EASY
it's a rather easy job.... shouldn't be more than 20 minutes for each side... just did mine a couple days ago...
on a flat surface, make sure your E-Brake is on, make CERTAIN your SPYD3R is stable once up in the air (do 1 side @ a time 2 b safe)... remove 1 wheel and take a picture of your Caliper prior to dismantling (or use mine, below), make sure you open the cap of the Master Cylinder, put a rag under the Master to catch any fluid that may drip out... remove 2 15mm bolts holding Caliper, with an old coat hanger, make a hook to hold Caliper from pulling on the brake line... remove small Clip from Cross-Bolt, put clip in a container - otherwise, these little things grow wings and fly off, never to be seen again... un-srcew Cross-Bolt, remove Clip, remove Pads, press 4 Pistons back into the Caliper (no tools required here, hand pressure is all you'll need).... clean the Caliper, insert new PADS, install Clip, insert Cross-Bolt and screw it back in, put the Fly-a-Way Clip back onto the Cross-Bolt, align Caliper with mounting holes and Rotor... re-insert 2 15mm bolts, tighten and re-install the wheel... repeat on opposite side... return to the Master Cylinder and check the fluid level, add if required... re-install the cap, making sure it's tight... mount your SPYD3R and depress the brake pedal until it's firm... clean up the surrounding area, and go for a short/
slow ride, pressing the brake pedal as you go... you should know if your efforts are successful within 100 ft... re-check Brake Fluid upon your return... you should check Brake Fluids periodically afterwards...
hope this helps... good luck and enjoy your ride...
