NOTE:

Pushing on the inner brake pad lightly with pliers -1- makes it easier to remove the brake caliper from the brake rotor. To prevent damage to the coating on the brake caliper and to the brake pad wear display contact, place a piece of rubber -2- or similar between the pliers and the brake caliper. While doing so do not damage the brake pad wear indicator cable.
