2007 Mazda 3 Brake Parts

First the calipers are of high quality construction and it is nicely painted but the bolt holes on the bracket are way too small. I took my old calipers off because they were done, thought this would be a nice upgrade and they are don't get me wrong. My disappointment was I wasn't able to use the entire setup I had to recycle the old unpainted bracket instead of using the painted one that came with the calipers. The drilled and slotted rotors are also nicely made. It could be me or just the supplied brake pads but there is a lot of brake noise when stopping not metal on metal like when your brake pads are done, just a low grumbling grinding noise not what you would expect from a brand new setup calipers rotors and brake pads.
