When you get the tension off with the cable, you could disconnect the cable by unscrewing the lengthy hex nut off of the actuator rod. Now you could disconnect the hydraulic line likely into your back again in the actuator, unbolt The complete actuator assembly and remove it in the mentor.
This is the rather prolonged and complicated document. If you have inquiries or feedback, or if you can get trapped on this challenge and want support, Get in touch with us.
Pull the feminine connector off The sunshine Swap and look for voltage amongst the terminals and floor – – One terminal really should be hot, and a single cold – – You ought to faucet into your cold one particular.
Criteria: In case your actuator is presently leaking, or you already know obviously it has been contaminated with brake fluid, then you will HAVE to just take motion to prevent AutoPark failure and probable lockup of your parking brake.
If you cannot see any evidence of a leaking seal, but your mentor is around ten decades previous or older, you might want to consider seal alternative over a proactive basis, and at your advantage – – like over the Wintertime months or involving visits.
The following writeups and pics have been packaged to deal with the analysis and when important, the substitution of a unsuccessful Rotten Inexperienced Switch – – aka the pump motor swap or RGS. Considering that these memos had been prepared to deliver out independently normally, there may be some duplication in information.
Refill the AutoPark reservoir with clean ATF and get it done once again. One flush should really cleanse most methods, however, if you see loads of residue inside the reservoir, you'll want to repeat the process till every little thing looks clear.
The sooner versions of AutoPark (from ninety four around about mid 1001) possess the pump and a lot of the other goodies under the coach, but the later versions don't.
You will find a cable heading in the brake drum for the lever relay – – as depicted in the following illustration of the lever arm assembly:
The RGS threads into a bit that appears relatively just like a hex pipe reducer. It is actually fabricated from shiny delicate aluminum. 1 aspect of this reducer incorporates a 3/eight – 24 female thread into which the RGS screws. The opposite (male) end screws in the pump physique itself. Quite a few folks have said that they stripped the feminine thread in the whole process of installing the new RGS, and also have Therefore observed it essential to drill out the outdated threads, and re-tap the opening to anything much larger.
These relays do have a tendency to toast – – after some time. Particularly if the technique has taken the punishment most commonly occasioned by failure on the RGS (Rotten Environmentally friendly Swap). In the event the RGS shorts “ON,†the relay may be issue to prolonged intervals of Procedure which happen to be bound to deteriorate the contacts less than weighty current load.
You could begin to see the printed wires, connections etcetera., Should you look at this printed circuit, you’ll see that it has loads of info together with labeling of the different lamps, gauges etcetera.
Clarification: Most of the GM literature claims you don’t dare work on these actuators simply because the spring in them is quite robust, and if you just take them aside factors may brake repair possibly fly throughout hell and injure somebody. Accurate more than enough for those who don’t know what you are doing. BUT, Here's what you are able to do – – You are able to compress that spring and cage it (maintain it compressed) Prior to deciding to take the actuator apart. This is performed by simply turning that #3 nut to the proper, up against the actuator housing, until finally you've got the spring compressed – – by virtue with the nut pulling the shaft into the left.
, will establish the existence, or absence of voltage to electrical power the Keeping coil. If twelve volts is NOT current (exam with ignition ON, don’t start off motor, shift change lever to NEUTRAL, if there is a yellow knob, it needs to be pushed IN), then there is probably a malfunction Someplace within the Handle circuit.
