Market demand significantly influences oil seal prices. In periods of high demand, such as when automotive or aerospace industries experience growth, the price of oil seals can rise. The global push towards electric vehicles (EVs) and advanced machinery can increase the demand for high-performance oil seals, contributing to price variations. Conversely, in times of economic downturn or decline in manufacturing output, demand may decrease, leading to price reductions.
Another important part of the brake drum assembly is the wheel cylinder. Located within the drum, the wheel cylinder is responsible for applying hydraulic pressure to the brake shoes. It consists of two pistons housed within a cylinder. When the brake pedal is pressed, brake fluid flows into the wheel cylinder, pushing the pistons outward and forcing the brake shoes against the drum. This hydraulic mechanism is crucial for delivering consistent and powerful braking force.
