I'm having issue with my 93 F350, the brake light and antilock brake light stays on and won't turn off, any ideas? Thanks.

 

same problem here on my 1990 f-250 my anti-lock light is always on and for a while my brake light was as well but that was right after i took off the caliper to change wheel bearings and i had to do some rewiring and it came off but i also added some fluid so im not sure which one it was i am also interested in an answer for this

 

How does your pedal feel?

Low fluid and park brake engaged both turn on the same red brake light, so check those two places first.

The RABS is a common wear part at the age of these trucks, do a search on bleeding, replacing or bypassing the rabs to get your brakes back.

Less than a week ago I had a rear wheel cylinder go bad on me, replaced and bled the entire system then the rabs light came on and the brakes got really really soft. Replaced the rabs with one off a parts truck and bled again, no more lights and brakes like new. All this started right after adjusting my rear brake shoes... Check very carefully for leaks, brakes are important!

the thing is i didnt mess with the brake or anything, it just stay on one day when i started the truck and wont turn off since then. I'll check the brake fluid and see if they are low. I made a typo, the truck is a 87, not a 93, not sure if that makes a different.
