Hey yall

I say just a couple of weeks ago I started hearing this lil squeak noise by the drivers side rear wheel when I backed up and I was like oh it's probably nothing...

But now is pretty loud and now it hapens when I'm going forward too...
Could it be that I need new break pads and may be new rotors?

I have some extra cash which if I need to I can probably spend on some Brembo blanks...

But what do you guys think...n just in case it is the rotors n all what kind of break pads should I get so I don't get all that dust on my new wheels -=/ ?
Some of my friends said Axxis??

Any help I thank yall in advance
