First question, which direction should this clip on the pads face? When removing my front pads for cleaning/wrapping my calipers ( yep, reflective high heat green wrap i posted on my build page), the exterior facing pads had a clip on them, i assume for easier removal. I think i had to press the clip to remove/install the pads. For the rear, when I did my passenger side, I did not take note of the orientation of the clip, resulting in my deciding to position the clip to the exterior of the caliper, matching the front. Upon taking apart my driver side, I discovered the clip was facing interior of the car. For the rear, it does not appear the clip needs to be pressed for installation or removal in either orientation. Does it matter where the clip goes? Do I need to switch the pads back on my passenger side? if it matters for wear pattern, im just over 1k miles. Pics below for clip clarification.

2nd question, the aluminum braces that hold the pads, should they be clean/dry, or oiled/lubricated? I've been cleaning them as I go along but figure i should ask if i should be going back to oil them or something. All clips were dirty, obviously with brake dust, but were not dry to the touch.

That clip is a "cheater" bar. Basically it's a thin piece of metal, you'll notice that the end that points towards the rotor extends to just past the base? When the brake pad itself wears down and it's getting near the end, that little bar starts to touch the rotor and squeals... telling you that you REALLY need to change your pads.

ANY METAL-TO-METAL contact needs to have a little bit of that lube on there with the obvious exception being the pad-to-rotor contact.

That is not the tab that makes the brakes squeal. That can be seen just to the right of it. it rolls over the edge of the pad and hits the rotor when there is about 2mm of brake pad left. I haven't looked close enough at mine to tell you what it actually is though. If I had to guess I would say it acts like a spring to keep the pad in the proper position.

The blue circled one?

I could be wrong because I havent pulled mine off yet, but looking at that pic the piece circled in blue looks to be just something for the pad alignment. The little tab I circled in red looks to be one of the wear tabs that will contact the rotor to make noise when pad material is very low. White Automotive tire Motor vehicle Bicycle part Gas

Naw man, the one in red is just one of the 4 fingers that hold onto the pad itself.

Ah with that link it shows it much more clear. From the angle of the OP pics it looked to be bent in the wrong direction to be a cheater bar. What you cant see is the pin on the other side that points back to the rotor. Good find. 👍

I've changed many a brake, my friend. One might say too many...

The clip circled in red is just part of the shim on the back of the pad. The clip in blue is bent in the picture but it's the wear indicator.
As far as lube, it's a matter of preference. I never lube there. I just make sure it's clean.
