simple task really. i had an 04 dc for a while. you will see two pins that run through the outboard edge of the pads. remove the clip on the end of each pin. pull pad out of the caliper. note the position of the shim when you remove, as it can go two ways. you will have to compress the caliper piston if your old pads are excessivly worn. you can go buy a tool for that, or use a c-clamp as i do. reinstall new pads.
hope this helps. the 04 has the most straight forward system on the discs that i have ever seen. good luck
