It's a 1983 633 Csi with 220000 miles on the original engine.
The clutch pedal was spongy and I replaced the master and the slave
cylinders then bled the
system. For about 6 months I didn't have any problem then the clutch
pedal started to stay
on the floor and didn't come back. In order to use it again I had to
pull the pedal up and
wait about 5 - 10 minutes. When the problem showed up more frequently
I thought that the
parts were defective and replaced both of them one more time. These
new parts acted fine for
about 4 months and the problem appeared again.
I took the car to a mechanic. They checked the parts and found nothing
wrong with the clutch
hydraulic system and offered to bleed the system that didn't change
I wonder if anyone had such a problem in the past and how solved it.
Or does anyone has any thought about it.
Only two other things that I can think of are:
a) The clutch system (the pressure plate) has a problem and moving
somehow. By the way I
have 125000 miles on the clutch but it's not slipping at all.
b) The crank is moving back and forth moving the clutch assembly
together. This is a
known problem with some Mitsubishis but not with BMWs.
I would appreciate anyones opinion.
