9" drums all around...not diggin' it!

one more thing to remember when ever you are converting from drum to disk
drum brake master cylinders have a residual pressure valve in them that keeps a small amount of pressure on the brake lines, sort of like lightly resting your foot on the brake pedal, this is done in order to keep the seals in the wheel cylinders from collapsing and leaking, the amount of pressure is not enough to overcome the tension of the spring's on the shoes

if you try and use a drum brake M/C on a disk brake it will make the brakes drag causing rapid brake wear, brake fade due to heat, loss of fuel mileage, and other problems

newer drum wheel cylinders have a spring in them that pushes the seal's out keeping them from leaking, so they do not need residual pressure, and can be used with a disk brake M/C, so when you do a conversion remember to always replace the rear wheel cylinders with new ones
