Brake pad and rotor replacement on H1

[drdonpalmer]

Hello, I'm a new H1 owner and new to the board.
Need to do some brake service and the dealer told me there is a special proprietary tool that I can't get that is needed to service the brakes.
The service manual indicates two tools: one is listed as a "crowfoot" used to remove caliper from adapter (this is the front brakes) and the other is part J-42553, which is used to rotate and compress the caliper simultaneously.
What is a crowfoot? Is the caliper compressing tool really necessary? Any tips or known issues when changing out these components? I've done brakes on all my other regular vehicles for years.
Thanks,
Dr. Don Palmer
PS I want to do them at least once for experience incase I have trouble in the field.
