I used to do my own pads and rotors as well. It's pretty quick to do yourself, especially if you are familiar with the vehicle you're working on. I used to have a Toyota Hilux, and on that truck the brake rotor actually forms part of the housing for the front wheel bearings, meaning when changing rotors you either had to repack or replace the wheel bearings. It wasn't too bad but an extra step few people have to deal with.
That actually not a super uncommon design for older disk brakes, and stuck around a long time on light/medium duty pickups also.
I'm guessing it probably had fixed(as opposed to floating) calipers. I like them a lot better, although they are of course more expensive. In theory I also like being able to change pads without removing the rotors(which most designs allow) but I've never seen a practical need to do it and deal with having to retract pistons.
I do have to admit also that even though pulling the hubs to change the rotors is a royal pain, I like the idea of the rotor being bolted to the hub rather than "sandwiched" between the wheel and hub and hanging off the studs.
And of all the things I find myself up for with this timely post-my brother in law has decided he wants to learn to work on cars and I told him I'd call him when I was working on something and he could come over if he wanted. I called him today to ask if he wanted to come over and change the oil in the MKZ with me(start simple) or if he really wanted to learn esoteric and mostly useless on modern car skills, if he wanted to do the spring tune-up and lube on the MG with me.
Turns out his brakes are metal on metal and his fiancé had said she could help him change them using his 5-socket tool set she gave him as a birthday present. He asked if they could come over and do it in my garage, which I said was fine as long as I was supervising(my tools, my house, my rules). We are going shopping for parts tomorrow afternoon and then going to do them. Just hoping that we don't end up with "too many cooks in the kitchen" so to speak with his fiancé there also. To her credit, her dad DID teach her a lot of car maintenance basics, but she also says it's been 5+ years since she's touched anything and, there again, my garage and all.
Fortunately I'm not too worried about anything crazy on a 2010 Camry...
