All, about to replace the rotors and pads in the rear of my 2011 LX with OEM. I've ordered the rotors, pads as well as the "Brake Pads Hardware Kit" (04948-60040) also called "Fitting Kit". My supplier (ToyotaPartsDeal.com) has the rotors and pads in stock but the hardware kit is back-ordered with no ETA. Is the hardware kit absolutely necessary or can I reuse what's on the truck now. I'm not 100% sure what is currently on the truck but my guess is it's not OEM as Carmax replaced the pads when I purchased the truck.
