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

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