I've had my '04 for almost 5 years now and in the last week I've noticed a knocking sound coming from the rear right wheel when braking at slow speeds.

The sound isn't loud and can only be heard when the A/C and radio are off.

Any ideas what could be causing this sound? Also the brakes squeak from time to time.

Sorry if this has been asked and answered already or if this is in the wrong forum. I tried searching first.

 

have the brakes inspected- the squeel may be the low pad warning tab hitting the rotor

 

I have an appointment setup with my dealer tomorrow. Will update here when I have more info.
