Hi there. Welcome to our site!

If the noise you describe was caused by other than the brakes, it would manifest itself all the time as the vehicle backed up - regardless of whether or not the brakes were being applied.

Looks like you have some options at this time; taking it back to whomever fixed your brakes or doing the job yourself. If you decide to do it yourself, all my knowledge and resources won’t help you if you…

… don’t have tools or the skill to use them

… don’t know there will probably be some special tools and equipment needed for a proper repair

… don’t realize it may take a few back and forth replies to solve the issue

Having said that, how would you like to proceed?

I'm sorry. What are you saying NO to? Does that mean you don't want to do it yourself? That's OK.

Best Regards.
