Master Cyl Push Rod Removal

I've read in Mopar Action years ago, leave the rod attached to the brake pedal, then just quickly jerk back on the pedal & the rod will pop right out
It might.

My favorite was to put the master on top of the vice with the vise open enough for the pushrod to fit through. Get a rod or dowel, insert it in the brake pedal end and give it a wack down
