the conventional shut-off stage, along with the motor is just stalling underneath the too much load. If the motor stalls, The present placed on it is significantly improved – – This extraordinarily large current will bring about substantial temperatures in the motor, which subsequently will excursion the thermal overload security change that is certainly developed into the motor. The motor will cease looking to run so long as the thermal change is tripped – – BUT, following a few minutes or so, the motor will interesting adequately to enable the thermal protector to RESET.
Around journey – – A problem characterised by owning the actuator piston going farther than it's designed to in standard operation.
Yet another vital detail: In case you follow the cable within the parking brake drum, it does NOT go straight to the actuator. As an alternative, it can be connected to a mechanical device known as “The Lever Relay.
So Exactly what are we to conclude from All of this? Basically, Now we have a binary reporting method that provides us only a little amount of the accessible facts.
Get underneath the rig and orient that port on the brake drum to twelve o’clock. Open up the port and acquire it more than the adjuster; Then, click on the adjuster until finally you receive just the slightest drag.
As a choice, we could supply you having an adapter that we make within our small AutoPark equipment shop. We make them of 12L14 cost-free machining metal, and they have threads which might be significantly not as likely site to strip.
If you see this reservoir, You then definitely have the later on version which operates off of its individual electrical pump.
We now have our quite personal actuator with which we will do assessments and make measurements. Further information and facts is predicated on what we could carry within the manuals We've, and what we have extracted from our background and encounter with AutoPark parking brake programs – – a few ten yr journey.
As pointed out earlier mentioned, Many of these methods also have a guide means of applying this brake – – in addition to the AutoPark. From about mid 98 on nevertheless, the one parking brake purpose is supplied by the AutoPark – – No foot pedal or lever.
Also, the (!) light-weight stays on and also the buzzer nonetheless Appears once the Yellow Button is pushed in, but they ought to go off Based on Workhorse. Workhorse states that this means that the brake process desires servicing. But if I place the shifter in Generate Using the Yellow Button pushed in, both equally the “AUTO PARK” Show as well as the (!) gentle and also the buzzer go off. What’s occurring? What demands servicing?”
If your actuator is on a method that is definitely ten several years old or maybe more, then you might want to consider some preventative action.
two. The RGS has absent undesirable and has turned around the pump As well as the AutoPark mild. Tension will go thru the roof and Soon rupture the RGS or Various other element. Then, the brake will immediately utilize.
four. Take a look at the procedure to be sure that the footwear will not be dragging inside the “brake released” problem, and that the AutoPark (PARK posture within the gear shift lever) will adequately keep the coach on an incline.
Removing with the previous seal necessitates some Unique notice. It truly is very easy to mar the floor on the piston in this method. We often encounter pistons that have been ruined (by improper procedure) to the extent we need to chuck them up inside the lathe and clear up the buggered surfaces.
