Brakes?? Ford 8.8 swap

[icdpride]

Just "Completed" a ford 8.8 rear end swap on my 1982 volvo 240dl wagon. With this I have swapped over to the explorer rear calipers, I know the rear proportioning valves for the volvo brakes are notorious for being a pain to bleed the air out of. Should these be removed with the explorer calipers and just run a central proportioning valve?

Or do I just keep those and bleed as normal?

Those are reduction valves, so you should remove them with the ford calipers. What are you doing for the front brakes? I would suggest running new lines, a single line from the rear to a wilwood proportioning valve inline, and a single to the fronts.

Yeah that's what I was thinking.

Fronts I have s60r calipers

Would I keep the factory master cylinder or switch it out?

You may be able to keep your stock master with the s60r calipers. Check out the Dave Barton website, there should be some info on there.

The stock non-ABS 240 master cylinder is designed for a equal volume in each circuit. Which means it can only be used with a diagonal split system.
If you want to swap to a front/rear split system you will need to change the master cylinder.

I would get rid of the factory octopus and run the fronts of the rear larger bore master and the rears can run off the front smaller bore master. I hated the way the brakes felt the diagonal connection on the factory octopus block. One front wheel would lock up. I switch to an ABS master with willwood reduction valve for the rears at its least reduced settings. R calipers all around. Brakes feel amazing and decently balanced.

I didn't feel the need to change anything when I used the Explorer rear brakes, they seem to have a little more stopping power than the volvo rear brakes so I think you may find too much rear brake without the reducing valves.
