I replaced clutches and brakes in my 450 dozer. Now when it comes to adjusting the brakes. When the manual says tighten the brake band nut down all the way first.does this mean till I cant turn the bolt anymore or till it feels kinda snug?

You need to be tight enough to take all the slack out of the linkage and band. It is assumed you freed up any stuck pins and have the threaded parts turning freely. I tighten until there is a definite resistance, but not a hard force, to turning when the screw tab comes up out of the detent the 1/4 turn called for in the manual.

To work right, every step for adjusting the steering and brakes must be done. They must be done in the order shown in the manual. Both sides must be done for the system to be in balance.

Did you replace both the steel and lining discs? Did you measure the thickness of each of the steel discs and lining discs to see if they were at spec? Not knowing where you got your parts there are discs sold out there that are the wrong thickness and can cause the clutch not to dis-engage if they are too thick.

Don't just see that the clutches move. All the adjustments need to be checked and made if not what the manual calls for.

Did you replace the steel discs? If so how thick were they? 450s use thinner steel discs than 450Bs and can make the clutches drag if used in a 450.
