    Default 2007 nbs sierra parking brake issue

    Wife's brother used truck the other day and pushed emergency brake pedal so hard it went completely to floor. All cable are alright. Took drums off and cables still locked into springs. I watches parking brake pedal as I pushed it to floor with hand and its not pulling on cable anymore. The black plastic piece that cable is locked into doesn't move. The pedal goes down and the cam comes around and nothing. Is the pedal assembly broke? Can someone please take a short video with their phone of the pedal assembly as they push the pedal by hand? I'd like to see what all is supposed to be moving and going on when pedal is depressed. Send me a pm and ill send you cell number you can send video to or email. However you want to do it.

    The nbs has a self-adjusting pedal mechanism. I don't know much about them -- mine has always worked ok.
