this seems to be the trend today. hahaha
i would never ever do a rear disc conversion on these trucks, especially with those junk eldorado calipers.
you're sacrificing pad surface and a good e-brake when switching to discs. 3" pads and 1 ton cylinders are great on the backs of these trucks when properly adjusted.

serviceability is a huge bonus though!

FWIW: I did the rear disc conversion on my mess using the Eldorado calipers with E-brake. With the stock/OEM MC, I felt the pedal stroke was too long so, . . . .
- I changed the master-cylinder to one from a 1983 Dodge B350 gasser. It has a cylinder diameter of 1.3125" where as our stock/OEM cylinder is 1.125". That will move more fluid with the same stroke length compared. (Had to narrow the new cylinder's mounting holes to fit our power booster).
- Added a 10lb residual-pressure valve to the rear brake line. This reduces the amount of "Pump-Up required" if you will, with the rear calipers.
Works like a champ!

a RPV just keeps constant pressure on the brakes. many stock m/c's have them built in for rear brakes. as BC mentioned, tightens up the pedal.

And increases friction material wear. It's like lightly riding the brake. I lost a wheel cylinder in a dump truck once with this trick. Auto adjuster didn't work, wheel cylinder over-extended. I had to make a U turn taking the paint off both sides of a stop sign and peeling a set of duals off to keep from killing somebody.
