Just had brake pads replaced and rotors resurfaced. When pushing on the brake while backing up, I hear a loud groaning noise (almost like metal stressing or rubbing together). It does not happen when braking while driving. I was reading others were having similar problems but ours only happens when I back out of the garage. I haven't tried backing up anywhere else but I assume I would get the same results everywhere.

You are most likely correct that this is going to happen anywhere. However, what this noise is, is when the pads and rotors are not fully seated or you have what is called a glaze on them. Basically you have an issue with the way the pads and rotors are mating.

Here are some guides that will help with this:

If you had this done, then I would take it back and show them the issue. Keep in mind it may not do it when they are hot so you may have to leave it with them overnight so they can do it in the morning.

When they get hot the mating between them can change and it will stop.

The other possible cause is the rattle clips that they used are not holding the pads firmly and it is causing this noise. This is more rare but either way, this is related to the new pads and resurface rotors. Lastly it is not uncommon for this to happen when you replace pads and resurface the rotors.

Let us know what questions you have. Thanks
