Take away the relay within the socket/connector. Find the two terminals during the connector that happen to be fed by the two Big wires.
This details sheet is new, and is composed to handle an AutoPark parking brake issue that is now pretty prevalent in only the previous couple of months.
DRAG – Sticking brakes, incredibly hot wheels or engine which appears to have misplaced electric power. Automobile brakes could possibly be failing to release; the affliction can reverse itself, leaving you without having brakes in the slightest degree. This might suggest brakes service is needed.
The following action is going to be to eliminate all four nuts from their studs. This enables the cylinder to easily be pulled off on the actuator studs. Another photo – –
In general, we inspire mentor owners to try and do pretty much any of the treatments that it will take to maintain their AutoPark system up and functioning appropriately. The exception to This is actually the seal substitution during the hydraulic cylinder for your actuator. There isn't any issue that some entrepreneurs might have the machines and ability to do this task, but in many circumstances this is probably not the case.
Whenever you get The stress off of your cable, you can disconnect the cable by unscrewing the prolonged hex nut off of your actuator rod. Now you'll be able to disconnect the hydraulic line likely into your back of the actuator, unbolt The complete actuator assembly and remove it in the mentor.
Much of the data we provide is supplemented with images and diagrams. A telephone conversation definitely lacks these rewards.
The pump will continue to be off till the stress has dropped to 1200 psi or reduce, and then it will cycle as well as the stress operates back up to 1600 psi. This hi strain is required to RELEASE the parking brake Therefore the mentor can roll.
Hook your higher tension hose back again up for the back again on the actuator, refill the reservoir yet again, and you should be very good to go.
A lot of the subsequent is stuff We've lifted from manuals and such – – There will very probable be some duplications of content between the assorted create-ups.
Together with the ignition ON (don’t get started engine) and change lever in REVERSE, – – both equally yes of These strain switch (the gray Lite Switch and also the eco-friendly or brown pump motor swap [RGS RBS] ) connectors will likely have one particular in their two terminals with 12 volts current. Nonetheless, you want the terminal that is definitely switched – – not the one that is hot all the time.
So – – Assuming the cables on their own are in good problem, this leaves our remaining variable to generally be the extended hex nut within the actuator shaft – – depicted as #1 in the illustration above. It is vital to notice that this actuator is demonstrated within the BRAKE ON problem – – Check out TO VISUALIZE IT Together with the SPRING COMPRESSED during the BRAKE OFF issue. Together with the brake OFF as well as the actuator shaft prolonged to its mechanical limit, we might want to regulate the extended hex nut just to The purpose where by there was no slack inside the cable program – – no far more, no much less. If we then remove the hydraulic force from the actuator, the spring will develop, along with the piston and shaft will go to the proper – – implementing the brake. Therefore the brake lever while in the drum will go about an inch, the cable going to the lever relay will go regarding the very same inch, the cable likely FROM the relay to the actuator will move about one.
Currently we’ve noticed a massive increase in the reviews of J71 Automobile Park braking brake techniques with leaking actuator cylinders. For years, this malfunction is Pretty much unheard of, but in the last six months They are really popping up with disturbing regularity.
Form III program – – Discovered on chassis built involving (approx) mid 1998 and 2007. Much like Style II but lacks the manual foot pedal for software in the parking brake. Has a yellow press-pull knob around the dashboard.
