Brake pedal rod for master cylinder - which to use?

I have on a couple of occassions had to use a die grinder and cut the piston from around the rod. After many years of crud building up there, plus brake fluid possibly leaking onto the collar and swelling it they are a real pain in the butt.

Magnum HP and Year one both have the collars.

This is how I got the rod out:

Used a 1/2" threaded rod, or bar stock about 18" long thru the eye hole. Cut a block of would about 1/2" longer than the distance between the back of the flange and the bar. Clamp the master in the vise, and pry. The rubber collar usually come with a new master. You must use it!

I never put the boot back in.
