when you say there is no indicator, do you mean the illumination of the letters on the shifter plate (next to the gear lever)? or on the dashboard itself (between the speedo and tacho)?
if you mean on the shifter plate, if that is not lighting up when you have your headlights on at night, then its mostlikely the bulb in there has blown, so that needs to be changed. If your referring to the lights on the dashboard which indicate what gear you are in, it is dependent on the grade of your car, ie: the Executive and CSi models didnt come with that, but I believe the CSX and Ultima ones did. If they do exist on there, but simply aren't lighting up, then the bulbs that illuminate the dashboard and those shifter lights have blown mostlikely.
with the brakes not sure what it could be, could be a number of things; need new brake pads, rotors warped, or it's just like that (some performance pads/rotors cause slight sound sometimes), or it could be all of the above :P
