Installing wheel spacers?

[Lars]

Hi all!

First of all, many thanks in advance for any help you might provide!!

I've order some wheel spacers (H&R's, 10 mm for the front wheels and 15 mm for the rear wheels).

I've been doing a lot of research and I'm not afraid of the rear wheels (remove wheel, remove brake drum cover, bang the old studs out, sit the new studs in, reinstall wheel).

But I'm a little afraid of the front wheels! Is it possible that I will have to remove the disc brake thingy? Is it possible to get it out of the way without having to drain brake fluid or any of that potentially unsafe for noobs like me procedures?

Any light you might shed for me on this will be greatly appreciated :)

Oh, almost forgot, I've got a 2011 5 door european hatchback (model XP9F).

Thanks,
Bruno
