'93 P30 - Adjust Parking Brake (Autopark drum)

thesameguy · Dec 29, 2014

Can anyone point me to a specification for adjusting the parking brake? Most of what I've seen is limited to "disconnect the driveshaft and spin the drum," but that seems like a fairly inaccurate procedure for such a thing.

Much thanks!

The acknowledged expert on that system is a chap that goes by the name of "OldUsedBear" . His documentation can likely be found here: www.oemys-performance.com/j71autopark.htm

Indeed! Very familiar with the site and it coached me through understanding the system and ensuring it works properly. Unfortunately it focuses on the hydraulics and not the mechanicals... I'm really not looking for autopark information per se, but rather the spec on adjusting the drum itself. I'm sure the info exists in some official GM documentation somewhere, I've just been unable to find it.

Wow - that is AWESOME, thanks! How did you find it? I spent over an hour Googling pretty intensely yesterday and got nowhere. Grrr!

Glad to be of service.

I googled The following " GM autobrake adjustment procedure "

There are a few additional entries that you may wish to pursue. Good luck.
