In addition to reducing friction, hydraulic piston oil seals also help maintain the cleanliness of the hydraulic fluid. By sealing the piston chamber, these seals prevent dirt, debris, and other contaminants from entering the system and causing damage to the hydraulic components. This is particularly important in industries where hydraulic systems are exposed to harsh environments or heavy use.

Another important feature of drum brakes is the wheel cylinder, which is located at the top of the brake assembly. The wheel cylinder contains two pistons that move outwards when hydraulic fluid is pressed into the cylinder. This movement causes the brake shoes to expand and press against the drum. The design of the wheel cylinder is crucial, as it ensures even distribution of pressure on both brake shoes, promoting uniform wear and effective braking.
