Further to the Wiz :
It is usually detailed in the MEL OPS proc for Main gear inop( Airbus) . It indicates that specific Perf has to be done . Also mentions "in case of engine failure case .
Doesn't seem to be any reference for the test pilots to just leave them hanging because they cooked the brakes or its a " hot " day . Never seen this considered even in a region where OAT's reach high 45+ degrees in the summer . If brakes hot " delay takeoff " . Seems clear from the manufacturer's viewpoint .
