<< For safety's sake, do not rely on the spare tire jack to hold up the car. Most are quite weak and very unstable. Invest in some decent jack stands.
Capn is right about the procedure, but he refers to the "master cylinder," when he means "wheel cylinder/caliper assembly."
Get the book at the auto parts store to be sure.
As for tools, Craftsman is totally decent if you're starting out. A complete set of metric wrenches should be about $20-25, or you can buy only the size(s) you need for a few bucks each. >>
yes, don't remove your master cylinder to change your brake pads!
