You dont have to remove the calipers even. There are 2 pins with a locking clip and I thin a torx for the shield. They slid out the back.
Sheild comes off first.
Then without maring the rotor push the pads back, that pushes the pistons back.
Pull the clips and pins.
Slide pads out.
Then reverse, pads in pin, clip and shield.
Most important, remember to appy the brakes over and over before first ride. Or you might be in for a suprize. No brakes sux.
