In the subsequent PDF compose-up, We'll do our best to clarify The complete AutoPark brake set up and its Procedure is not some thing you can certainly understand at a glance. They intended this floating idea to maintain the shoes form of self centering inside the drum.
Refill the AutoPark reservoir with refreshing ATF and get it done again. 1 flush need to cleanse most methods, however, if you see a lot of residue from the reservoir, you need to repeat the method until everything appears to be like cleanse.
Prior to deciding to can change the jam nut up against the actuator, you'll need to loosen it from up in opposition to the lengthy hex adjuster nut – – you’ll require a set of wrenches To accomplish this.
four. Check the technique to make certain that the shoes are certainly not dragging while in the “brake launched†issue, and that the AutoPark (PARK situation within the gear change lever) will adequately keep the mentor on an incline.
Shake the valve vigorously in an end to finish movement. The idea will be to free up the rod (#7 in the illustration) so it slides forwards and backwards very easily.
If the AutoPark lite stays ON, and especially In the event the pump will not shut off, locate the RGS and find out if it is oily. Pull the wire connector off with the RGS, and find out if there is oil inside the connector. If there is, you would like Test no further – – it really is lousy.
Leap The 2 Massive wire fed terminals – – your motor should really operate. In the picture above, that could be the crimson and orange wires – – They could be distinctive colors with your procedure however, but they WILL be the more big wires. Watch out to leap ONLY Individuals two terminals – – touching others could bring on measurable injury.
So over time, we’ve kind of continually revised our Mind-set about autopark. What it boils right down to is this:
In the reduced photograph, with no hydraulic force inside the cylinder, the piston/shaft will go the many way to the appropriate. (For purposes of the illustration, ignore the little amount of fluid proven in front of the piston. In actual practice, the piston would “bottom out†If your actuator wasn't mechanically linked to the brake method).
This is actually the inlet port to your entire valve assembly. Once the valve is open (no present utilized), the ATF flows in thru #5 and out thru The underside from the outer valve casing #3.
It ought to be emphasised that in most cases an actuator cylinder seal leak is a thing that begins small and grows. At some time, it Should be dealt with, but It's not at all ordinarily a thing that transpires fast and results in instant highway failure or lockup with the parking brake.
At #3, the foot pedal (In case your coach has 1), is usually adjusted by loosening the lock nut, pulling the clevis pin, and rotating the clevis to possibly tighten or loosen the influence in the foot pedal – – Then, switch the clevis pin and tighten the lock nut. This cable and the foot pedal are isolated from your actuator by the design in the lever technique.
crimp connectors, completes the components listing for the module – – but I'd personally insert a provide of wire ties for set up.
These two illustrations to still left display the “boundaries†of the actuator shaft/piston travel. For functions of this Component of the dialogue
