Got a question about the size of the front and rear brake pads. About a year ago i bought some new rotors cause the fronts had heat spots and were fairly beat on by me. So i decided to replace all the rotors with cross drilled ones and i replaced the rear ones with some the same size as fronts (they didn't have different size rotors for the front and rear). Now the pads in the back are smaller than the front so there is this strip on the very inner of the rotor that doesnt get any contact and you can see the difference.

On to the question, would the front pads actually fit on the back (now that i have a bigger rotor) or is the brake caliper actually not big enough to hold a bigger pad?

 

the calipers are different size, so no, rear calipers won't fit the front pads

 

The rears are about 60% the size of the fronts..
I wonder if its possible to get calipers from the fronts and put them on the rears.

 

You can't bolt the front rotors on the rear of the car. They won't fit between the pads and they would hit the outer portion of the caliper. The OP is clearly mistaken.
