Very easy to replace the pads. Remove the pins slide a wide thin wedge in between the pads and the disk, to give the new pads some space new pads in and replace the pins. Just be careful with the brake fluid as it will be forced back into the reservoir and could over flow. Get yourself a syringe and take some of the fluid out before starting and top up after the job is done.
