The problem we had was that when trying to get the snap ring off, my snap ring pliers weren't holding onto the snap ring, they would start opening up the ring and then they would pop out. This was because the little pins that form the nose of the pliers had lost the little groove at the end that is supposed to get under the snap ring when you push them into the holes (worn out). This kept happening and I just couldn't get the snap ring to stay on the pliers when trying to pull the ring back onto the shoulder of the cylinder.
The trick we used to get the snap rings off (I ended up taking both off) was a two person job. This only works if you are discarding the old slave (not rebuilding it). One person spread the ring and the other person jammed a small (expendable) straight blade screwdriver into the gap where the ring has started to open. Then one person holds the screwdriver in place while the snap ring pliers are taken away. So now you have the ring spread a little with the screwdriver holding the gap open. Then you keep pushing the screwdriver into the gap while using slip joint pliers to rotate the slave cylinder. If you do this right the screwdriver will act like a wedge, pulling the ring up onto the shoulder on the slave as the cylinder is turned. Once you have about 1/4 to 1/3 of the ring then it will stay there without the screwdriver and you can use pliers to complete the removal.
Since I never rebuild slave cylinders this would be my standard method, at least until I see some snap ring pliers that I think work better.
