I have these brakes on my Tallboy;
The brakes came with these pads:
At first I thought I bought the wrong pads, but these work just as well as the stock ones as far as I can tell and they are cheaper. Once you pull your old ones out, be sure to apply enough pressure to the caliper mechanisms to make them flush inside the caliper, otherwise you have to reinstall the pads. Keep your hardware (the locking pin) from your old pads as you may need them to install your new pads.
