This photograph should help most coach owners establish numerous elements in their AutoPark parking brake technique.
This illustration reveals how the configuration of your pink lever influences the cable movement. The geometry of the set up is these that If your blue cable moves about an inch, the crimson cable will shift about an inch and 1 / 4. This is important to recollect in any dialogue of actuator journey.
Another factor is to make certain that you use ATF – – and that is what's used in the AutoPark program, NOT hydraulic fluid.
When you launch the brake pedal, a square Slash O-ring rolls the piston again into your bore on the caliper. To compensate for brake pad put on, the caliper slides on hefty steel “pins.” The car makers acquire precautions to forestall these pins from rusting by installing rubber sealing boots.
This doc can be a compilation of a number of different publish-ups. What we’re seeking to do here is consolidate the necessary details needed so that you can make an enough shoe adjustment (or shoe substitute) in your AutoPark parking brake assembly.
Aluminum composition resists corrosion and stops rust from formingAluminum building gives a lightweight option to major Forged iron – creating a lower-inertia drum that stops quicker
If you have had a leaking actuator and also have experienced us (or some other person) repair it, There's a very large chance the technique has a bunch of contamination and crud in it.
Prior to deciding to can switch the jam nut up versus the actuator, you'll need to loosen it from up from the extensive hex adjuster nut – – you’ll need a set of wrenches To achieve this.
The following step will probably be to get rid of all four nuts from their studs. This will permit the cylinder to easily be pulled off of the actuator studs. A different picture – –
The following photograph illustrates the AutoPark parking brake lever relay technique with optional pedal brake which is located only on coaches built amongst about mid ninety four to mid 98.
This depicts an conclusion cap for the valve assembly when essentially there is one thing quite distinct With this situation. The mechanism over this place features the coil, along with a sealed tube which has the slug that is forced downward when current is applied to the coil.

Here's an online resource with the RGS – – aka the pump motor switch. This resource is reported to get a helpful spot for other GM components in addition. The GM component amount is 15961566. It is stamped on the case. You are able to order it online at: , I’m informed that Amazon has the better pricing
Rationalization: All of the GM literature says you don’t dare Focus on these actuators due to the fact the spring in them is extremely solid, and once you just take them aside things might fly all over hell and injure a person. Genuine more than enough when you don’t know what you are carrying out. BUT, Here's what you can do – – You can compress that spring and cage it (preserve it compressed) Prior to deciding to go ahead and take actuator aside. This is certainly carried out simply by turning that #3 nut to the best, up versus the actuator housing, until finally you've got the spring compressed – – by virtue on the nut pulling the shaft to the left.
