Brake pedal height question

Watched a YouTube video on changing the rear brake pads on a cobra mustang. They used a special tool that turned the caliper piston as opposed to using a C clamp. Seems that the cobra caliper piston ratchets as it moves out. But all they did was spin the piston in to make room for the new thicker pads, no real ‘adjustment’. Is there more to
That sounds like the ones from the 80s. doing more thinking (it's been a LONG time) they auto adjust out as you noted.
Probably not the issue.

Might be a non, issue just something to get used to. Like how some cars have extremely touchy brakes, the first few miles of driving people are tossed thru the windshield but after a while you get the feel for it.
