I was driving the other day. And out of nowhere the brake light on the dashboard came on. For no apparent reason. And i kno it comes on when the parking break is up. And i kno thats not what is causing it cuz i messed with that already. And now when i back up i notice a very loud squeking noise like finger nails on a chalkboard only in reverse, and its coming from the drivers side rear wheel. I have a 94 accord EX with rear disk. Does anybody have any clue what this might be that would trigger the brake light to come on?

 

Is it the one in the back (trunk area) of the "car diagram" in your guages with the words "brake lamp" written on it? If it is so, then one of your brake light bulbs blew out.

 

No its the one on the dashboard that says "BRAKE" with a red light behind it. My third brake light has been out since i bought the car but the light on the dashboard that is supposed to tell you has never come on. The light im talking about is the one that comes on when u pull up the emergency brake lever. And one day it just came on when i was driving. Yet it has nothing to do with the switch for the emergency brake cuz i messed with that already and thats not the problem. I need to kno what else would cause that light to come on? And yes my brake level is fine too i checked that as well. Anybody got any other ideas?

 

This light comes on for 2 reasons. Low brake fluid level and e-brake up. Maybe the ebrake switch is getting loose. Try wiggle it a bit and see if anything happens. It is a mechanical switch so once you lower the e-brake it should push the switch in. Maybe try unplug the wires from the back of the e-brake switch and see if you can bridge the connection. If the brake light doesnt go out, then you know it has nothing to do with the e-brake switch.
I have no idea how to test the low brake fluid level. Someone suggested pulling off the brake fluid reservior cap and wait awhile then put it back on, then disconnect your battery to reset everything and test to see if that will fix it.

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">Brake Fluid Level Sensor
If the fluid level in the brake fluid reservoir drops to an unsafe level, the BRAKE
warning lamp on the dashboard will illuminate. This simple circuit is controlled by
the brake fluid level sensor, located in the cap of the reservoir on the master
cylinder.
Wipe the cap and reservoir with a clean cloth, removing all dust and road grit.
Unscrew the cap about 1¤4 turn and lift it up. Under the cap you'll see a shaft with
a circular float on it. The bottom of the shaft contains a reed switch; the float
contains a magnet. As long as the fluid level keeps the float near the top of the
shaft, the reed switch is open. When the fluid level drops, the float drops down to
the reed switch causing the switch to close. The circuit is completed and the
warning lamp comes on.
Since the sensor and float are
