Just did this last week. It was my first YC bracket replacement job. It was super easy to break the brackets in this piano. I used a long punch. I'm guessing it's a nail punch and it's about 9 inches long. I picked it up last year in a tool purchase at an old auto parts place. You could use anything similar. Simple impact engineering! Haha. The brackets on mine broke very easily. I wouldn't bother with trying to get any saw in there unless yours don't break easily. (I brought stuff with me just in case.)
This piano apparently had multiple adjustments over the years, as it was incredibly unregulated after the bracket replacement. It took about 8 hours for the replacement and regulation, and a bit less than two hours for the 50-60 cent pitch raise and tuning (tuned 3X).
To aid in a "stuck action" removal, I first tried to slide it out with a thin sheet of polycarbonate placed over the hammers (bought at Lowe's for $3.00 from their leftover "scrap" section.) You could also use a thin sheet of metal or cardboard. Whatever sheet you use, it tends to force the hammers and drop screws below the pinblock. Just didn't work for this piano so I broke the brackets.
There are instructions here in the files. Go to the Pianotech list and look in the Library. It's all the way at the bottom under "YC brackets" or some such name.

Hi All, I have just been contacted by a client who needs to have the brackets replaced on his 20yr old YC G-150. I will go to see the piano in a couple of days.
1) He says the action is frozen into the piano and has been advised that it will be necessary to break the old existing brackets in order to get the action out. Has anyone who has done this bracket replacement before encountered this? Where and how did you break the brackets? Any details will be much appreciated.
2) The owner says that he already has the replacement brackets, so no issue of ordering them. But I am wondering about how much time it has taken people to install the replacements and get the piano working properly.
All of your comments will be much appreciated.
Thanks,
David
