Very nice looking parts. I have a used setup I plan on doing (its on the list) to a 1983 GP I have buried in one of my buildings, if I live long enough. Keep us informed. It's nice to see a write up before tackling a job like this. Thanks.
The 2wd drive is a rare option up here, especially on later models. What year did they start coming with those brakes? I am also not sure about 14" wheels fitting and sealed bearings seem to fail eventually.
They are 2 wheel drive Blazer Xtreme front brakes.
The advantages are sealed bearing hubs, larger rotors, dual piston calipers and all off the self parts when you go to your local parts store.
From what I am told 14" rims fit. I know for sure 15" and up rims fit
Parts needed from donor vehicle are
Brake dust shields
Hubs (or buy new)
Rotors (or buy new)
Calipers ( to use or use as cores)
Some Permatex to seal the ABS sensors
Some also take the steel brake line frame mounts where the rubber line meets the hard-line.
If you use the Blazer mounts you will have to bend your hard-line down.
You then do not have to cut the rubber boot off the GBody brake hose.
If you take the Blazer rubber brake lines you will need a thread adapter to fit your GBody hard-line.
Another is when they are extra long is rubbing. My 94 Z71 I switched to braided hoses, they were way long, so they could be used with lifted trucks. They actually contacted on tight turns with the dust shield, they were so stiff but the braking improved.
