Has anyone ever had their master cylinder get messed up using this method? I always hear not to do it this way but when I ask the adviser if they ever had any trouble, they say, "no, it didn't happen to me but..." What do you say? Thank you.

I have had it happen, but only on older and mostly poorly maintained cars. (back in my, "I'll buy it as long as it is under $200", days)
I have always (since the cause of the failure was first explained to me) occasionally push the break peddle all the way to the floor every few times I drive my car. My theory is that this helps keep the master cylinder bore clean and "polished".
I have never had a master cylinder failure on any car since.
