The whole reason it was called Repack was because they repacked the hubs with grease after cooking it all out on a run. A roller brake possibly would be a little less heated but I don't know by how much if any. The shop I started wrenching at we rarely saw roller brakes and didn't sell anything with them and now I am at a higher volume shop but I am doing less wrenching except on special projects and oddball stuff but we are generally using discs or rim brakes so I just never get a chance to work on them and am so busy with other stuff I wouldn't have the chance if I wanted.
