Try to post a bright clear picture of the side . Like above but so we can see how you have it in the bracket. It looks like you dont have up against the bracket correctly. It only takes 1 spring per caliper. If you have the old caliper us a pair of calipers to measure the old and new and see if there is any difference. Where do you have the wedge in your picture in the top of the picture or the bottom? Where it is touching the rotor need to be pryed outward. before the key and spring is installed. You are making it harder than it needs to be to help.
