I have a 1992 Ford F-150 regular cab with the 5.8 in it, recently, probably within the last month my parking brake and rear abs lights have came and gone on my dash. I've looked up to see what the problem is many say check brake fluid, I did and the reservoir is at the max line. Anyone else have some ideas to what it could be? Possible fluid line leak? Not to sure would rather try to diagnose the problem myself rather then going to the shop and spending a fortune for a easy fix, if it is an easy fix.

Thanks for the help.

Possibly ABS sensor on rear differential or wires leading to it.

Both lights on means hydraulic problem.

I also have the same problem. Hydraulic issue meaning what exactly. Brakes needing bled, maybe air leak at booster, system failure etc.
I know I need shoes and already have them to put on. Could worn out shoes be the problem also?

Bad master, leak, air in the lines...

When the lights are on you are gonna have to pull the codes to find out what it is exactly.

Not when they're both on. Just ABS light ABS problem. When the BRAKE light is on for a brake related reason the ABS light automatically comes on, it disables the ABS. The ABS light doesn't come on when the parking brake is set, just the BRAKE light.

I changed my front brakes pads due to squeeling about 2 weeks before my lights came on and did notice that the passenger side pads were worn where my drivers were little over half worn. Figured maybe caliper was sticking. Checked them before reinstalling tires and they seemed to release evenly but not sure of pressure. Doesn't pull to one side when applied. Wouldn't think it would be the problem of the lights if it never caused the lights to come on before wearing out the pads unevenly before.

Installed my rear shoes yesterday and everything went well there also. Gonna bleed all my brakes this weekend with my daughter's help and hopefully eliminate the lights. A friend said that when shoes or pads are replaced the brakes should be bled right after. Is this so? I can't see air going into the lines just by the changing process.

I appreciate the help and hope to fix it, either way I'm sure I'll be hitting up the forums.

No you don't have to bleed when changing pads or shoes, only if the hydraulic system has been opened.
