Mercury Mountaineer Disc Brake Caliper in US

The disc brake caliper on the Mercury Mountaineer is the hydraulic clamp at the centre of your Mountaineer disc brake system. Every time you press the brake pedal on your Mercury Mountaineer, brake fluid pressure forces the caliper pistons outward, squeezing the brake pads against the rotor and generating the friction that stops your vehicle. A seized, leaking, or sticking caliper on the Mountaineer interferes with that process at the source, causing uneven braking, accelerated pad and rotor wear, and pulling to one side that worsens over time.

Signs of a Failing Disc Brake Caliper on the Mercury Mountaineer

• Mercury Mountaineer pulls strongly to one side during braking, a seized caliper on one side applies more force
• Brake pedal on your Mountaineer feels soft or spongy and improves after pumping, caliper piston seal leaking
• One brake pad on your Mercury Mountaineer axle wears significantly faster than its partner
• Brake drag on the Mercury Mountaineer, vehicle feels like it is fighting resistance at normal road speed
• Visible brake fluid leaking from the Mountaineer caliper body or around the piston boot
• Grinding or scraping from one Mercury Mountaineer wheel that persists after confirming pads are not worn

New OEM-Spec vs. Remanufactured Calipers for the Mercury Mountaineer

New OEM-Specification Calipers for the Mercury Mountaineer

New OEM-specification calipers for the Mercury Mountaineer are brand-new units manufactured to the exact piston dimensions, seal specifications, and material tolerances of the original Mountaineer factory part. They offer the longest service life on your Mercury Mountaineer and are the strongest choice for higher-mileage Mountaineer vehicles or those operated in high-corrosion environments.

Remanufactured Calipers for the Mercury Mountaineer

Remanufactured calipers for the Mercury Mountaineer are original caliper housings completely disassembled, cleaned, inspected, and rebuilt with new pistons, seals, boots, and hardware. Quality remanufactured units perform identically to new calipers for most Mercury Mountaineer replacement applications and offer excellent value.

Frequently Asked Questions - Mercury Mountaineer Disc Brake Caliper

Should I replace brake calipers on my Mercury Mountaineer in pairs?

It is generally recommended to replace calipers as an axle pair on the Mercury Mountaineer, both left and right on the same axle, to maintain balanced braking. If one Mountaineer caliper has failed, the caliper on the opposite side has experienced the same service conditions and is likely at a similar stage of wear.

How long do disc brake calipers last on a Mercury Mountaineer in US?

Mercury Mountaineer calipers typically last 100,000 to 150,000 kilometres, but American road salt and moisture accelerate corrosion of Mountaineer caliper guide pins, slide pins, and piston seal boots, often causing premature failure on the Mercury Mountaineer well before that figure.

Can a sticking caliper on my Mercury Mountaineer damage my brake pads and rotors?

Yes. A Mountaineer caliper that does not fully retract keeps the brake pad in partial contact with the rotor between stops, generating constant friction and heat on your Mercury Mountaineer. This rapidly wears both the pad and rotor surface on your Mountaineer and generates enough heat buildup to damage adjacent components over time.
