I switched out the parking brake pads, but brakes still will not hold While in neutral. I turned star adjuster to expand to inner of rotor. It appeared to initially hold. Then it lost tension when I tested it.

Hi and thanks for using injector

Often times, the brake shoes will center themselves when first applied. Anytime I replace drum style brakes, I adjust, apply the brake several times, readjust, and do it until it works properly.

Make sure cables are not broken or stretched. Here are the directions specific to you vehicle. It also includes how adjustment is done. Take a look at them to see if you did everything correctly. All pictures correlate with these directions.
