It's been 2 years since posting last posting . Have not touched or worked on my brakes. During that time I have set my parking brake religiously every time I park my car. Same thing, sometimes brake pedal is ok sometimes not. Then this summer I started backing out of the driveway and aggressively stopping the car. Have noticed the brakes are the best they have ever been. Have come to the conclusion that the rear brake metering value has too much resistance and the rear brake shoes are too hard. To make the adjusters work the shoes have to grab the drums and the above things don't permit that to take place. So be aggressive to make those drums adjust. Setting the parking brake alone will not make them work.
