Can I plug 1/2 of my Master Cylinder?
 

I have a 96F-250 with a dual feed brake reservoir.
I have replaced all of the front brake lines.

I need to replace the rear lines too (there's a leak), but I also need to move the truck asap, and only a few miles away.

Is there a plug or other way to seal off the rear feed "right at the reservoir ", just so I can drive it home?

I do have 33" tires on the truck (no lift), but I figure if my front brakes account for 70% of my stopping power I should be ok?

Any other suggestions?

If I can't block off the rear feed, is there any way I canget it "in and out of gear" and drive it onto a rollback? Being that it's an automatic transmission,how can Ido that? without brake pressure?

Thanks so much for any help.

I realize that this is a little late, but my brother-in-law did that on a Ford Ranger about 20 years ago. He was about 400 miles from home when his rear brake lines started leaking. He disconnected the rear brake lines at the proportioning valve and put in a plug he bought at an auto parts store and re-filled the resevoir. He made it all the way home without issues.
