I finally got the parking brakes on my Dana axle and come to find out the darn parking brake pedal is messed up. I can press the parking brake pedal down but it doesn't stay down, you can hear it clicking as it goes down, but it comes right back up. Is it possible for the ratcheting arm or whatever the pedal is engaging as it's going down to be worn out? Or is there a way to adjust the pedal inside the car? Or do I have to purchase a whole new parking brake pedal assembly?
