Brake light randomly on??
So a few weeks ago I slid in a ditch. No major damage (that I know of) but a bent up brake line. The brake light was on after the accident. That was fixed and is leak free. Me and my dad bled the brakes properly. and the light went off about 3 days later. However it came back on about 4 or 5 days ago and has stayed on. What could cause this? The fluid level is fine, its actually over filled by just a hair to be safe. There is no air in the lines. The brakes feel excellent just like they always have. Could it be that the fluid level sensor went bad randomly? Or is it something else?

Check the switch behind your break pedal. |

If its the fluid level sensor, could I short the two wires together on the sensor and possibly trick it in to thinking that it is working correctly if thats whats wrong?
I will also check the ebrake switch. I drive around with the ebrake up one click all the time so maybe that has gone bad or something.

I would check the resistence, amps and volts of the sensor if you have a dvm you never want to short anything.

yeah you could unplug that sensor and put a paperclip across the terminals and see if the light goes out.

try the fluid sensor first and if you cant get the light to go out that way then try the same thing with the ebrake switch. but i think you will probably find its the fluid switch.

if it was the ebrake switch, it would start to chime after moving at 5mph.
