Why does your parking brake light stay on in your Camry?

Answer 1

there are only two switches that share the brake light circuit,

One switch is under the hood,below the master cylinder is a brake line junction block,This switch only has one function,it trips its self and turns on the brake light on the dash when it finds any air in the brake fluid system at all,like if a brake line broke on you and you lost your pedal and pumped air in.

Has any wheel cylinders or calibers or brake lines been changed on your car? And this light happened right afterward?

If yes,then there is an air bubble in the brake system and it is probably located in the junction block by the switch,But you said the brakes are working fine,no low pedal.

If all above is ok and your pedal is normal:

The second switch that shares the brake light bulb on dash,

Is the emergency brake,

This switch turns the light on as soon as the emergency brake even moves on with the first click,

If you emergency brake is on the floor,on the left kick panel,and you push the pedal down to use it,

you will need to take a look under the dash where the e-brake pivots,there you'll see the switch,just reach up and disconnect the wire to eliminate this as the cause of your light,

If your emergency brake is beside the console,if you have a floor shift,The switch is down where the e-brake handle pivots,its harder to get to but unhook the wire,
