The above info pertains on the J71 AutoPark method utilized on coaches built from about mid 94 and later. When you've got one of the sooner programs that operates off of the ability steering program, allow me to know. That is certainly a very distinctive actuator. Additional harmful to work on.
Have got a foot pedal to the park brake, just checking the AutoPark will be the only thing vital. If the AutoPark is Performing perfectly, nevertheless the foot pedal isn't, you may have to adjust the cable to the foot pedal.
On the subsequent will be the block diagram to the Edition III AutoPark system. Once again, the Genie Lamps are inserted in the circuit, and We'll give a lot more particular info on where by the actual connections are to get produced later on In this particular doc.
IMPORTANT Take note: This legend goes that has a modified drawing in the parking brake drum and related areas. The initial drawing lifted with the handbook, mistakenly demonstrates the sections inverted – – With all the star wheel adjuster at the BOTTOM in the backing plate in lieu of at the best where it is definitely located. This new legend plus the modified drawing mirror what you ought to find out if you're taking apart the parking brake assembly.
On all variations of AutoPark, there is usually a drum brake over the driveline – – appropriate behind the tranny. Adjusting it is much like accomplishing the brakes on an more mature passenger motor vehicle.
Goody Box – – A metal box, located underneath the mentor about the passenger aspect body rail – – just aft of the transmission. On chassis involving mid 1994 and mid 2001, it contains the actuator, the pump and reservoir, the pump motor relay, as well as solenoid valve.
So – – Bottom line: We suggest people to master about their AutoPark. Nearly nearly anything that goes Mistaken with it, is one thing you could take care of by yourself For anyone who is Alright with a few straightforward mechanical work.
four. Check the process to make sure that the sneakers usually are not dragging during the “brake launched†condition, and which the AutoPark (PARK placement around the gear change lever) will adequately maintain the coach on an incline.
It should be emphasized that normally an actuator cylinder seal leak is something that commences tiny and grows. At some point, it Needs to be handled, but it is not ordinarily something which takes place rapidly and triggers speedy highway failure or lockup in the parking brake.
 If you will find previously indications of leakage, Then you really will certainly want to deal with this on much more of a priority foundation. Unless of course It's a massive leak where you see the reservoir acquiring low, you continue to possibly have some wiggle room on how quickly the repair demands completed.
Hook Browse Around THIS Web-Site your superior force hose back again up into the again from the actuator, refill the reservoir all over again, and you should be good to go.
Repairing The situation: As mentioned above, we’ve started to feel that the lubrication may very well be additional significant when compared to the adjustment. Considering that the lubrication procedure calls for no disassembly it's the much a lot easier job of The 2.
Most actuators Possess a factory placard of some sort on them, which factors out the Threat (perhaps sizeable) of opening up spring loaded actuators. It can be VERY risky and should not be undertaken devoid of some Doing the job knowledge of these equipment.
To comprehend The full concept behind the Genie Lamps, we must initial study the AutoPark idiot lamp set up that includes the GM AutoPark Geared up chassis. The explanation is as follows:
