A throw-out bearing is a key part of the vehicle’s clutch system that disengages the vehicle’s engine from the transmission on a temporary basis during the gear shifts. When it fails, you will hear different noises when you depress the clutch pedal. Vibration of the clutch pedal, gear shifting issues, stiff clutch pedal- are the signs of a defective throw-out bearing. It will soon get to a point where you fail to disengage your Mini’s clutch. Consult a service specialist to get your Mini inspected and restore your adorable Mini’s performance.
