Ok basicly the question I am asking is I am putting the 8.8 rear inplace of my D35. My question is what all else will need replaced for my brakes. Such as the Master Cylinder, reservoir, etc... I know I will need to run all new brake lines. I am replaceing all the calibers now and going to have the rotors turned down.

You should be alright, just try them. Are they one piston or dual piston calipers?

If you wanted discs, I would have just got an 8.8
with discs already on it.
The cost to convert drums to discs, would be the same
as buying a complete 31 spline Disc brake 8.8.
I would just keep it drums, or get a good 8.8.
Then sell that one.
As far as the master cyl goes... You don't have to run any new
brake lines from the master cyl, just bolt on the new extended steel braided line
in back Down to the "T" box on the axle, then run 2 new steel lines out to the calipers which require
a short factory Ford rubber section to the disc calipers.
Drums dont require the rubber soft hose, the hard lines
thread directly into the drum's cylinder.

Marc it looks like the 8.8 he has is disc brakes.He says he is having the roters turned and replacing the calipers.I think what he ment by disc brake swap was taking the drum brake d35 out and replacing it with his disc brake 8.8

Oh my bad.
Trytan, all you gotta do is buy your extended brake lines...
There's 1 in rear & 2 up front. Hook them up.
Then you gotta make sure you have the Ford factory hoses
which bolt to the caliper with factory Ford banjo bolts. These hoses are like 10-11" long.
Gotta have them.
The new rear steel braided brake hose will come down from
the hardline junction inside the drivers side frame rail. This line drops down
to the center of the axle, and has a "T" junction box on the end. The junction box bolts
to the axle. This is where the line splits from 1 to 2 lines to go to each caliper.
From this junction, run two short 36" hard lines along the axle tubes, out to the
Ford short hoses. Then short hoses bolt to the calipers.
Calipers MUST mount with the bleeders ON TOP!
Or the system won't bleed.
Bleed the system properly, use fresh DOT 3 fluid,
make sure all line junctions are TIGHT because they will leak
if they're not tight enough.
Route your lines UP high on the axle so nothing will
snag on them. Dont crimp or bend the hardlines too sharp,
all bends gotta be smooth.
You Might need an Adapter fitting when fitting you rear hard lines
on the axle housing to the "T" junction box on the steel braided line...
I did when I put my 8.8 in.
Don't mess with the master cylinder for now,
it'll be ok. If you want to put a new master cylinder
in, get one from a 1994-1998 Grand Cherokee ZJ.
