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

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