Hello, I just bought a 2010 XC90 and this is my first post on the forum. I am replacing the front brake pads and rotors and noted the caliper set-up is much different than other cars.

Is grease required on the caliper slides or is this a dry system? I didn't see any grease on the caliper slides when I removed them but then these are the original brakes with 100,000 km.
