im wanting to put the 31 spline 8.8 under my 83 ranger and i also want diskbrakes in the rear

 

[kennykenny]

I'm not sure about the what works with what as far as brakes, but the spring pads will need to be relocated to the top of the axle and shock mounts welded on.

 

[johnnydragger]

i do want to lower the truck is the sping pads the same with?

Im confused. You wont need to to replace the master cylinder, stock will work just fine. As far as the spring perches go, if your axle is spring-under and you swap in the xplorer 8.8, which is spring-over, you will drop about 4 inches. And yes, the perches are the same width, it will bolt right up. But like kenny said youll have change the shock mounts.

On an 83 you will need a new master cylinder. You will need the one from the explorer or from a truck that came with rear ABS.

Alrighty..

I've read the back and forth debate on explorer forum and other sites about needing to swap the master when converting to explorer rear disks. Someone mentioned that the disk brake masters have a larger bore, to move more fluid. I decided to go ahead and get the master from the truck i pulled the disk brake 8.8 out of today.

Disk brake rear that will be going into my explorer:

Disk brake MC from a 95-97 on the right, vs a drum 91-94 master. The 98-05 masters are different part numbers from the 95-97 units.

Disk 95-97 left, drum 91-94 right:

Disk:

Drum:

Common wisdom says that you need to swap the disk/drum proportioning valve out when going to rear disks. Well... my '92 explorer with rear ABS does not have a prop valve. The front disks are plumed directly to the master, and the rear's go from the master, to the abs valve, to the back. So, that told me the proportioning must be in the master. That convinced me to go ahead and swap to the disk brake master when I do the conversion. The 91-94 explorer lines screw right into the 95-97 disk master.

I would assume that any other Gen II would be the same (Ranger/BII)

Now, those with an 84/85 BII or 83-85 Ranger are kinda screwed. We use a completely different master than the 86 and later trucks, and we will have to cut the lines at the master, swap tube nuts from a genII, and then reflare the lines for a bubble flair to use the disk brake master:

You will also have to get creative with a mix of later model ranger parts to hook up the e-brake cables.

has anyone swapped the axle drove it felt how the brakes were then swap the master and felt the difference?

I have heard many people who have not swapped the master and have had no complaints.

 

[johnnydragger]

so will the master off the newer explorer bolt on to the booster of my 83 rangeror will i have to swap that also?

 

[Sasquatch_Ryda]

It'll bolt up just fine to the old booster.

 

[johnnydragger]

will the fx4 rear end with the explorer brakes fit under my truck also? and will the shocks bolt up?

 

[Sasquatch_Ryda]

Yes, yes and yes
