Your Plymouth Pb250 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 Pb250 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 Plymouth Pb250.
The most common drum brake wheel cylinder mistake is replacing the cylinder on a Plymouth Pb250 while reusing worn dust boots and deteriorated cup seals. In American conditions, where road salt attacks rubber components and corrodes bore surfaces on the Pb250, 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 Plymouth Pb250 has accumulated 80,000 or 180,000 kilometres of American road use.
Kit contents are specific to the Plymouth Pb250 application and bore specification. A complete kit for your Pb250 includes the wheel cylinder at the OEM bore diameter for the Plymouth Pb250, 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 Pb250, 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 Plymouth Pb250.
Wheel cylinder bore diameter and seal specification must match the Plymouth Pb250 exactly. An incorrect bore size or wrong seal compound produces immediate hydraulic failure on your Pb250. Every kit in the GeoBrakes catalogue is confirmed for the Plymouth Pb250 year, axle position, and bore specification through our vehicle selector, with both new and remanufactured cylinder options available. New cylinders are recommended for Plymouth Pb250 vehicles with heavy road salt exposure or where the original bore surface was corroded.
Can I rebuild the existing wheel cylinder on my Plymouth Pb250 instead of replacing it?
A rebuild is only viable if the cylinder bore of the Plymouth Pb250 is completely free of pitting and corrosion. In American conditions, where road salt routinely damages bore surfaces on the Pb250, 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 Plymouth Pb250 applications.
Do I need to bleed the brakes on my Plymouth Pb250 after installing the kit?
Yes. Installing a new wheel cylinder on the Plymouth Pb250 opens the hydraulic circuit, allowing air to enter the system. After installation, the rear brake circuit must be bled at the Pb250 cylinder bleeder screw to purge all air and restore a firm brake pedal. Use fresh brake fluid meeting the Plymouth Pb250 specification during the bleed procedure.
Should I replace wheel cylinders on both sides of my Plymouth Pb250 at the same time?
Yes. If one wheel cylinder on your Plymouth Pb250 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 Pb250 restores balanced hydraulic pressure and avoids a repeat service call within months.
