How long has it been since last brake pads/shoes replace?
A vehicle has a set of four brakes. And you think you have break in the brakes. I would have a shop that specializes in doing brake jobs. Let them inspect the whole system. It sounds to me that your pads are wore out and you have metal on metal. You should not be carrying a infant in a vehicle that very likely will not stop when you need to.
instead of the brakes, it might be the rotors or a wheel bearing ! when it comes to safety you can,t be too careful so i recommend you to have a brake mechanic to check it out for you !

I have a 2008 subaru legacy and the breaks have been making a sound like a ball rolling when I hit it and it doesn't start til I'm driving for like 10 minutes. It has been doing this for a couple months and my bf dad friend didn't see a problem but it has to be something?? He didn't do a full check and the break light isn't on check engine Is tho but that's from the o2 sensor. I have no trouble hitting the breaks I have a 6 month old so I don't wanna be driving it and all of the sudden they don't work!. It doesn't make any other noises that I can really tell maybe a little creeking sound and then the rolling like a ball is rolling in there lol it isn't that loud I don't think it can be heard outside the car what can this be?
