Yup, DIY in the driveway.
Not OEM Honda, Rock Auto Parts, didn't totally cheap out, got the midgrade stuff.
Yup, greased the ears and pulled the pins from the new mounting brackets and lubed them up a little more than how they came, wiping off the excess.
All new components, including brackets and verified they weren't rubbing the rotors.
I did a light rub down of the new rotors with brake clean, but they weren't terribly slimy to begin with and have driven about 100 miles on them since so I suspect any goop would've burnt off by now anyway.
I'm at my wits end on this one. I strongly suspect that the right rear caliper still isn't fully releasing, either that or the 100 or so miles of driving with a potentially bum brake hose locking up the caliper cooked the new pads. I'll be taking a longer drive out to the GF's place tomorrow, about an 80 mile round trip, so I'll see how it behaves. Maybe I just have to wear off whatever burnt bits could be on the pads. Might try swapping out pads again too, they're cheap for this car.
