The Parking Brake Piston converts hydraulic applied pressure into a linear mechanical force that engages and disengages the brake disc. A parking brake is applied, and the piston extends and retracts to press brake components against a disc, locking the drivetrain and preventing equipment movement. It functions reliably under varying pressure conditions and maintains brake engagement even during prolonged stationary periods.Attributes:• Provides hydraulic actuation for applying and releasing the brake mechanism.• Supports controlled braking action during equipment stoppage and holding.• Withstands repetitive pressurization cycles without deformation or fatigue.Applications: The Parking Brake Piston is used in the parking brake system of hydraulic-powered equipment. It is mounted within the brake assembly to engage and disengage braking components, helping hold equipment in a stationary position during parking and idle operation.
