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

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