I bought Dia compe MX 2 v’s and levers.
Stock pads where ok, but once worn i switched over to a set of Aztec cartridge pads.
Being stiffer units the difference in braking performance was a drastic improvement.
If your brakes don’t have cartridge pads, then a good set will improve things and be cheaper than a new brakeset.
Faff to set up, but once dialled in, swapping out pads is a doddle, remove split pin, push out worn pad from cartridge, clean cartridge with old toothbrush, push in new pads and off you go
