Wow do p-brake in rotor hat systems SUCK if you live in the rust belt and the vehicle has some miles on it.
I know on my 2008 Hyundai Santa Fe, I wound up breaking a bunch of springs, clips and pins on the parking brakes (shoes) during a pad/rotor change. I couldn't 'back-off' the P-brake shoes because the manual adjusters were rusted solid. The only way to get those rear rotors off was to muscle them off. It was highly unpleasant and I had to order a box of little brake parts to put the system back together again. Luckily CarQuest had the kits aftermarket. Otherwise each little part would have to be ordered separately from Hyundai at huge cost.
