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

  A:

  Processing or repairing the brake master cylinder necessitates disconnecting the battery ground cable first. The first step requires you to take off the air cleaner outlet pipe followed by disconnecting the brake fluid level sensor electrical connector. End the brake tubes by disconnecting fittings then take out the bolts which attach the brake master cylinder to the vehicle. The installation of a new master cylinder requires prefect bench bleeding of the unit before insertion into the system. The brake system needs bleeding after complete reversal of removal procedures. Brake system functioning becomes impossible when unapproved DOT 3 brake fluid is used because it produces long-lasting harm to brake parts. Maintain safe handling of brake fluid because it contains chemical compounds known as polyglycol ethers and polyglycols that could cause harm; thus avoid direct contact with eyes and cleanse your hands thoroughly when you finish working with it. Wash affected eyes with running water for fifteen minutes after which you should consult medical professionals in case eye irritation continues. Consuming brake fluid requires victims to intake water followed by vomiting so they can immediately receive medical help. Caution must be exercised when dealing with brake fluid due to its ability to harm painted surfaces and plastic materials so washing the contaminated area right away with water becomes necessary.

  Q: How to Prime the Brake Master Cylinder with DOT 3 Brake Fluid on Mercury Sable?

  A:

  Brake fluid from the DOT 3 category should be used exclusively to prime the brake master cylinder since it protects brake components and allows proper brake operation. Use extreme caution when handling brake fluid because its polyglycol ethers and polyglycols can induce skin irritation while flushing eyes that come in contact with it requires 15-minute water irrigation before seeking medical help in case of continuing discomfort. Wash all painted and plastic surfaces contaminated by brake fluid using water to prevent damage. The bleeding task requires you to keep the brake master cylinder reservoir at the specified fluid level while forbidding the reuse of drained brake liquid. Any disconnected parts of the hydraulic system need bleeding because air can enter through such openings when reconnection takes place. To prime brakes inside the car you must detach the brake tubes from the brake master cylinder. Place the brake master cylinder inside a vise and mount short brake tubes into its reservoir while filling it with DOT 3 brake fluid. The primary piston should be gently pressed by yourself or through an assistant pump of the brake pedal while making sure both tubes give clear fluid flow without air bubbles forming. The brake master cylinder can then be added to the vehicle along with new outlet tube attachment. Recharge the reservoir when needed while an assistant maintains pressure on the brake pedal before proceeding to loosen each outlet tube then retighten them. The procedure gets repeated without air bubbles present during fluid expulsion before moving onto brake system bleeding.
