Brake Problems

[big jimmy 91]

My 91 jimmy had the brake light come on and stayed on about a week ago...
After looking for the obvious things , nothing seems wrong

Tonight the light started flashing in a constant sequence of four times , a pause , four more... and so on

It also seems that the brakes have become super touchy now , just look at the pedal and they lock up

Does anyone have any idea what's up with the light and how touchy they are?

This truck is all stock as far as I know and has some sort of anti-lock system on it.

Any help would be appreciated as it is my only set of wheels right now

IIRC the light has two purpose's one to let you know when the e brake is on and second to tell you when the brake system is under 50%, so you might want to take a peak at the master cyclinder for fluid level, check hard lines for kinks or leaks and really just every line on the truck, if you dont find anything i would then bleed all four courners to make sure that fluid is getting to them, being a 91 i think the only difference is the t case not having a mech speedo but could be wrong

Does anyone have any manuals for brake systems on a 91 jimmy , or know how the abs.system woks on them?

Last try , no one has any info?

The light serves to indicate the parking brake is on, and also, if there is a problem with the computer controlled systems, to indicate which part is potentially the problem via a code. Sounds like it is giving you a code 44, but I didn't think that was something the system would do unless you used the paperclip trick to jumper ALDL connectors A&B.

In any case, probably a problem with the ABS system, just guessing based off of your symptoms.

Thanks for the info

Could anyone tell me what a code 44 would be?
