Customer Question

Occasionally the clutch pedal goes to the floor on a cold morning start up. It returns after the engine starts. Full of fluid. What could it be? adjustment or master or clutch cylinder?

Hello, there is no adjustment so rule that out,A slave cylinder can not cause this unless leaking, Most common is the master cylinder, The seal cups inside when cold shrink, and if old and worn, fluid will bypass them and pedal drops to floor, When warm the seals expand and do their job and you get pedal back, I am near 100% you need to change the master cylinder
