I recently purchased a 1988 GMC GMT400 Singlec ab Short Bed 2wd that has been frankensteined to say the least. It has a 400sbc, 95 dash and seat and the rest appears to be 88. The guy i bought it from knew absolutely nothing about it.
Driving home i realized how sketchy the brakes really were so I replaced the master cylinder with the NBS model and i did Russell brake hoses.
Now i'm to the bleeding part and i have some sort of Kelsey-Hayes ABS unit that i've read are a nightmare to bleed or need to be taken to a dealer. Ive considered deleting the ABS but ive only found guides videos of the RWAL. I have also read that I can buy a scanner on amazon for about $100 that will bleed to brakes in OBD2 vehicles but with all the hackery on this truck i have no idea if my truck is OBD1 or OBD2.
OBD2 Scanner with ABS Auto Bleed FOXWELL NT630 Plus
So i guess my main questions are:
Did 1988 have this ABS (pictured below) as an available option
Is 1988 OBD1 or OBD2 (pictured below of what it looks like in my truck)
Are there any guides of removing this type of ABS and replacing it with a proportioning valve
Any additional information would be greatly appreciated i'm feeling a little overwhelmed currently.
