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