The disc brakes on the B310/ Sunny/ 210 were designed to handle a car of 1985 Lb [900 Kg Sunny Sport Wagon] but if used in a 1200 coupe that weighs 1520 Lb [691 Kg] then brake performance is improved substantially for that reason alone. The maximim legal speed here is usually 110Kph [68mph] so this brake setup should prove more than adequate in the majority of cases in an A series powered car. Fitting a Lancer power booster will further enhance brake performance if this is felt to be necessary.

Other cars with more powerfull engines & higher performance can still use the B310 strut, but with better brakes as these are not hard to adapt. Even the bigger, local Commodore caliper just bolts right on.

get the brakes off a pintara or trx or whatever theyre called....
i got 4 of em on my ute and it pulls up a treat....

In SA you can put in a A14 without changing brakes but it is a good idea.

It all really comes down to what you want to spend.

the residual pressure check valve is it located at the bottom of the resovior? and you just remove it hey?

To be a litte more specific, but still being too lazy to link to the threads, I remember talk about S13 calipers and rotors on a 120Y strut, which is some pretty serious braking power - well above that offered by a set of girlocks on the Stanza strut - meaning maybe it's possible to get a whole lot of braking power out of a 120Y strut....which would mean top brakes and lower unsprung weight!

More think out aloud than actually presenting a well researched point....
