Hi Guys,
I'm meant to be getting my rear discs and pads changed, my friend is going to be changing them for me but is being abit hesitant

as he says that the discs are really rusty and may need to be forced off and may break some parts inside, what I need to know is what other parts I may need to purchase just in case something does break? (I have already purchased the pads and discs)
Cheers
