Are they disc or drum or what? I'm about to change the breaks with my uncle and he wants to know.

 

all 240s are four wheel disk brakes. they used various brake vendors (Girling, ATE, others), sometimes several different types in the same year, so its important to know which calibers yours has before ordering pads, rotors. turbo models often have bigger front brakes, ABS were different than non-ABS, etc.
