GeoBrakes carries OEM-grade drum brake wheel cylinders confirmed to fit the Pontiac Wave5, the hydraulic actuators at the top of each drum brake assembly that convert brake fluid pressure into the mechanical force that pushes the Wave5 shoes against the drum. Available in new and remanufactured options for your Wave5, every cylinder is bored to OEM specifications

The drum brake wheel cylinder on the Pontiac Wave5 is the hydraulic component that actuates your Wave5 drum brake shoes every time you press the brake pedal. Brake fluid pressure from the master cylinder enters the Wave5 wheel cylinder and acts equally on two opposed pistons, pushing them outward simultaneously toward each shoe on the Pontiac Wave5. A leaking Wave5 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 Wave5.
Pontiac Wave5 drum brake wheel cylinders are particularly vulnerable to corrosion in American road salt conditions. Salt water penetrates the dust boots over time on the Wave5, attacking the cylinder bore surface. Once the Pontiac Wave5 bore is pitted, new piston cup seals cannot maintain a leak-free seal. Internally corroded Wave5 cylinders must be replaced, not rebuilt. Vehicles in high-salt urban environments often require Wave5 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 Wave5. New cylinders are the stronger choice for Wave5 vehicles in high-corrosion environments. Remanufactured units offer excellent value for Pontiac Wave5 vehicles in moderate conditions where the original bore was sound. Our vehicle selector confirms the correct Wave5 cylinder, right bore diameter, port location, and mounting configuration, for your Wave5 drum brake assembly before purchase.
Can I drive my Pontiac Wave5 with a leaking wheel cylinder?
No. A leaking Wave5 cylinder actively loses hydraulic pressure from the brake circuit, reducing stopping force on your Pontiac Wave5 over time. Brake fluid that reaches the Wave5 shoes renders the friction material ineffective. A leaking Pontiac Wave5 wheel cylinder is an immediate safety concern that requires urgent attention.
Should I replace both wheel cylinders on my Pontiac Wave5 at the same time?
Yes. If one Wave5 cylinder has leaked or seized due to age and corrosion, the cylinder on the opposite side of the Pontiac Wave5 has experienced identical conditions and is at a similar stage of deterioration. Replacing both ensures balanced hydraulic pressure on your Wave5 and avoids a second service call within months.
Do I need to bleed the brakes on my Pontiac Wave5 after replacing a wheel cylinder?
Yes. Replacing a Wave5 wheel cylinder opens the hydraulic circuit, allowing air to enter. After installation on the Pontiac Wave5, the entire rear brake circuit must be bled to remove all air and restore a firm, consistent brake pedal on your Wave5.
