My Alfa is 3 .5 years old and has only 67000 kms on the clock. Last month I started the car and depressed the cluch enged first gear and while waiting for passengers to climb in it felt like the cluch was engaging and as I had my foot on the brake it stalled. When I took my foot off the cluth it stayed on the floor board. After a bit of cursing I pulled the pedal up with my hand and low and behold it was normal. It was a little soft but it worked. I travelled over 300 kilometers in that week without trouble but have recently felt that the clutch was losing pressure again so I simply slip the car into neutral pump the clutch and off I go. This afternoon the clutch stayed down again. I flipped it back up with my tow and off I went again. I have been told I need to service the master cylinder only to be told that master cylinders are not serviced, they are simply replaced. Is this right and has anyone had a similar problem?
