As many have stated, the pulling of the main fuse is so that the alarm siren (which has its own battery) won't go off when you disconnect power....
If you didn't/don't have an alarm or have an alarm without the optional siren, like on older bikes, there is no need to pull the main fuse...
IMHO....with the close quarters around the battery terminals and the frame on most Harley models, disconnecting the negative cable first, and then reconnecting it last is very important...

Making life hard?
Pull the fuse is obviously real hard! Always disconnect the neg terminal, this is hard. As for the brake pads well i believe my calipers which have ABS the cable maybe has some electric involvement? Every thing i have read says to be careful with this cable. Disconnecting electrics is just common sense!
