The brake light on my 08 F150's dash comes on and off whenever it feels like it. Have had the brakes inspected and they are good and the e-brake switch is okay. Is there a fluid level switch in the master cylinder? The level is okay but maybe this switch could have a bad attitude? Does anyone have any experience with this problem?
Thanks in advance for any feedback!

 

I know you said the e-brake switch is good but on my last truck I had this problem and setting and releasing the brake made the light go out. I came to the conclusion that the spring that returns the petal to the off position was probably worn.

 

My 06 does the same thing. If I pull the E brake pedal back it goes out. I always used the E brake when I put my truck on ramps to change the oil. Now I don't use it and just chock the rear tire. With 187,000 miles and changing oil every 5000 miles, that's a lot of E brake uses.

 

I changed the front brakes on my 2007 f-150. When I compressed the pistons on the calipers I forgot to uncap the master cylinder(I know guys. I've changed 100s of brakes. This was the firs time I forgot).anyway as a result my brake light stays on. A mechanic told me it could cost a thousand dollars to fix. I DONT have any problems other than the light staying on. Good luck.

 

Disconnect the fluid level switch on the master cylinder and see if the light goes out.

Get a new (honest) mechanic.

 

This is an old thread, but a common problem. One of the plugs on the back of the instrument cluster can cause intermittent "e-brake light on" illumination. There are you-tube videos showing/demonstrating the loose plug & light. I'm not sure of a cheap fix for the problem.
