> Either way, you don't need a license or even much in the way of special tools to replace the brake pads, rotors, calipers, or hoses on any vehicles on the road today. Some cars sold today require connecting of specialised diagnostics tool which will allow to change brake pads. Without this tool your calipers will not open. What this tool does? It just sends some commands through vehicle CAN bus, but those commands are proprietary, so you need to pay them about $10k-$100k a year to have access to commands for their cars and licence to use them in your tool.
