@ Anon4155- If you search youtube you will be able to find a number of instructional videos on changing brake pads. The procedure is simple, varying only slightly from vehicle to vehicle.
I have done brake work on numerous vehicles and my best advice is to:
1) Borrow a Hanes or Chilton's repair manual from your local library
2) Read the instructions
3) Then watch the video before doing brakes for the first time.
Make sure you have all of the parts, tools, and time you will need to complete the job.
If you run into trouble, the person at your local auto parts shop can usually give you advice on whatever has you stuck. Good luck, and have fun learning how to do a job a shop would charge you hundreds for at a fraction of the cost.
