hey guys i need to know why my brakes screech all the time, i changed them about 3 weeks ago and they sound like I'm driving a truck its really annoying driving a hot car but people looking at the car for the wrong reason

 

Should let us know what brakes you are running. Did you break them in according to manufacturer's guidance. Some folks have used different shims, anti squeal grease, etc to help as well. 1st step, let us know what you are running.

 

Are you using the angled, stock rear shims. The rears are more prone to the wild sounding squeal. There angled for a reason
