It's a fairly simple job! You have to remove the cable for the handbrake and remove the lower bolt that attaches the caliper and swing the caliper upwards which releases the pads and anti-noise shims. You will have to push the pistons back into the calipers before mounting the new pads and shims. Make sure you put some suitable brake grease on the back of the pads and shims (a very light coating only!) to avoid squeeking. Replacing is the reverse of the dismantling. Good luck
