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

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