The Parking Brake Control Knob engages and disengages the parking brake unit in a machine. When the knob is pulled or engaged, it activates the parking brake mechanism, applying pressure to the machine's rear brakes and preventing the machine from rolling or moving when parked. This helps to securely hold the machine in place on inclines or when parked for extended periods. Conversely, when the knob is pushed or disengaged, it releases the parking brake, allowing the machine to move freely.Attributes:• Resistant to environmental factors, such as temperature fluctuation• Provided with a comfortable grip and ergonomic shape, providing ease of use and reducing driver fatigue during operationApplications:The Parking Brake Control Knob provides a convenient way for operators to control the parking brake unit, ensuring the safety and stability of the machine while parked.
