Good point. There are lots of options on Amazon for go kart brakes. There are mechanical and hydraulic options. What size rotors are you using? Looks like 7” +/- are standard. The hydraulic would be great other than you would need longer brake lines.

Hello everyone, the problem with using bicycle parts is they are
simply not made to stop the weight of an aircraft. The calipers are
just not strong enough and will eventually fail the first time you
really need them, usually breaking off where they mount.
Bicycle braking systems are normally designed to pull up something
that is a maximum weight of 120 kg total. Braking something 3 or 4
times this weight is much more than what the system is designed for,
the rotor will build up so much heat that it will warp and the
fittings holding the brake caliper will eventually break.
You should be looking at systems for things like motor scooters.
Even though the weight of a motor scooter is not as much as an
aircraft they are continuously braking from fairly high speeds and
are more than strong enough for something like the X-Air. You will
see that the brake caliper itself is probably twice the weight
because it has a decent casting where it attaches to the frame and
also the disk itself will be 3 times thicker.
Experience shows that the bicycle system especially if you go
hydraulic works really well for things like engine run up at the
first time you need to brake in a real emergency may end up in
tears.
