I forget what I paid for them.I have a ongoing tab at the bike shop,with tires,oil,filters,you name it. So I just put $ in the kitty whenever I have it.But I put in the HH pads and it made a big difference. Its pretty simple, just when you take the old pads off,clean/degreese evrything and put the new pads in the same way.Once I get the new pads in and open them up, I put a small wood wedge or plastic hose inbetween so they slip on the rotars instead of goudging them up with a srew driver.
