The other thread doesn't seem so bad to me, though there is conflicting advice. Like I said before, there are a lot of opinions about how to do brakes, but if you find something that works for you then just do that. Some people think it's a risk to work on brakes yourself and only trust a professional to do it since the brakes are kind of critical for safety. But they are simple systems, and as long as you have some mechanical ability and check your work you'll be fine, or worst case you'll find out in your driveway if you did something wrong. And some people are very particular about the way they do things since the brake booster assembly is extremely expensive, but I can't think of hearing about anyone damaging it by bleeding the wrong way. (Some other brands might be more sensitive. I'm not sure if fourwd1 owns a newer Toyota (based on his signature), so he might be writing based on experience with other vehicles.) The worst that usually happens is a bad bleed, then you have to find some other way of bleeding to get the air out. I think one person reported the pump running frequently after bleeding, but that could be air in the system, something damaged by bleeding it, the brake booster getting to the end of its life naturally, or even as simple as increased awareness of the pump noise after paying attention to it. But don't blame me if something goes wrong; do some more research and read more old threads if you have any concerns, then decide for yourself what to do.
A friend of mine used premium Centric rotors, and they seem good. I didn't see any reason to replace my rotors, but I am using Centric Fleet Performance pads with the stock rotors. They mostly work well, but the rears often squeak during light braking. Braking performance feels good, similar to stock. There is more brake dust than stock, but the pads are holding up well. I probably have about 5,000 miles on them now.
