I am intereested in buying 1st generation vitz, I heared that vitz brake have issues while AC is on...? Brakes will not work at high speed if AC is on. Is this true...? Any idea.

I don't think there is any relation between AC and brakes.

Brakes work in any case in Vitz 1st Gen, they are just not boosted by Brake booster. And that also happens when your car and its pipes or vacuum gets weak. This happens only in stop and go rush; when AC is on, the pedal gets hard. This doesn't happen always as car relearns the new settings and increases the RPM to compensate. And there is always reserve vacuum in car so while its running there is no issue.

Ever applied brakes after the car has been turned off?, the first 2 or 3 pedals works as intended.

To avoid this issue keep ur car well tuned (quality plugs, air filter, clean throttle body and working idle air control valve).

Means there is no issue with brakes if I keep the car well tunned and in a good condition...?

Yes if ur brake booster and cylinder are flawless.
