Clutch Master Or Slave Cylinder Information

WARNING: This page is about a different car, the 2010 Audi A5. However, it is still accessible from the selected car via links, so may be relevant.

If the clutch master or slave cylinder must be replaced because it is faulty, run a function test first. Refer to CLUTCH MASTER CYLINDER AND CLUTCH SLAVE CYLINDER, FUNCTION TEST .
If the slave cylinder is removed from the transmission with hose/line assembly connector, do not operate (depress) clutch pedal any more. Otherwise, the pistons are pushed out of the clutch slave cylinder and thus damaged.
Carefully actuate the clutch pedal after installing the slave cylinder. If an abnormally difficult pressure point is noticed when depressing the clutch pedal, do not depress the clutch pedal any further. The plunger of the slave cylinder was probably guide past the clutch release lever. Beyond a pedal force of approximately 300 N, slave cylinder is destroyed.
