Print the Yellow first, then the gray, then the red, then the black -- OR
-- print the red in several thin layers AND add a small amount of glue
(hide glue) to your color -- this will make the color more fast, but may
make subsequent over-printings more difficult, as the glue behaves like
additional sizing and makes the paper less affectionate to pigment. -- OR
-- be prepared to frequently change (or clean) printing brush (and perhaps
the block as well)...

You didn't describe the pigments you are using or their preparation -- that
might be helpful in finding a solution... Use sumi in place of black
water-color. Or mix dry black pigment into rice-paste or use rice-paste
and pigment dispersion... The rice-paste not only makes a terrific
vehicle, it also is an effective retarder. For six or seven years I used
only prepared watercolors in tubes for hanga pigment -- now I use a double
boiler to cook up rice-paste (from rice starch -- four level teaspoons in
1/2 cup of water heated until completely thickened -- about 5 minutes -- in
double boiler) and mix dry pigment directly into the paste with reasonable
ease -- or first mix the pigment into alcohol and then into paste -- then I
use the paste/pigment mixture in dabs directly onto the block with
additional paste and water to taste. MUCH more control and MUCH
cheaper! I also use pigment dispersions sometimes -- adding directly to
paste, to make concentrated color for printing -- but I don't have as much
control, as I don't know what besides pigment is in the dispersions nor
exactly how (other than experience) they will behave.

Well the 'black brush' is the most effective solution. But I wash my
brushes a bit differently -- when I wash them, that is... I actually rinse
them, saturating them and rubbing two brushes together, then SHAKEing the
water out of them with a hard flick of the wrist/arm and then repeating
until the water SHAKEn out is clear. Otherwise, the pigment seems to stay
in there 'forever' -- the shakeing seems to allow more rinsing action amid
the very think hairs of my maru-bake.
