so iv got my 91 4x4 and the abs has never worked. prolly the modulator which is an expensive fix. long story short, i got air in the system and cant get it out WHAT WOOD I HAVE TO DO TO BYPASS THE WHOLE ABS AND RUN DIRECTLY FROM THE MASTER CYLINDER LIKE THE TRUCKS B4 ABS??

 

New lines basically. I did it on my 90. Just run new lines from the master down. Also on mine I just unpluged the abs and it shut the brake light off too

 

yeah i dont care if i dont have abs, iv nvr had it but rite now i have 0 brakes and iv been bleeding forever iv ran 2 quarts of brake fluid throo and nothing has changed

 

i was looking on ebay at the s10warehouse site they have abs modules for 50 shipped.
i am looking into what the swap involves.

 

i actualy alredy have switched it out from another blazer i keep for parts. figuered that on wood have less air. then i scanned it and bout 10 codes came up everything to no wheel sensors to shorts but that didnt do anything to harden the pedal i have a hunch i need to bench bleed the master again but its going in the shop next week they can figure it out then ill just ask wat they did
