Proper braking operation of your Oldsmobile is highly crucial for your safety on the road. This is for the fact that the braking system is the one responsible for stopping or slowing down your moving vehicle. It absorbs the kinetic energy of the moving vehicle and converts it into heat so as to accomplish an efficient braking action. When you apply force to the brake pedal, you are putting a massive stopping force that is much greater than the force that puts your vehicle in motion. Typically, the brake system is consists of disc brakes used in the front wheels and drum brakes on the rear wheels. They are connected via series of hoses and tubes that couples the brake at each wheel to the master cylinder. On drum brakes, the hydraulic fluid is directed through the Oldsmobile wheel cylinder under pressure. This in turn, allows the brake shoes to move and press against the drum causing the wheel to stop. The drum brake system is composed of the backing plate, brake drum, brake shoes, return springs, and automatic or self-adjusting mechanism. All these components work in perfect concert with each other to successfully execute peak braking performance. The Oldsmobile wheel cylinder is made up of a cylinder outfitted with two pistons that are connected in each of its side. Every piston is equipped with a rubber seal along with a shaft that couples the piston to the brake shoes. When pressure is applied, the pistons are forced out, moving the brake shoes against the drum. In time, the wheel cylinders may decline in efficiency due to its normal aging and in some cases, signs of wear and leaks may show. When this occurs, replacement should be acquired.
