I think they look pretty smart, and are clearly just copies of Brembo's, but would you risk it? Tough call I think, as your master cylinder is basically just a piston to push oil to your calipers, so there's not much to go wrong.
I'll open this one up to debate, some of the main cons will likely be:
- made from monkey metal
- replacement parts (lack of)
