So i had a friend help, he got my bearing out by pure magic, but set ut where i couldnt see it. Long story short, got so dirty there was dirtand grit along with rust. Being poor, only solution i had was liquid bar leepers friend, PB blaster and a dremmel with a soft brush. 2 meticulous hours later its clean, smooth, no resistance or grinding sound at all. But i have a replacement just in case. Its not going nuclear... I hope. But it probably needs replacing right? I dont care about the work, its the cost at the moment. Should i suck it up, and yeah $13 is a lot for me. But is it dangerous?li looks brand new. but itozo e says replace. However that wasn't their Toyota guy.

The left one is the one I cleaned

 

It depends. You need to either get a bearing greaser, costs money, or at the very lest, press some new grease into the bearing by hand. Cup your palm around a section of the bearing, squeeze some grease out of your grease gun onto your thumb, and press it down onto the inside of the portion of the bearing that's cupped into your palm. Do it again, and again, until the grease is squishing out the other side of the rollers. Do that all the way around the bearing's circumference. It's messy, but actually pretty easy. You'll need to do it to the new bearing anyway.
Now, hold the bearing only by the rollers with a couple fingers and the thumb of one hand, grip it by the outer metal with the other hand, and roll it around. All the way around. It should roll easily, but much more importantly, SMOOTHLY. And slight catch to it, or grinding, ANYthing but a smoooooooth rotation, bad bearing. It must be replaced. If you don't replace a bad bearing, it will grenade itself sooner or later. More likely sooner than later.

If it feels good, heck, put it back in! Go ahead and reuse it.

Hope this is some small help.

I would probably blast those bearings with brake parts cleaner until they are really clean, and if there isn't any obvious wear problems or damage, re grease them. You can use a bearing packer or do it by hand to regrease the bearings.

 

Then I cleaned it with barkeeper friend then more brake cleaner bar keeper friend and then finally I said you know what screw it because I kept on finding more rust. It felt completely smooth to me but I figured barkeeper friend is technically an abrasive so I better not risk it no matter how fine of an abrasive it is which is like crazy cuz it's liquid. So I got new ones and now I can't get the damn brake piston dust boot back onto the caliper. And I don't remember if they're supposed to be an o-ring here.

But I am pretty damn sure that I did put silicone on it, damn YouTube. Or actually I should say damn my assumption is just any old silicone lube. Swiss Navy, ha! Naw, kidding. PB Silicone, I'm not sure if that's what warped it or if it's just that old. And it though wasn't till later that I saw that you should only use brake fluid.

Now am I missing an o-ring here some sort of seal now I'm terrible at putting every part in the back in the box. I returned the ceiling gasket kit. But it just so happens I have two that are almost looking like they can fit but don't unless I stretch the hell out of them. They're not the piston ring though.

After a couple of weeks at my almost done with my screw up and I can get back to working on the electrical. That is finally I'm sucking it up and going to do the math. I had to get a makeshift white board so that way I can actually see every calculation per circuit. Don't have to flip through cell phone pages, or laptop windows. I've been avoiding that.
