Your Pontiac Grand Am rear drum brakes rely on the wheel cylinder to convert hydraulic pressure into the mechanical force that pushes the brake shoes against the drum. When the wheel cylinder on your Grand Am leaks, seizes, or develops a soft piston seal, the rear brake circuit is compromised on that corner. A complete wheel cylinder kit from GeoBrakes restores every hydraulic component at that wheel simultaneously, delivering a brake circuit that holds pressure reliably through the next service interval on your Pontiac Grand Am.
The most common drum brake wheel cylinder mistake is replacing the cylinder on a Pontiac Grand Am while reusing worn dust boots and deteriorated cup seals. In American conditions, where road salt attacks rubber components and corrodes bore surfaces on the Grand Am, a new cylinder fitted with old boots is a failure waiting to happen. A complete wheel cylinder kit ensures every hydraulic component at that wheel is renewed together, regardless of whether the Pontiac Grand Am has accumulated 80,000 or 180,000 kilometres of American road use.
Kit contents are specific to the Pontiac Grand Am application and bore specification. A complete kit for your Grand Am includes the wheel cylinder at the OEM bore diameter for the Pontiac Grand Am, piston cup seals preventing fluid bypass past the pistons, dust boots protecting each piston end from road salt and moisture infiltration common in American winters on the Grand Am, the internal spring maintaining cup seal contact under low pressure, and the bleeder screw for replacement if the original is corroded from road salt exposure on your Pontiac Grand Am.
Wheel cylinder bore diameter and seal specification must match the Pontiac Grand Am exactly. An incorrect bore size or wrong seal compound produces immediate hydraulic failure on your Grand Am. Every kit in the GeoBrakes catalogue is confirmed for the Pontiac Grand Am year, axle position, and bore specification through our vehicle selector, with both new and remanufactured cylinder options available. New cylinders are recommended for Pontiac Grand Am vehicles with heavy road salt exposure or where the original bore surface was corroded.
Can I rebuild the existing wheel cylinder on my Pontiac Grand Am instead of replacing it?
A rebuild is only viable if the cylinder bore of the Pontiac Grand Am is completely free of pitting and corrosion. In American conditions, where road salt routinely damages bore surfaces on the Grand Am, a rebuild kit applied to a corroded cylinder will not hold pressure long-term. A complete replacement kit is the more reliable and cost-effective solution for most Pontiac Grand Am applications.
Do I need to bleed the brakes on my Pontiac Grand Am after installing the kit?
Yes. Installing a new wheel cylinder on the Pontiac Grand Am opens the hydraulic circuit, allowing air to enter the system. After installation, the rear brake circuit must be bled at the Grand Am cylinder bleeder screw to purge all air and restore a firm brake pedal. Use fresh brake fluid meeting the Pontiac Grand Am specification during the bleed procedure.
Should I replace wheel cylinders on both sides of my Pontiac Grand Am at the same time?
Yes. If one wheel cylinder on your Pontiac Grand Am has failed or leaked, the cylinder on the opposite rear wheel has been exposed to identical conditions for the same period. Replacing both as an axle pair on the Grand Am restores balanced hydraulic pressure and avoids a repeat service call within months.
