Cub Cadet lawn tractors have been around since the early 1960s. The Series 1000 Cub Cadets are the company's smallest and least expensive offerings. The Series 1000 features a tight turning radius for ease of maneuvering around obstacles, Kohler gasoline engines and cutting decks ranging in size from 42 to 54 inches. The Series 1000 Cub Cadet also features a rear disc brake that must be adjusted from time to time to restore braking performance.
Drive the rear wheels of the tractor onto blocks of wood to create working room underneath. Chock the front wheels to prevent movement.
Locate the disc brake on the underside of the rear of the tractor just inboard of the right rear wheel.
Locate the cotter pin---which keeps the crown nut from turning---on the right side of the brake assembly. Pull the pin out with a pair of pliers and discard it.
Insert a feeler gauge into the gap between the brake disc and the brake pad. Tighten the crown nut with a wrench in a clockwise direction until the gap is 0.011 inch as measured by the gauge.
Push a replacement cotter pin into the hole in the crown nut. Bend over the ends of the pin with a pair of pliers to keep it from sliding out.
Remove the wheel chocks and drive slowly off the blocks of wood.
