Mark,
I had a feeling it was not a rust thing.
Good and bad to hear the same.
Never used prying, just pulling.
I just cut them off and press out the remaining shaft and replace with a new one.
Once I have stainless hardware on the slave cylinder, I can remove and replace the unit easily.

I live where vehicles don't rust. The notion of that lever easily
popping off is foreign to me too. I'm sure some do but seldom the ones I
need to remove. I have used prybars/hammers, pullers after welding on
tabs, propane torches, sawsalls, etc.

>> in 13 mm.
>>
>> Removing the Slave cylinder entirely from the topside is possible,

>> the banjo fitting at the slave cylinder, which is a bit tricky if you

>> about introducing air into the system).
>>
>> The most difficult thing about reinstalling the new unit (which I

>> crank it down about 1/2 way by pushing the slave down against its
