Well, that is explained in the TSRM:

Off the top of my head...
First crack the lugs loose
Jack the car
Take the wheel off
For the front--remove the brake hose from where it is mounted (I think it is a 10mm?)
Unbolt the the lower part of the caliper from the bracket
Lift the caliper up and then slide if off
Remove brake pads
Apply Brake Quiet to the backside of the pads, NOT the friction side (this keeps them from squeeling)
Insert pads
The rest is the reverse of taking them off.
At least that is one version from memory...
