There are plenty of How-to's on this forum, simply use the search function, and filter by "brake install" or "Rotex Gold" or etc., you get the idea; Search and you shall find!

If your just changing the pads, I'm not sure where you got $100 price tag, a full set of Rotex Golds for the front end only cost $55 from brakeworld and I'm sure buybrakes has them for about the same price (if not cheaper).

As for bleeding the brakes, if your just replacing the pads you will not need to bleed the brakes (assuming you do not remove the brake line from the caliper assembly). Tip: If your just changing the pads, put a plastic water bucket between the rotor assembly and the inner wheel well, so you can rest the caliper assembly on it while you are prepping the pads with anti-squeal grease and fitting your inner pads.

I'm not a mechanical genius, but it took me longer to clean the inside of my wheels than it took me to change the pads, and if it wasn't for that freaking outside pad spring from hell, it would have taken me less time than that!

Again, you should really search the forums for information on this topic, you will get excellent information and some additional tips that will definitely help you on this quest!

Good Luck!
