A brake disk or drum has at least one working surface which opposes a braking member such as a brake pad or shoe. A plurality of spaced, raised island formations are provided across the working surface, with channels extending between the island formations. Each raised island formation has an outer surface which contacts a brake pad or brake shoe during braking.

A brake rotor has a circumferential brake track disposed about an axis of rotation of the brake rotor. The rotor has an outer peripheral edge circumferentially around the brake rotor. The rotor has two surfaces that face axially outward away from one another and that are on axially opposed sides of the brake rotor. The two surfaces define a thickness therebetween. The rotor has an edge surface facing radially outward on the outer peripheral edge. The rotor has a transition between each of the two surfaces and the edge surface. At least a portion of the edge surface is not perpendicular to the two surfaces in an axial direction.

Land vehicles and methods of operating land vehicles are disclosed. A land vehicle includes a frame structure, a plurality of wheels, and a brake system. The frame structure includes a front cage that at least partially defines an operator cabin and a rear compartment positioned rearward of the front cage in a longitudinal direction. The plurality of wheels are supported by the frame structure. Each of plurality of wheels is sized to permit direct integration of an electric motor therein.

A pad pin receiver includes a body plate is attached to an inner side of a pin insertion portion provided in a back plate of a disc brake pad. The pin insertion portion engages with a pin inserted into the pin insertion portion during braking. The body plate covers a portion of an inner peripheral surface of the pin insertion portion. A bent plate is bent at at least one end portion of the body plate in a length direction of the body plate. When the body plate is attached to the pin insertion portion, the body plate extends in a thickness direction of the back plate, and the bent plate overlaps with the back plate in the thickness direction of the back plate.
