In a clutch with coil spring how will the axial clamping load vary with wear of clutch facing?

As the clutch facing wears down, the axial clamping load can decrease due to the reduced friction surface area and the potential for the coil spring to lose its preload tension. This reduction in clamping force can lead to slippage during engagement, compromising the clutch's ability to transmit power effectively. Consequently, as wear progresses, the performance of the clutch may deteriorate, necessitating adjustments or replacement to restore proper function.
