Gentle stops only until the fur is worn off the pads, and they are beginning to wear in to the rotor surface. These rotors appear to have distinct tool marks, so the pads will only touch about 50% of the surface to start with.

Several firm stops from about 40 mph in rapid succession will seat the pads, but the real key is very gentle use until the full surface is contacting the rotor to prevent local overheating.

Easy to tell when they are broken in correctly, and the braking effect is effortless and powerfull, unlike when you first put them in and they feel mushy.
