So – – Assuming the cables themselves are in fantastic affliction, this leaves our remaining variable to generally be the long hex nut on the actuator shaft – – depicted as #1 from the illustration previously mentioned. It is essential to notice that this actuator is demonstrated within the BRAKE ON condition – – Check out To visualise IT With all the SPRING COMPRESSED within the BRAKE OFF condition. With all the brake OFF and the actuator shaft extended to its mechanical Restrict, we would want to adjust the very long hex nut just to The purpose where by there was no slack while in the cable program – – no more, no fewer.

Clear away the relay through the socket/connector. Identify The 2 terminals in the connector which might be fed by The 2 LARGE wires.
After you have taken off the four nuts from their studs, and you have disconnected the incoming line, you could merely pull the cylinder off in the studs.
Nearly all of the subsequent visit this page is stuff Now we have lifted from manuals and this kind of – – There will pretty very likely be some duplications of material involving the varied produce-ups.
This information sheet is new, and is also penned to address an AutoPark parking brake challenge that happens to be fairly prevalent in just the previous couple of months.
