Yet another essential element: If you Keep to the cable from the parking brake drum, it doesn't go straight to the actuator. Rather, it can be linked to a mechanical system referred to as “The Lever Relay.
In case you have experienced a leaking actuator and also have had us (or somebody else) repair it, there is a incredibly high likelihood which the method has lots of contamination and crud in it.
On a pretty frequent foundation, I'm asked to elucidate why AutoPark systems even exist. In exactly the same vein, lots of people check with if they are able to change over to an all handbook procedure – – either a foot pedal or hand lever kind, and disconnect the automatic apply (AutoPark) part of the program.
Lever Relay – – A program of levers that mechanically connection the actuator to the parking brake drum. They are connected by cables on the actuator along with the brake drum. Found on the driver facet of the coach, fastened into the remaining hand frame rail – – close to the transmission/engine.
one. If you're able to’t quite get to the change, you could possibly acquire a little paint brush and duct tape it into a stick – – offering the desired excess arrive at. Get the brush liberally smeared up having a sticky grease like LubriPlate.
If for many reason You're not cozy with generating the above tests, or perhaps lack the right applications, a superb different might be to easily recognize the relay, clear away it, and go acquire One more 1.
Rationalization: Every one of the GM literature states you don’t dare Focus on these actuators Try These Out because the spring in them is extremely potent, and when you consider them apart matters may fly throughout hell and injure somebody. Correct sufficient in the event you don’t know what you're executing. BUT, here is what you can do – – You can compress that spring and cage it (maintain it compressed) BEFORE you take the actuator aside. This is done by just turning that #3 nut to the best, up in opposition to the actuator housing, till you might have the spring compressed – – by virtue in the nut pulling the shaft towards the left.
be almost fantastic. Any extra slack plus the brake will never maintain firmly, and excessive stress will likely have the shoes dragging. Although this kind of system can tolerate almost no don or cable stretching with no want for adjustment, it have to be remembered that this is a static brake – – not a dynamic brake.
Can’t be found in photo previously mentioned, but The underside from the lever is fixed at pivot to appropriate hand brake shoe
That is a minor button valve. It is captured in position but can “float” during the up and down course. It rather definitely can avert circulation backwards up into the valve bodies, but precisely what that accomplishes, I've still to figure out. It opens specifically into your exit line going to the reservoir, which is never under pressure other than atmospheric.
Goody Box – – A metal box, Positioned underneath the mentor over the passenger facet body rail – – just aft of your transmission. On chassis concerning mid 1994 and mid 2001, it incorporates the actuator, the pump and reservoir, the pump motor relay, along with the solenoid valve.
On all versions of AutoPark, there is a drum brake on the driveline – – ideal at the rear of the tranny. Altering it really is very like carrying out the brakes on an more mature passenger car or truck.
It is sort of difficult to forecast which coaches will experience this unique failure, but we are fairly persuaded that most often, the perpetrator is simply plain AGE and in some cases HEAT.
We've been hoping that the availability of the package will serve to advertise the installation of a Genie Lamp on each and every coach that is supplied Along with the J71 AutoPark program.
