Uneven. Brake pad wear

On both front caliper the inside brake pads are either worn rite down or missing while the outside pads looks fine !

Looking to order all the parts I need.. Any idea why this would happen ?
Also both front caliper are new last year

sounds like the pins need a good greasing. I use this stuff called silaramic by CRC. clean em out the best you can, and use a light amount of grease to keep the pins sliding.

Basically what is happening is one of two things. you hit the brake and the piston pushes the inside pad against the rotor, and the pins are stuck and not pulling the opposite piece against the outside pad.
or the piston pushes the inside pad to the rotor and the outside pad gets pulled into the rotor, and when you let go of the break, the pins get stuck and hold the inside pad against the rotor.

otherwise the piston is not decompressing and the calipers are defective.

As fenixignition mentioned, it could be just the pins or caliper problems. It can also be caused by hydraulic issues. Have you had your ABS light come on before...then go off while driving? Have you inspected the brake lines to make sure there are no bends or crimp that could be restricting the hydraulic fluid and is the master full?

Classic slide pin or one of the pistons isn't working in the front calipers. However if its both sides the likelihood of both calipers being bad is low. Slide pins routinely get gummed up tho if they aren't greased every time the brakes are done. I always do. Do the brakes, use good rotors like Raybestos, make sure you compress both pistons properly, remove and grease the slide pins, new rubber boots if you need them on the pins and then bleed the brake system.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
