Brake bias control when upping the rotor size in the front and changing to disc in the rear made complete sense to me. I have done this on a couple of vans now that had more horsepower swapped in and the drivelines beefed up. I used a Tilton brake bias found in most speed shops to control the percentage of balance front to rear when braking. In lay persons terms it is like adjusting the fader on your stereo front to rear.
I have different settings marked on the dial for easy switching. One for everyday driving, one for lead foot driving and one for towing my trailer. The trailer is an aluminum utility with electric brakes as well.
The settings take some driving to figure out, but starting at a 60 front 40 rear setting was a good baseline.
As for cost, it was bucks to do this. I replaced the entire braking system from master, to booster to lines, upgraded to stainless braided at flex points, larger front disc, disc rear, Tilton bias, ATE superblue fluid.............and all the labor. Material cost at retail would be roughly $1500+ if you use the kits available from Small Car or GoWesty.
My reason for doing all of this is that I have worked on and drive a SVX conversion Syncro van and feel that balanced power to braking scheme should be used for safety reasons. Running larger rims and tires on a Syncro alone will show you that the brakes need to be well maintained to have the stopping power needed for emergency stops. Add in more horsepower, more engine weight in the rear and larger wheels to bring the revs down and stock brakes just don't cut it.

Hi John
I might suggest if the rear brakes got adjusted on a regular basis then you
would not go threw pads as often
When I adjust the rears I pull just the drum adjust, and test fit the drum
back in place. I find this improves braking
