I have an 89 4.0/aw4/242, no ABS. it has lately started showing the red light on the dash that says brake sometimes. by sometimes i mean sometimes it comes on sometimes it goes off.
the jeep stops fine. fluid is at the same level it was when i replaced pads 4k mi ago. no wheel cyl or caliper leaking. ebrake not on. and ebrake switch seem to be working properly when tested with DMM. i will be honest here and say that the ebrake gets used only a couple times year( inspection and maybe once or twice to make sure the cables haven't seized)
it doesn't appear to have any relation to anything else. ie not on/off with braking. sometimes hot sometimes cold. sometimes at idle in park sometimes at highway speeds.
i'm stumped.
what else am i not thinking of that can cause that light to go on. maybe a bad sensor?
