The subsequent photo illustrates the AutoPark parking brake lever relay system with optional pedal brake which can be uncovered only on coaches created involving about mid 94 to mid 98.
Considerations: In case your actuator is currently leaking, or you already know for sure it has been contaminated with brake fluid, then you will need to just take motion to prevent AutoPark parking brake process failure and doable lockup in the parking brake.
The above mentioned crude drawing is undoubtedly an aid in locating and modifying the star wheel. I’m confident you'll discover it on the 12 oclock place in the backing plate. Once more, this means you will have to rotate the drum these types of which the star wheel port which can be during the rotating drum – – NOT the backing plate,
It is sort of difficult to forecast which coaches will knowledge this individual failure, but we've been quite persuaded that generally, the offender is simply basic AGE and in some instances HEAT.
Considering that this complete system just isn't RIGIDLY fixed towards the backing plate, it sort of “floats†and is self centering – – So equal force is placed on both of those the still left hand and the correct hand shoes.
These relays do often toast – – as time passes. Particularly if the program has taken the punishment most commonly occasioned by failure of the RGS (Rotten Green Swap). Once the RGS shorts “ON,†the relay can be issue to very long durations of operation that are bound to deteriorate the contacts beneath hefty recent load.
All the GM/Chev/Workhorse J71 AutoPark programs, together with the before models that operate off of the power steering, use what might be called a “Brief Toss†method. The obvious way to explain this is likely to be to check it to an everyday wheel drum brake to the family members motor vehicle.
The Edition II coaches Use a manually applied foot pedal that may implement the parking brake, in addition to the AutoPark system which can be connected to the gear shift lever – – i.e. PARK placement on the shift lever.

Others have claimed they could reach the change by stretching.
So Regardless of The point that it is a marginal unit, you have to have one particular and it should be Doing the job (Except you have a Genie Lamp module – – far more on that afterwards). If you want additional information on how the AutoPark Light-weight functions, ask us for our information sheet on IDIOT LIGHTS.
In case the thorough lube position would not heal the shifting difficulty, allow me to know and we’ll go thru the adjustment method.
Failure with the RGS accounts for a large the vast majority of AutoPark technique malfunctions. This unique writeup is intended to handle the troubleshooting and substitute of that switch.
Spring throughout adjuster and two springs at The underside are what retract the shoes when brake is introduced. Additionally they continue to keep some rigidity over the cable if the brake is released.
It's going to be on the driving force’s aspect, to the right of your radiator. A Additional Info few of the “house†builders regulate to hide it behind wiring and various things – – but it's there. If you can’t conveniently locate the relay, simply observe backwards the hefty wire visiting the motor.
