mk2 braking

[jmk2g40]

Is it essential 2 hav a brake servo on a mk2 running a py lump using the following brake setup
Audi 256mm disks and pads Goodridge stainless brake hoses up front and stock drums on the rear?

Hav heard that you can use 2 master cylinders 1 for the front 1 for the back is this worth doing. remote servos seem a bit steep for the price.
