Technical warning!!!
Brakes convert kinetic energy in to heat energy. If the braking surface is too small they will overheat. Also, if they cannot lose the heat quickly enough they will overheat. Once a braking system overheats you will get brake fade which is a loss of braking efficiency.
To improve the braking system on any car you need to improve any or all of these areas.
Vented, drilled, grooved discs are all methods of dissipating the heat more effectively, but they only become useful once the limits of a standard system have been reached. If you don't plan to reach those limits they are a waste of money.
I tend to agree with those that recommend ensuring the standard system is 100% as a starting point, the braided hoses will help with this.
Starting with the non servo system allows you two upgrades from other Pandas...
1. Fit the servo system from a 4x4, clx etc.
2. Fit the system from a Selecta, if you can find one. Because the later Selecta's had the 1108cc engine and of course, no engine braking, they had the best braking system of any standard Panda. This was achieved by larger front discs, calipers and pads and larger rear wheel cyls. You must use the master cyl. and servo too as they supply more brake fluid to these larger items.
I did warn you.
