Compensating the rear wheel brakes on the 1922 models is rather complicated, but can be performed in the following manner. First remove the split pin from the hub nut, from the wheel that is locking on first, and then the nut itself. Slacken the brakes right off, remove the rear hubs, and remove the "pull off" springs, and then the brake levers onto the brake camshafts should then be removed. The camshaft actually operates the shoes, forcing them apart when the brake is applied. The brake levers should then be removed and great care should be taken not to loose their keys, which are in the camshaft.

Four wheel mechanical brakes were fitted from September 1923, and a balance gear is located across the frame, behind the gearbox to ensure that the braking effort is distributed evenly between all four wheels. Taking up wear is very simple, and can be made by one adjustment to the rear of the lower end of the brake pedal.
