First of all the car is an HF CRX with an LS swap, the guy that had the car before me did the swap and used the SI hub on the driver side and I have no idea what the hell he did on the other side

These are the brake pads which hung over the rotor about a 1/4 inch

I'm hoping all I have to do is replace this piece which the brakes fit in, and this brings me to my question whats the name of this peice?


Also the caliper doesnt slide easily up and down after you remove the bottom bolt I have to use all my wieght to move it
