does anyone else have this

when the car is cold in cold weather backing out of the driveway your rear brakes hum periodically, doesnt happen when going forwards only backwards, and goes away once the brakes warm up.

 

adjust the rear drums so they just barely drag when yoou spin the drum

remove wheel and drum, turn starwheel to adjustt the shoes, put drum back on spin and repeat as needed

 

discs y0 lol

 

i get that too- i wonder if it's anything to be concerned about?

 

got it happening to me too, goes away when warm, and happens going forward

 

It's normal, my last two cars with 4 wheel disk brakes did the same thing.

 

can anyone explain what it is?

 

sorry man now i feel dumb

 

wow that same thing happens to me too!! I thought it was just my car!

 

happens here too, like said above...it goes away once the brakes, and car is warmed up, so im not concerned
