It was time to put my winter tires on today and I decided I was going to do my service #2 myself which also included changing my $5 cabin filter and inspecting the brakes and re-lubing the brake caliper bolts. As expected at 17,000km and 11 months the brakes and slide bolts looked pretty much perfect. There was virtually no pad wear on both sets. I am honestly not sure why Hyundai specifies a brake service at year 2. If your going to do this just be careful with the electronic rear parking brakes, unless you have a bidirectional scan tool that can put the car in brake service mode don't turn on the car or try engage the brakes with rear calipers off, otherwise you are going to have some trouble getting the caliper assembly back on. The two flange bolts that secure the sliding caliper pins are pretty east to loosen( only around 20 ft pounds),
the brake slide pins are then easily accessed when you swing the caliper out of the way.
You don' t have to remove the caliper assembly completely if you like. Use a silicone based grease meant for brake lubrication.
As you can see there is tons of brake pad material, next wheel swap in the spring I will take the pads out and make sure they are not glazed or delaminating from the obvious infrequent use.
