Next question, here now: Girling brakes

[Hurvinek]

Since I will be driving my newly acquired van over hilly routes and also in city traffic on friday afternoons, I am thinking about improving the brakes. Does anyone have experience with the cast iron Girling brake drums? Is such a conversion recommended or should you rather keep your hands off it?

If you install them, what other components need to be replaced? And is there anything special to consider during installation?

Thank you very much in advance.
