Constant beep even while off after pop sound from rear brake

Holy moley. So you just bled brakes like a regular Corolla or VW??? Or did you use the method from the forums here? The smoke was probably from dragging rear shoes.whick mite have ruined that set of shoes. Working on fronts I'd left rears alone . Left brake fluid alone initially. Till I got it back to regular braking . The front and rear brakes aren't connected per se or for this operation . Get the smoked side apart first . See how badly burnt shoes are .. shoes are rear pads .

 

In the correct instructions you were supposed to take a relay out of the front fuse box I can't remember if that's for bleeding the back or the front but you did both so at some point there should have been the relay taken out of the front fuse box and then you crack a bleed screw and watch air then fluid then air then fluid or something till it's solid fluid close the bleeder look at the reservoir and route to the other bleeder on the other side of the car Make sure it's topped off do the same to the other side till it's solid fluid no air check the reservoir again coming up and there you go The back should have been done first generally start from the furthest away and work to the closest I lost those instructions but if it wasn't done that way then there may be problems.
