Fits my 2003 Trailblazer perfectly. All rotors/pads replaced at the same time so it's hard to tell exactly how good these pads are individually. Suffice to say I'm happy with the overall changes and stopping power is good. Replacing pads/rotors is a fairly easy job that can save you some money. don't bring it to the store. You'll need some pretty basic tools, and there are LOTS of step-by-step guides online if you need them. However, brakes are important to your driving behavior and are not dying out. So if you are a beginner, it is best to hire a helper who knows his stuff.
