Subject: 1994 Mitsubishi Galant brakes
Question: Yesterday I noticed ABS dash light would come on intermittently. When I parked, my brake lights stayed on even with all car lights turned off. There is no problem with car's braking ability. The only way to turn off brake lights is to pull fuse. Is this a repair that I can do myself or will it need electronic diagnosis?
Answer: Paul,
There is a couple things you can check yourself.
One simple thing to check is inside the break fluid resevoir. There is a float that is attached to the switch that turns on the brake light when the fluid gets too low. Check that float to be sure it's free to move and not sticking. A few pokes with a screw driver will do to see if it's sticking or not. Be sure the screwdriver is CLEAN.

Your brake pedal may be misadjusted. If the master cylinder is worn, the brake pedal may sink down and that would cause your brake lights to come on even when the car is turned off.

There may also be a problem with your car's computer. Read this article for further information:

If your ECU has gone bad, you will get these strange problems.

If you can't find the problem, then have your ABS system inspected by a qualified technician. You may have a problem with the ABS module itself.
Good luck!
