How do I remove a rotor arm to fit a new one?!

[Paddy_g46]

Iv changing my cap and rotor arm today on my valver and i have got the cap off but cannot really see a way or removing the rotor arm other then perhaps pulling it off? Any ideas?

Never had an older reno, but usually they either pull off or could be held on with a screw. If you've bought a new arm, it should be obvious from the look of the new one how it's held on.

Old Cavaliers and BMWs used to just pull off. Sometimes you had to pull quite hard like.
