for signs of damage or surface imperfections which might need honing unless the diameter exceeds 0.08 mm (0.003 inch) beyond factory specifications. Verify the safety of the wheel cylinder bleeder screw hole and perform cleaning when needed. Reverse the disassembly procedure to assemble the system with High Performance DOT 3 Motor Vehicle Brake Fluid C6AZ-19542-AB or a DOT 3 equivalent that matches Ford specification ESA-M6C25-A on all internal parts.
