Are our brakes axial or radial pump?

I don't see how that caliper mounting is much different than our caliper mounting. Both from behind at a slight angle. What am I missing?

The bolts attaching the radial caliper are parallel to the direction of the rotation of the wheel (they bolt down through the very top and bottom of the caliper with the bolts pointing straight toward the fork tube), whereas as on ours they are at 90 degrees to the direction of rotation (the bolts face toward the tire).

When you hit the brakes hard the callipers grip the calipers and are immediately pushed upward (opposite rotation). At the same time they deflect a few thousanths of an inch to the left and right. Radial mounting significantly reduces this, giving you much better feel and preedictable/consistent braking.

They don't serve a huge purpose on street bikes, unless you really are a track rat. They were one of those products born from racing that probably served as more of a marketing tool to shore up companies' "from the racetrack to the road" street credit (like carbon ceramic brakes on sports cars). Now everything with sporting pretentions has them, as anything less is falsely perceived as sub-par.
