Поршень тормоза заднего моста Caterpillar 8I3883

The Rear Axle Brake Piston acts as a pressure-responsive component that transforms hydraulic brake fluid pressure into the mechanical force required to push the brake pads against the brake shoes against the drum. The hydraulic pressure builds within the brake cylinder, and the piston moves outward, generating friction that slows down the wheel rotation. During braking release, the piston retracts to allow free wheel movement.Attributes:• Enhances overall braking efficiency by ensuring complete force transfer.• Provides long operational life with minimal maintenance needs.• Supports balanced braking pressure between rear wheels.Applications: The Rear Axle Brake Piston is installed within the rear brake assembly to convert hydraulic pressure into braking force, enabling effective rear wheel deceleration.
