When a caliper on the Mercury Mariner seizes, leaks, or drags, the damage does not stop at the caliper. A partially seized caliper on your Mariner keeps the brake pad in continuous contact with the rotor, wearing the pad unevenly and scoring the rotor surface. By the time the caliper on the Mercury Mariner is identified as the fault, the pads are typically worn asymmetrically and the rotor is damaged. A caliper kit from GeoBrakes addresses every compromised component on your Mercury Mariner together.
The kit for your Mercury Mariner includes the disc brake caliper at the correct left or right hand specification for the Mariner, either new OEM-spec or quality remanufactured to the Mercury Mariner piston dimension and hydraulic pressure rating, brake pads in ceramic or semi-metallic formulation matched to the Mariner caliper and rotor specification, caliper hardware with slide pins, pin boots, and anti-rattle clips for correct caliper float on the Mercury Mariner, brake lubricant for correct pin and shim installation on your Mariner, and copper washers or banjo bolt seals for the brake hose connection where required by the Mercury Mariner application.
A caliper kit is the right call for the Mercury Mariner in three specific situations. After a seized or dragging caliper, because the pads and often the rotor on your Mariner are already compromised. During a high-mileage Mariner overhaul at 150,000 kilometres or more, because caliper piston seals and guide pin boots on the Mercury Mariner are typically at or beyond their service life. After a brake fluid leak at the caliper, because fluid contamination of the Mariner brake pad renders the friction material permanently ineffective on your Mercury Mariner.
New OEM-specification calipers for the Mercury Mariner are manufactured from fresh materials with no prior service history, the strongest choice for Mariner vehicles in high-corrosion environments. Remanufactured calipers use original Mercury Mariner housings rebuilt with new pistons, seals, and boots, performing identically to new units at a lower price point for most Mariner replacement applications.
Calipers for the Mercury Mariner are the most position-specific brake component in the catalogue. Left and right calipers for the Mariner are not interchangeable. Our vehicle selector confirms the correct caliper kit for the Mercury Mariner exact year, axle position, and left or right side before purchase.
Should I replace both calipers on my Mercury Mariner at the same time?
It is strongly recommended. If one caliper on the Mercury Mariner has seized or leaked, the caliper on the opposite side has experienced the same conditions and age on your Mariner. Replacing both restores balanced, even braking and eliminates the risk of the second Mariner caliper failing shortly after the first is replaced.
Do I need to bleed the brakes on my Mercury Mariner after installing a caliper kit?
Yes. Opening the hydraulic circuit on the Mercury Mariner to install the new caliper allows air to enter. After installation, the brake circuit on the Mariner must be bled at the caliper bleeder screw to purge all air and restore a firm, consistent brake pedal on your Mercury Mariner.
What is the difference between a new and remanufactured caliper in the Mercury Mariner kit?
A new caliper for the Mercury Mariner has no prior service history and is the stronger choice for high-corrosion environments. A remanufactured caliper uses an original Mariner housing rebuilt with new pistons, seals, and boots, performing identically to new at a lower price point for most Mercury Mariner applications.
