I don't know your specific car but the description in the DIY section should cover it. You need the sensors with the pads and the paste. Once the pads are out, look at the inside of the caliper and clean off the brake dust. (I wear a scarf around my mouth and nose to protect my lungs from fine dust.) It makes the insertion of the new pads easier. Inspect the insides for damage to rubber seal. Sometimes a spring might be broken. Dealer normally has it.
I loosen the bleeder nipple when pushing back the pads to make it easier and you are going to replace the fluid anyway with your power bleeder afterwards. Its easiest with the car on stands as you can bleed all four calipers at the end together. The brake fluid is aggressive on paint, so watch out for that.
Easy on the paste. It gums up the rubber seal.
It's the unexpected like uneven pad wear (stuck caliper) or a broken dust seal that can make it more challenging, but if everything is ok, then the pads are really easy.
