Having done this mod in different ways, I'm gonna point something out to you guys.
You are leaving a large amount of overall braking on the table when keeping the Distribution Valve.
Your brake line inner diameter is .100". Stock.
Where the fluid for the front brakes passes through the Distro block, it is metered to .050". That's an area of .00196"
If you were to use a ZJ prop valve, which is metering the front brakes through a .078" orifice, and eliminate the LSV as a matter of course, because you would use the prop valve to proportion rear braking, the area for the fluid to flow would be the area for the fluid to flow to the front brakes would be .00478".
If you use an XJ prop valve, which is metering the fluid to the front brakes through an orifice matching the brake line ID of .100", and eliminate the LSV as a matter of course because you would use the prop valve to proportion rear braking, the area for the fluid to flow would be .00785".
By allowing the fluid to flow to the front brakes through an area of .00785" versus an area of .00196". That's a lot!!!!!
I've tried it both ways. Now on MJs I ditch the distro block, T the front brake lines together, eliminate the finicky and kludgy LSV. An adjustable prop valve for the rear brakes is $40 at Summit Racing......
