Recently we’ve witnessed a large boost in the reports of J71 AutoPark leaking actuator cylinders. For years, this malfunction has been Virtually unheard of, but in the last 6 or eight months They're showing up with disturbing regularity.
So – – if you take a look at an image of the actuator shaft Using the brake utilized, the level of space you see amongst the jam nut and also the actuator bracket encounter DOES DEPEND on the star wheel adjustment, As well as ailment of your brake shoes.

some position in this process there will not be more than enough ATF to maintain the parking brake released, and it will implement the parking brake – – Regardless of where you are (rapid lane, driveway and so on.)
25 inches, and also the actuator shaft will move in to the actuator (to the proper as considered in the picture), about 1.25 inches. For the reason that Whole travel of the disconnected actuator is about 2.0 inches, Consequently we should have a “preload” to the huge spring of about .75 inches. In other words, if 1 were to cut the cable beneath the BRAKE ON problem, the actuator shaft would snap again in to the actuator an additional .75 inches. It Is that this preload that makes it somewhat tricky and perilous to disconnect the cable in the lever relay clevis even though the cable is less than this preload rigidity.

Although we’re certain that age is the principal perpetrator, we also know there are several situations the place brake fluid as opposed to ATF has actually been place to the AutoPark reservoir. Brake fluid is amazingly DISTRUCTIVE to a lot of the rubber and polymer items that are Have A Peek At This Website Typically present in systems created for ATF (automatic transmission fluid).
So – – We sense fairly cozy with expressing that we’re addressing a situation which can Typically entail some choices. Unlike several AutoPark malfunctions which have to have rapid notice, normally of leaking seals, or perhaps leaking seals, We've some selections:
