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

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