Q: How to Properly Service and Install a Brake Caliper for Front on Mercury Mariner?
A: The brake caliper service and repair process starts with parking the vehicle in NEUTRAL position on a hoist. The brake caliper requires its clip removal before you loosen the brake caliper jounce hose at the caliper then you should retighten it to 20 Nm (15 ft. lbs.) when reinstalling. The first step involves unwrapping the two brake caliper dust boot caps followed by removing the two brake caliper guide bolts which must be tightened to 35 Nm when using the disc-drum brake system and 45 Nm when using the four-wheel disc brake system during reassembly. Extract the brake caliper by stem-unthreading it from the brake caliper jounce hose while maintaining an untwisted hose position. The installation process ends through reverse implementation and system brake bleed procedure. Brake components will sustain permanent damage which leads to brake failure when using fluid other than the specific DOT 3 motor vehicle brake fluid that DOT has approved for use. Handle brake fluid with proper caution when performing tasks because contact with eyes or painted or plastic surfaces can be dangerous - any spills must be washed right away using water.
Q: How to properly bleed a brake caliper on Mercury Grand Marquis?
A: The brake caliper should receive clean brake fluid which satisfies manufacturer's standards while excluding drained fluid for contamination prevention. The brake master cylinder reservoir must receive continuous clean specified brake fluid during the process since letting the reservoir empty will harm brake system elements. Bathed brake fluid needs immediate cleanup because it can damage painted and plastic vehicle surfaces. Vehicle operators should disable the fire suppression system before starting any operation because ignoring this step can lead to fatal injuries. A complete brake system bleed is not needed when disconnecting the disc brake caliper alone. The procedure begins with removing the brake caliper bleeder screw cap while installing a box-end wrench onto the bleeder screw before attaching a rubber drain hose which should be submerged into clean brake fluid. An assistant should maintain constant force on the brake pedal while you follow with screw bleeder loosening to produce brake fluid output through the hose. The bleeding process ends when only clear fluid without bubbles appears then proceed to tighten the bleeder screw followed by mastering the brake reservoir level when necessary. After specifying the required torque you should tighten the brake caliper bleeder screw before removing both the rubber hose and bleeder screw cap. A fire suppression system operating on the vehicle needs to have its recharging process completed before finishing brake bleeding operations.
Q: How to service and repair a brake caliper on Mercury Cougar?
A: A block of wood or shop rags should go between the caliper piston and the caliper housing before its removal for brake caliper service. Compressed air extraction will remove the caliper piston from the housing before you discard the dust seal and piston seal. Inspection of both the caliper piston and piston bore must happen before replacement of the piston when pitting or scoring appears. Lubricate the piston bore and caliper piston together with High Performance Dot 3 Brake Fluid C6AZ-19542-AB or a Dot 3 equivalent following Ford specifications ESA-M6C25-A. Afterwards, install a new piston seal in the grooved piston bore and secure a new dust seal onto the caliper piston. Put the caliper piston into the caliper bore while avoiding damage to both components then insert the dust seal before installing the caliper assembly.
