How to service and repair the brake master cylinder on Mercury Mountaineer?

Service and repair of the brake master cylinder starts with disconnection of the brake fluid level warning switch and brake pressure switch if cruise control exists. The two brake lines must be unconnected after which the lines along with the brake master cylinder ports should receive plugs to stop fluid from leaking out. Cover the brake master cylinder section of vehicles using 4.0L engines by unfastening their wiring retainer clip. Next, remove brake master cylinder nuts to remove the unit for replacement. During installation please follow the removal procedure in reverse until the brake master cylinder bleeds properly before system installation and after which bleed your vehicle brake system for proper operation. Careful handling is vital for polyglycol ethers and polyglycols which appear in brake fluid since eye exposure needs immediate professional help. Take proper handwashing steps following fluid contact and look for emergency care for any skin irritation symptoms. Swallowing an ingestion requires water drinking followed by vomiting induction until reaching a healthcare facility quickly.
