GeoBrakes carries OEM-grade drum brake wheel cylinders confirmed to fit the Mercury Tracer, the hydraulic actuators at the top of each drum brake assembly that convert brake fluid pressure into the mechanical force that pushes the Tracer shoes against the drum. Available in new and remanufactured options for your Tracer, every cylinder is bored to OEM specifications

The drum brake wheel cylinder on the Mercury Tracer is the hydraulic component that actuates your Tracer drum brake shoes every time you press the brake pedal. Brake fluid pressure from the master cylinder enters the Tracer wheel cylinder and acts equally on two opposed pistons, pushing them outward simultaneously toward each shoe on the Mercury Tracer. A leaking Tracer wheel cylinder actively bleeds hydraulic pressure from the brake circuit and contaminates the brake shoes with fluid, both of which directly compromise your ability to stop the Mercury Tracer.
Mercury Tracer drum brake wheel cylinders are particularly vulnerable to corrosion in American road salt conditions. Salt water penetrates the dust boots over time on the Tracer, attacking the cylinder bore surface. Once the Mercury Tracer bore is pitted, new piston cup seals cannot maintain a leak-free seal. Internally corroded Tracer cylinders must be replaced, not rebuilt. Vehicles in high-salt urban environments often require Tracer wheel cylinder replacement on the same service interval as brake shoes.
GeoBrakes stocks both new OEM-specification wheel cylinders and quality remanufactured units for the Mercury Tracer. New cylinders are the stronger choice for Tracer vehicles in high-corrosion environments. Remanufactured units offer excellent value for Mercury Tracer vehicles in moderate conditions where the original bore was sound. Our vehicle selector confirms the correct Tracer cylinder, right bore diameter, port location, and mounting configuration, for your Tracer drum brake assembly before purchase.
Can I drive my Mercury Tracer with a leaking wheel cylinder?
No. A leaking Tracer cylinder actively loses hydraulic pressure from the brake circuit, reducing stopping force on your Mercury Tracer over time. Brake fluid that reaches the Tracer shoes renders the friction material ineffective. A leaking Mercury Tracer wheel cylinder is an immediate safety concern that requires urgent attention.
Should I replace both wheel cylinders on my Mercury Tracer at the same time?
Yes. If one Tracer cylinder has leaked or seized due to age and corrosion, the cylinder on the opposite side of the Mercury Tracer has experienced identical conditions and is at a similar stage of deterioration. Replacing both ensures balanced hydraulic pressure on your Tracer and avoids a second service call within months.
Do I need to bleed the brakes on my Mercury Tracer after replacing a wheel cylinder?
Yes. Replacing a Tracer wheel cylinder opens the hydraulic circuit, allowing air to enter. After installation on the Mercury Tracer, the entire rear brake circuit must be bled to remove all air and restore a firm, consistent brake pedal on your Tracer.
