Pushing the brake pad -2- slightly into the brake caliper using suitable pliers -1- makes it easier to remove the brake caliper from the brake rotor. To prevent damage to the paint coat on the brake caliper, place a piece of rubber -3- between the pliers and the brake caliper. (Shown on a different brake caliper)
