ICE

Hey everyone now I know this is an EV forum but I had a question for an ICE that I just cannot pinpoint to get it right.I have tried websites like Alldata and Identifix. My technician and I have been working on our customers pick-up truck for like ever. We are doing a full round brake job for a 1993 Chevy K1500 4WD pickup.
It's a piece of crap im sorry. We installed the brakes front and rear, it also needed a new brake master cylinder. One of the worst things that I hate about brake jobs is bleeding the brakes, I freakin hate that!
