| | IRD Dual Banger Mechanical Disc Brakes |
 | | When you pull the brake lever, a cam moves both the outboard pad to the right and the inboard half of the caliper body (which houses the inboard brake pad) to the left—in effect, squeezing the rotor simultaneously from both sides. |
 | | IRD calls this model the “Dual Banger” because the brake does, in fact, sandwich the rotor, but the way it accomplishes this is very different from what you may have encountered with hydraulic, dual- piston brakes. |
 | | Since the brake pads wear quickly, the next logical question is “Can you actually find replacement pads for these things?” The good news is that the Dual Bangers use the same pads as Shimano’s Deore Mechanical discs, so replacements are readily available. |
