Is voltage 8.6 at other wheel(s)as well,and is/are it/they fully engaging? If yes and yes,it's time to pull the brake mag and check it and connections.
My knee jerk is that a wire or connection was damaged during the blow-out. Did any tread peel away and flop around?
A few tests.
Unplug 7 way cord and pull the break-away device (make certain house battery is charged and online:W) to see if brakes engage. If yes the problem is outside the brake assembly on wheel and wireing to front of trailer so look from front of trailer going toward TV and controller. Reset break-away to prevent discharging house battery. If no,test as below.
There should be no resistance between chassis of tow vehicle and trailer frame to begain.
If brake mags are grounded to frame,there should be no resistance from mag - wire to frame.
If mags are grounded by continus wire from TV,should be no resistance at connections.
That should get you started. If this doesn't find the culprit,we will go to + side and controller next.
when i got the 8.6 volts the tire would still spin freely when brakes were engaged, I can hear the other 3 tires engaging (buzzing noise) but none at this tire. when the blowout happen the tread did flop around and dash read trailer fault for a second but the wires look fine up to back of break assembly
