  Q: How to service and repair the brake master cylinder on Lincoln Zephyr?

  A: The first step to work on the brake master cylinder requires disconnecting the battery ground cable. The procedure also involves disconnecting the brake fluid level warning switch electrical connector. A suitable suction tool should be used to empty brake fluid out of the brake master cylinder reservoir. When the vehicle includes a manual transmission users should disconnect the clutch master cylinder feed hose while plugging the opening. The brake tube fittings require disconnection along with proper plugging of brake tubes and brake master cylinder ports at 17 Nm (13 ft. lbs. torque) when finished with installation. The two brake master cylinder nuts need removal and subsequent tightening to 25 Nm (18 ft. lbs.) when reinstalling them. To complete the installation the brake master cylinder requires reverse installation steps alongside bleeding of the master cylinder and optional bleeding of the clutch master cylinder. Only DOT 3 brake fluid approved for motor vehicles should be employed because alternative fluids will cause permanent damage to brake components until the brakes become nonfunctional. Take all necessary precautions when working with brake fluid because its polyglycol ethers and polyglycols can be harmful substances that require proper safety measures such as eye protection and thorough hand washings after use. Seek medical assistance if irritation occurs. Boots containing brake fluid should immediately get rinsed with water because the fluid has a corrosive effect on surfaces of paint and plastic materials.
