The low flatbed transport vehicle can be reliably parked by pulling up the parking brake handle. Start the engine and let it idle. Press down the clutch pedal, shift to 1st gear or reverse, and check for any noise or whether the gear shift is smooth. If there is noise or the gear shift is not smooth, it indicates that the clutch of the low flatbed transport vehicle is not fully disengaged. At this point, the vehicle needs to be inspected, including checking the free travel of the clutch pedal, the working condition of the clutch, and the fluid level in the clutch reservoir. By examining these aspects, we can identify the cause and resolve the issue.
After the hydraulic control system of the low flatbed transport vehicle's clutch has been repaired, air may enter the lines; adding brake fluid may also introduce air into the hydraulic system. Once air enters, it shortens the stroke of the master cylinder push rod, which is the working stroke of the pedal, causing the clutch of the low flatbed transport vehicle to not fully disengage.
