On a slave cylinder operated clutch the slave cylinder (10) is provided with an arrangement for warning when clutch linings are worn. The arrangement incorporates a valve (21) on the inlet line (9) to the slave cylinder. The valve has a free-flowing position and a constricting position. When linings are worn, the valve (21) is caused to assume its constricting position under the influence of a sensor detecting the position of the working piston (13) of the slave cylinder. Application of the constriction makes the clutch pedal become harder to operate, which gives the driver an indication and warning that linings are worn and need changing.
