Dot 3 or 4 fluid. J-Auto is a good source for brake pads and fluid- J-AUTO - Bushings, Suspension, Parts for Mazdas
They bleed just like any other car- RL,RR,FR,FL

Thta looks like a beautiful FD, keep it stock! If you want to modify one sell that on Bring A Trailer and buy one that is lightly modded already and make it ridiculous.

“Speed bleeders” can help if your working alone. I’m about to to use a Motive brake bleeder on mine.
J-Auto is a good site for things, but if it’s a street driven car you don’t need the racing fluid IMO.
If it’s a LHD car I think I’d start with the RR first since it’s farthest away from the master cylinder.

Free downloadable Factory Service Manual for your car —-> http://wright-here.net/cars/rx7/93_manual.htm
All the specs for ALL fluids will be in there.

I'm a big fan of the Motive pressure bleeder - one of my favorite tools in the shop! Makes brake bleeding a simple & quick one man job. The only problem I had with mine is the basic Motive kit didn't include a good cap for my FC. The "universal" cap contraption they provide is very cumbersome and barely fits on an FC, so I ended up making my own cap adapter with a spare brake master cylinder cap, a barbed hose fitting and some epoxy.

If the manual says you can use DOT3, then DOT3 or higher is ok in the same family. If the manual says DOT4, you can't go down to DOT3 etc.. Also, you can't mix formulations with silicon with those that do not have silicon. I like MOTUL 5.1 https://www.motul.com/us/en-US/produ...-1-brake-fluid

While we’re on the subject....KansasCityREPU,
with new brake pads, 2 liters (4-500 ml bottles) should be plenty....right?

1 500ML bottle is enough for a pad change and bleed, get two if you want to have extra.

Huh...would've guessed I needed more, but confess it's been a while since the last time I did it. Thanks.

As far as fluid amount goes, if all I'm doing is a quick pad change & bleed, a 16oz or 500mL container is enough to get the job done. But when I want to fully flush ALL of the old fluid out, to the point where nothing but pure clear fluid flows out the bleeders, it will take a 1 quart or 1 liter container of fluid. That's on an S5T2 with the ABS removed, and using a Motive pressure bleeder.
