91 4.0 4x2 5spd While starting out or driving, hit the brakes, my brake light comes on and after antilock comes on, then go out simultaneously, doesnt happen all the time, brakes work good, I know eventually I will need new brakes, could low brakes set off these lights?

 

if your brake fluid is extremely low...check your brake fluid...that can cause it

 

low brakes would trip it. its either fluid leak, low fluid, or electronic issues.

 

i didnt even know 91s came with abs

 

Thanks I didnt think of that, I never had the fluid go that low in any of my trucks to trip the lights, I will check fluid, probably low due to I need brakes soon, I know my 92 F150 is supposed to have some kind of abs system too.

 

I checked the fluid and it is half way filled, I know the front brakes are stopping the truck, possibly replacing rear brakes will help.

 

halfway? hahahaha that's why. it has to be to the bottom of the filler neck. no the to the top though. it expands. just to the top of the reservoir.

thats so frikin low.

 

^^^ no mine in my 94 the same exact abs system it doenst set the high off till the res is almost completely empty.
