well a mustang is a lot more car than an integra for starters....

just pop off the wheels and brake calipers and see how your pads look. if the stopping material is skinnier than the metal itself on the brake pad then replace them and bleed them out real good.... when i got my 04 last week it was the same way, i did a brake job and it's fine as frog hair
BTW be sure to open up the bleeder valve on the caliper when you go to push in the front pistons, and screw in the rear so you don't damage the ABS module.... opening the cap on the master cylinder IS NOT enough!!!!!!!!
