A motorcycle brake and suspension system comprising: an outer tube, having an upper end and a lower end, a mainspring mounted inside the outer tube, a brake line traveling through the central axis of the outer tube and looped to allow slack, and a braking system actuated by the brake line. The brake line actuates an integrated padlock caliper disk brake, and is protected by a flexible plastic cover. A fender bracket is mounted on the brake caliper. The integrated padlock caliper disk brake system has integrally formed brake fluid passages in the fork leg, which are hydraulically operative inside the load bearing portion of the fork leg. An adjustable push rod supports the mainspring by adjusting its neutral position length.
