I just bought a preowend RX330 and when I break not all the times but sometimes i hear like a knoking noise under the car. Not sure if it's coming from either side of the tires, but does anyone know what this might be? It's not loud or anyhting but I can fell and hear it when I press down on the breaks. I read on another posting that this might be the calipers or pads that need to be adjusted, but I have no idea...if anyone out their can help me figure this out I'd appreciate it. I hate to take to the the dealer and being a female be talked into major repairs when I dont need them.
Thank you,
Brenda
