1. An axle assembly comprising:
a wheel hub;
a wheel rim mounted to the wheel hub;
a brake rotor mounted to the wheel hub;
an axle; and
a disc brake that includes:
a first friction element and a second friction element;
a brake caliper including a housing and a bridge;
the housing containing a wear adjustment mechanism and an actuator mechanism having a friction element contacting actuator output to drive the first friction element in a first axial direction; and
the bridge extending over the brake rotor in use and defining a support face to the second friction element in at least the first axial direction;
wherein the first friction element and second friction element each have an effective contact area to the brake rotor of at least 10,000 mm2 and wherein a maximum spacing between the actuator output and the support face is in a range of 75 mm to 50 mm; and
wherein the wheel hub has either a first wheel hub configuration or a second wheel hub configuration that differs from the first wheel hub configuration and the wheel rim has either a first rim configuration or a second rim configuration that differs from the first rim configuration, wherein the first rim configuration is mountable on the first wheel hub configuration but not the second wheel hub configuration and the second rim configuration is mountable on the second wheel hub configuration but not the first wheel hub configuration, and the disc brake does not foul on the wheel hub or wheel rim when the first friction element and the second friction element are unworn and the brake rotor is unworn.
