Your Geo vehicle is outfitted with top quality parts that enable it to perform very impressively on road. And among the top quality parts incorporated into your beloved Geo driving machine are the components making up the braking system which can either be disc braking system or a drum braking system. Two of the most important components of your vehicle's disc braking system include the brake caliper and the brake disc or rotor; while the drum baking system includes the brake drum and the brake shoe as its most important components. Also, a wheel cylinder like the Geo wheel cylinder is an integral of the drum brakes. This wheel cylinder features movable pistons that change the hydraulic fluid pressure into mechanical force which powers your engine. The said pistons move the brake pads in your vehicle against the braking surface of the drum. As you press on the brake pedal, the Geo wheel cylinder pistons move within the master cylinder thereby forcing the brake fluid through the brake lines and into the cylinders of each wheel. The hydraulic brake fluid that is under pressure basically causes the pistons of the wheel cylinder to move which then forces the brake pads against the brake drum. Hence, excellent and reliable slowing down or stopping power of your vehicle's motion. But because of the constant use of the brakes, the wheel cylinder can be expected to malfunction in time.
