Main brake and parking brake should be engaged and released

without great resistance and severity.

Check cylinder movement and correct return of piston to start position.

The help of a second person is required, who shall engage trailer

brake.

Check if axle elements are in place, (cotter pins in castellated nuts, expansion

rings etc.).

Check hydraulic cylinders or pneumatic cylinders for tightness - compare
