First and foremost, we bolted the caliper bracket to the spindle as per the directions. These will actually bolt up quite a few ways, but only will work. Make sure that the caliper is positioned up towards the fender, and to the back of the car. We lubricated all bolts upon installation and ensured that the mating surfaces were properly snug. This is most important on any disc brake assembly as a small misalignment will cause an angle of contact between the rotor and pad and ultimately, lead to poor braking and an uneven wear pattern.
