Yes mate there inside the drums, or thats the proper way todo it really. Adjust them, put the drum on, adjust a bit more, put the drum on, keep doing this till theres just contact between the shoes and the drum. Put the drums on, tighten the hubnut, go underneath, remove the heatshield and you'll see the 2 cables go into 1 cable, and a 13mm Nut, adjust till your happy. Bit of a **** to get on without a ramp.
Or, the cheating way, just remove the heatshield underneath the car, and tighten the 13mm nut till happy.
