535 vs M5 clutch master cylinder
Can I interchangeably use either of these master cylinders on my 92 535iM?
535i part# 21521155425, D=19,05MM
M5 part# 21522226477, D=19,05MM
They have the same bore size so what is the difference?
Is there more travel on the M5 one for the bigger bore on the M5 slave?
It seems the pedal should make either travel the same if it the attachment arm length does not change.
Also, is the master cylinder push rod supposed to feel like it disconnected internally at the other end when I have the master out of the car?
Thanks
