The Variation II coaches Possess a manually used foot pedal that will apply the parking brake, plus the AutoPark system which happens to be linked to the equipment shift lever – – i.e. PARK situation to the change lever.
Concerns: When your actuator is now leaking, or you recognize obviously it has been contaminated with brake fluid, then you will HAVE to take motion to avoid AutoPark failure and possible lockup of the parking brake.
Of The 2 wires visiting the yellow knob swap, a person will Normally have twelve volts on it When the ignition is ON. Another relationship on the change will present voltage according to how the swap is about. You really need to use the one that is incredibly hot whenever the ignition is ON.
Can’t be witnessed in photo over, but The underside from the lever is fastened at pivot to right hand brake shoe
The next pertains to bleeding the actuator – – There is a port on the top, back again end on the actuator for this goal.
AutoPark – – A parking brake method identified on some GM chassis which instantly applies a drum brake to the driveshaft. Once the equipment shift lever is set into PARK, this brake is quickly utilized.
So I figure about ninety dollars full for sections, delivery, and labor – – This works out to about 65 dollars for that repair moreover enough time packing for shipment and functioning into the Article Business. If This is certainly greater than you are able to manage, send whichever operates in your case – – no massive offer.
Get beneath the rig and orient that port within the brake drum to 12 o’clock. Open the port and get it over the adjuster; Then, click the adjuster until you will get just the slightest drag.
When these difficulties very first started demonstrating up in this article at the AutoPark Library (it's possible five several years back), we'd are inclined to principally blame them on improper adjustment in the placement swap, and we attached less worth to the switch/cam assembly lubrication. Together with the passing of time nonetheless, We've arrive at feel that most of the problems are more possible connected to the lubrication in lieu of the adjustment.
Should you have had a leaking actuator and have had us (or somebody else) repair it, there is a pretty large likelihood which the procedure has a bunch of contamination and crud in it.
four. You could possibly eliminate just the leaking cylinder, and acquire it or send it to a professional hydraulic shop for service. Test prices obviously prior to going this route. We’ve heard of one that fees 4 hundred dollars – – way far too much within our view.
Goody Box – – A steel box, Situated underneath the coach within the passenger side body rail – – just aft in the transmission. On chassis concerning mid 1994 and mid 2001, it includes the actuator, the pump and reservoir, the pump motor relay, and the solenoid valve.
2. It truly is remotely doable that the big fusible link (sixty amps or so) that shields the relay and motor, may very more helpful hints well be blown. We’ve under no circumstances found this happen as however, nevertheless it has to be considered. Just one could examination for this really easily, by pulling the connector off of your relay, and checking to the existence of 12 volts on one of many two large  wires in the feminine connector.
This is the look at within the rear with the actuator. That is the AutoPark parking brake drum along with the driveshaft that you simply see over the still left facet of the picture.
