ATE Rear Wheel Cylinder 020173

The wheel cylinder is a key component of a car's braking system. It is responsible for applying hydraulic pressure to the brake shoes, which in turn presses them against the brake drum to slow down or stop the vehicle. The wheel cylinder is typically located at each wheel and is connected to the brake lines, allowing brake fluid to flow in and out as the brakes are applied and released.

When the brake pedal is pressed, the wheel cylinder uses the hydraulic pressure from the brake fluid to push the brake shoes against the drum, creating friction and slowing down the rotation of the wheel. This action is what ultimately brings the vehicle to a stop. The wheel cylinder plays a crucial role in ensuring that the brakes function properly and effectively, making it an essential part of the overall braking system in a car.
