It's important to recognize that the parking brake drum process on an AutoPark parking brake Outfitted chassis is created like a STATIC Procedure.
Since brake pads are just one achievable difficulty with a brake program, there are other products to examine also. If your pads are worn slender or are cracked from heat all through use, pad replacement may very well be vital and also the method must be inspected.
AutoPark – – A parking brake process uncovered on some GM chassis which automatically applies a drum brake to the driveshaft. If the gear shift lever is place into PARK, this brake is mechanically used.
four. Examination the procedure to make sure that the shoes are usually not dragging during the “brake introduced†affliction, and that the AutoPark (PARK place within the gear shift lever) will adequately hold the mentor on an incline.
Refill the AutoPark reservoir with clean ATF and get it done again. One flush really should cleanse most systems, however, if the thing is a great deal of residue during the reservoir, you must repeat the process until every little thing seems to be thoroughly clean.
At last and (we think) extremely importantly, we have a complete J71 Autopark system that has been converted to your benchtop take a look at station. It's been modified that has a tension gauge and changes within the valving and wiring which empower us to work with it for arduous testing of the repaired cylinders.
The following illustrates and points out just about all attainable Genie Lamp status eventualities that might be shown on any presented set up. This writeup will give you (all on one sheet) a fairly detailed notion of what all the assorted Genie Light-weight circumstances could indicate.
Here's an online resource for the RGS – – aka the pump motor switch. This supply is claimed to become a handy place for other GM elements in addition. The GM component quantity is 15961566. It is stamped on the situation. You may purchase it online at: , I’m advised that Amazon has the better pricing
Issue C – – Your AutoPark pump is jogging or endeavoring to operate. The method senses that the tension is under 500 psi. Ordinary going in the future pressures need to be around 1600 psi – -This is the Negative CONDITION. If lockup has not presently transpired, it is probably going to occur at any instant.
About the Edition III programs (2001 and afterwards), the relay is often over a pigtail hanging down below the pump assembly, but at times it's mounted simply to the proper of the pump motor. The pump on these newer techniques is situated up inside the front with the mentor, beneath the utility hood.
An additional important depth: If you Keep to the cable from the parking brake drum, it does NOT go straight to the actuator. Alternatively, it is connected to a mechanical unit termed “The Lever Relay.
Explanation: Each of the GM literature claims you don’t dare Focus on these actuators since the spring in them is extremely solid, and any time you take them apart factors may perhaps fly around hell and injure an individual. True sufficient in case you don’t know what you're accomplishing. BUT, here is what you are able to do – – You are able to compress that spring and cage it (keep it compressed) Before you decide to go ahead and take actuator apart. This can be accomplished simply by turning that #3 nut to the proper, up from the actuator housing, right up until you have got the spring compressed – – by advantage in the nut pulling the shaft on the still left.
The former illustration reveals the various mixtures your Genie Lamps may well display. Some are regular, some are more of a website dilemma, and a few are really serious adequate to call for speedy attention.
Actuator – – Located on all AutoPark units. A hydraulic cylinder that is intensely spring loaded. The spring applies the parking brake, and also the hydraulic cylinder when pressurized, releases the parking brake.
