Criteria: If the actuator is currently leaking, or you are aware of for sure it has been contaminated with brake fluid, then you'll need to acquire motion to stay away from AutoPark failure and doable lockup from the parking brake.
The above information and facts pertains into the J71 AutoPark method applied on coaches designed from about mid ninety four and later. For those who have one of the earlier methods that operates off of the facility steering technique, allow me to know. Which is a completely distinct actuator. A lot more perilous to operate on.
The first thing we'd like to deal with is to understand which Edition of AutoPark parking brake you've got. It's because ninety four has become the transition many years. Mainly, the earlier kinds possess the AutoPark running off of the ability steering, even so the later on types have their own devoted pump and reservoir.
The Edition II coaches have a manually used foot pedal that will use the parking brake, and also the AutoPark program that's connected to the equipment shift lever – – i.e. PARK situation over the shift lever.
nomination as one of many quintessential idiot lights of all occasions. Let us to explain our harsh judgement:
This illustration shows how the configuration of the pink lever influences the cable movement. The geometry of this setup is this kind of that In the event the blue cable moves about an inch, the pink cable will move about an inch and 1 / 4. This is essential to recall in almost any discussion of actuator travel.
Poppet Valve – – Why not look here A A technique valve which is situated in the fitting slightly below the RGS. It is easily and often shed when eradicating the hex retainer that retains it in place.
I've tried to tighten the 6 nuts about the unit and have carried out 4 but can’t work out how to get to your remaining two but I guess that will not enable if the O ring is leaking. Any support will likely be greatly appreciated. Ed by means of electronic mailâ€
Actuator – – Discovered on all AutoPark units. A hydraulic cylinder that is greatly spring loaded. The spring applies the parking brake, and the hydraulic cylinder when pressurized, releases the parking brake.
We have found a a lot better procedure for “tapping into†an current wire. In place of utilizing the folding “matchbook†variety of connectors which you squeeze on with a set of pliers, we now (enthusiastically) advocate the newer “drive-in†style of connector.
As mentioned earlier, This is often one of the most wearisome procedures one particular will come across in AutoPark repair. It can be under no circumstances abnormal to own to repeat some of the bleeds over once.
Sounds – Brakes ordinarily make some slight noise when utilized, but generally create squeal or grinding noises which are quite loud.
We’ve created a individual details sheet on the various repair options as we see them. If that is a subject of interest to you, we are going to be glad to share supplemental details. You will find DIY associated solutions that may preserve you some huge cash.
The trouble: For various decades, we are already hearing about a challenge that will involve shifting from PARK to REVERSE – – In the event the change lever is moved outside of PARK, the AutoPark procedure is supposed to launch the parking brake, and allow the coach to roll. Even so, it seems the switching mechanism which makes this doable (generally known as the “the equipment shift lever place swapâ€), does not always precisely feeling the change lever situation.
