Rear disk upgrade

[swamprat]

I se where people are using explorer rear calipers and mustang calipers. In the axle swap chats people have used chevy Malibu calipers on the rear when 9in is swapped in. Malibu calipers come loaded and no core charge so was thinking of trying that. My brake master might be bad. I have an explorer 4 disc master in storage I could use. If I swap masters and keep drums will there be any issue? If I do that I will be making brackets and getting calipers in mean time.

The proportioning will probably be off unless there is a separate proportioning block.

I would test it to see how the truck stops before taking it on a real drive anywhere if you are going to commit to the swap.

You might be ok. There are people who never swap their master when doing the disc conversion and never complained about it. Better to be safe than sorry.
