Do I NEED THE W8001667 BRAKE LIT? WE HAVE THE Allison 5 speed transmission but brake works very well as mh is not able to move at all when parking brake engages.. ( Philip Gilmore, 07/13/2022 )

Phillip,

    In your other comment, you said "Brake has locked three times in the last two years" did it apply while the coach was moving? Or, it would not release when you took it out of park? If it applied while driving I would encourage replacement. Otherwise if it has not applied while driving, and holds when you give it throttle with the engine running, coach in drive, and the yellow push/pull button out, then there is no need to replace it.

Ordering whole kit
Brake has locked three times in last two years. Tow is expensive but most mechanics do not understand it. So needless work is done. We are on the road so will have it shipped to mom in laws home (26 N MAIN ST, ALBION, PA 16401, WE STILL HAVE 300 MILES TO GO TO GET THAT FAR. IF LOSS OF 12 VOLTS IS THE CAUSE (MAYBE ON GROUND SIDe), WHICH WIRES SHOULD I APPLY 12 VOLTS (+ AND 12 VOLTS --) TO IN AN EMERGENCY.?
( Philip Gilmore, 07/13/2022 )

Phillip,

    On the 14 pin connector at the controller, with key on, power should be found on pins 1 and 10, and ground on pin 14 for the 12vdc supply.

Does this prevent the parking brake from engaging while underway even in the event of either a voltage or hydraulic loss? If this occurs can the vehicle still be driven. ( Rick Crosby, 05/18/2016 )

Hi Rick,

In the event of an electrical issue or voltage loss the valve will not allow the brake to engage and will allow you to continue driving.

In the event of a hydraulic loss, as long as the leak is not at the brake itself or in the metal line between the valve and the brake it would prevent a lock up. If the leak is at the brake itself, the brake needs to be replaced anyways and the likelihood of a leak at that metal line is very low.
