Strange Braking Sound Persists after Brakes Fixed

welcome!
how long have you owned the car?

who did the brake work?

how many miles on her?

 

have you owned it since new?

what did the dealership think?

 

May or may not be the issue, but one thing to check, if you can manage: chock the front wheels, release the parking brake, raise the rear till the tires are clear, then see how freely they spin. Should be something like this, if they didn't screw up the rear brakes.

The rears are tricky, need to be reassembled with the pattern on the caliper piston face oriented like an "X", and well seated against the brake pads thus. If it does manage to rotate, you'll get a constant drag, bevelled pad wear and scored rotors.

 

does it happen around 6mph when regen braking cuts out?

 

could be the normal friction cut in

 

Can you pinpoint at what second the sound occurs?

 

it seems to be seconds 6,7 and 8.

 

hey mendel, double posting from bc, canada

 

it almost sounds like the pads are loose, or grabbing

 

reading your first post again, was the sound there before the rear brakes were redone, or after?

 

I've just listened and heard nothing out of the ordinary. But I didn't use headphones.

I once did a little enhancement in Audacity for somebody's weird-sound recording, made it easier to pind down. But I'm not where I can conveniently do that just now. Maybe somebody else can?

 

seems to pinpoint the rears, almost like something wasn't connected properly and came loose. i'm not an expert on what parts go in there and how they are connected.
menders X alignment is important, but i would think the sound would have developed right away.

maybe take it to another dealer and have them inspect it?
