Quote:The 1200 coupe CAME with disc brakes from new. They weren't particularly big or powerfull, but they were a good design & worked well.

The drums were good too, as long as they were kept in a serviceable condition & properly adjusted, they will perform quite adequately for many years.
I retained the drums on my '68 1000 sedan & drove it with a tweaked 1200 GX engine & five speed for the most part of two decades.
They worked just fine for me.
