so this is one of my caliper sets, it says L so Im assuming it's drivers side. Do I use all of these pieces? or are they just there as a universal setup for multiple applications?



Here's all the pieces.




I put 1 pad on first, it hangs itself on the grooves of the caliper adapter, then on goes the other pad and caliper body. The outlet for the brake hose is pointing towards the rear of the car, this seems correct.. or do I have the calipers switched?




Then I attached the 2 larger metal plates and bolts, although I dont know which way they are supposed to face




Now I have these pieces left over. what are they for?
