I have not changed brake pipes since 1980,I suspect it has not changed much,you need the special tools,copper is fine to use,and you need to be able to raise the car /van up on axle stands or a lift,the steel ones fitted to motors,do rust but many times a MOT fail is nothing more than surface rust which can be rubbed off and coated ,best of luck with it,I know I took all weekend when I did it,make sure you have everything you need before starting it,unlike me.
