so my brakes have been wonderful so far. granted i drove a lot of highway for a while. i have 58,000 miles on my jeep. this morning i notices a noise while driving. not high pitched, but a faint squeal as i drove. when i hit the brakes the noise went away. could this be my brake pads or...

Has anyone installed a DashHawk? (ie. DashHawk.com) They look pretty useful.
