There may be a problem with the brake magnets such as being worn till the winding are visible. You will first want to do a visual inspection for any signs of damage or excessive wear.

You can test the brakes by turning the brake controller to its maximum gain and have someone apply the manual override. If you use a circuit tester like part # PTW2993 on one of the wires leading to the magnet you should show current.

You can use a multimeter like part # PT89ZR to test the brake magnets. I have attached a link to a helpful article that explains how to bench test the brake magnets you can check out.
