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

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