My 0.02:
- make sure pads bracket is well cleaned and if surfaces mating with stainless slide inserts are rusty and 'swollen' then remove rust and make sure inserts ('hardware') sit all way in. I put grease between bracket and inserts, no grease between insert and pad ear. If you really have to add lube between inserts and pad ears then you can use graphite dry lube which is actually powder.
- Power Stop parts quality is a bit of hit and miss; I did brake job on a '18 F30 and one rotor had set screw hole without bevel, had to fix it as opposed to return/replace on the parts
- my go to rotors and pads lately are Bosch QuietCast, used to like Raybestos till about 1.5 years ago and Power Stop till about 6 months ago.
