does my 83 944 n/a have the adjuster for brake pressure applied (ie:front vs: rear) and if so. where is it?

any help would be greatly appreciated.

 

No there isnt, but if you have a big difference in pressure you may need to check your master cylinder. Or the brake fluid may have some contamination

 

If this is a problem you may also need to check your calliper pots and slides for seezing as if this happens the fluid pressure to the seezed calliper can't move the pot, thus the pressure to the remaining callipers increases. So for example if one or even both your rear callipers have seezed the braking force will be vastly decreased or in extreme cases nun at all and all or most of the pressure gose to the front callipers which may be difficult to control the vehicle whilst heavy breaking.
In some more modern cars there is a stabliser valve or brake balance valve which in most early designs is a small steel ball type valve that can move formards and back in a chamber depending on momentom and G-force during braking restricting fluid to the rear wheels to prevent them from skidding as the wait of the vehicle is thron forward to the front wheels at the same time more brake pressure to the front wheels.

If you find any seezed callipers, I strongly recomend replacing them.

Sorry for the banter!
