Step 1: Tools
Needle Nose Pliers
Remove the wheel.
Step 3: Remove the Pads
Now its time to remove the old pads, grab the tabs on the bottom of the pads with a pair of pliers. Pull down and they should come out.
Step 4: Put the New Pads In...
So put the new pads in exactly as the others had come out, I find it easier to put the pad closest to the frame first, then the next.
The pads stay on with a small spring clip that fixes to a post on the piston of the brake.
Step 5: Spread Em...
You sometimes (most of the time...) need to spread the pads after putting them in. If you do, DO NOT use a screwdriver, it can gouge the pads.
Instead slide a cone wrench in between the pads and you should be ready to roll.
