How to Properly Service and Repair a Brake Caliper for Front on Mercury Mariner?

Before proceeding with brake caliper services begin by taking out the disc brake caliper and fix it in a vise for safekeeping. Discard the bleeder screw cap before taking out the bleeder screw then re-tighten it to 16 Nm after installation. Short bursts of air pressure at moderate strength should be used to avoid piston uncontrolled movement when conducting a brake caliper inspection. Check for brake caliper piston and bore deterioration due to wear or corrosion or pitting; any evidence of damage requires new caliper installation. The caliper piston can be removed while inserting a wooden block between piston and housing to direct compressed air from the jounce hose port. You should remove the dust boot from the caliper bore before using a plastic or wooden pick to safely extract the piston seal without damaging the seal groove. The reassembly process starts with following different disassembly steps while applying clean brake fluid for lubricating the piston seal. Any attempt to use brake fluid other than DOT 3 designated for automobiles will result in lasting damage to brake equipment and render the brakes completely non-functional. Practicing cautious handling of brake fluid remains vital because it has the potential to damage painted surfaces and plastic elements on your vehicle. Therefore keep all spills away from your paintwork to avoid rinsing with water right away.

How to properly bleed a brake caliper on Mercury Mariner?

The brake bleeding process requires using fresh brake fluid approved by the manufacturer which needs to be processed independently of drained fluid to maintain system cleanliness and system components. The proper braking function demands that the brake master cylinder stay filled throughout the bleeding process. Brake fluid spills should never touch painted or plastic surfaces yet immediate water cleaning is necessary to remove any fluid dripping onto such materials. The brake system needs no full bleed when the brake caliper was either disconnected or had new installation. The bleeder screw cap needs removal as you install a box-end wrench on the bleeder screw. The bleeder screw requires a rubber drain hose attachment to a fluid reservoir which contains clean specified brake fluid. Your assistant should pull the brake pedal twice before maintaining constant force on it. After the bleeder screw releases brake fluid there must be a pedal pressure held by the assistant before you tighten the screw again. The user should continue the braked vessel evacuations until they achieve fluid clarity with no bubble formation before restocking the brake master cylinder container with fluid. You must first retract the bleeder screw enough to produce a brake fluid stream before retightening it to specification and removing the rubber hose together with replacing the bleeder screw cap. The braking system needs multiple tests to verify its correct operation.

The Brake Caliper in Mercury vehicles used in Mariner cars is very essential i the braking system because it converts hydraulic pressure from the master cylinder into mechanical force. This force is used to apply pressure on the brake pads against the rotors in order to enable the car slow down or stop. Mercury Mariners utilize two primary types of Brake Calipers: There types are fixed and floating. Fixed have pistons in two sides of rotor and apply equal pressure; floating have pistons only on one side of the rotor and moves to apply pressure and they provoke uneven wear if not checked frequently. Brake Calipers used through the years for the Mariner series have varied in terms of building material and performance parameters. OEM calipers are adequate for normal road use, performance calipers are better in braking and looks and are designed for uses on tracks or race tracks. It is recommended that Brake Caliper should be inspected and maintained frequently to avoid cases like leakage, premature wearing of the Brake Caliper or brake drag which compromises the performance of the vehicle.
