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

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