If your brake light is not coming on, you might have blown a fuse. You might also have a bulb that is no longer working.
If only the red brake light is coming on, the parking brake is on or the brake fluid is low. If the yellow abs light is also on, the abs computer has detected a malfunction and set a code.
your brake fluid is probably low or very dirty.
Your brake fuild might be low.
If the red " BRAKE " light in your dash is coming on , then either the brake fluid level in the brake master cylinder in your engine compartment is LOW or the parking brake is on
The grinding noise is the brakes pads proably the noise is in the front. The front brake pads are easy to replace and is a do it yourself sort of thing. My guess is your brake light is coming on because of this condition. I assume your brake light has been coming on for a little while now.
needs new alternator
check for blown brake light bulbs and broken wires. also check brake light switch on brake pedal
bulb is out The bulb has two elements in it, one for the tail light and one for the brake. The brake one is also for the directional signals.

More than likely low brake fluid level in the master cylinder. Check it.
