Disc brakes are now used on many modern trucks, led by the European manufacturers Volvo, Scania, Daf, Leyland and Mercedes. The technology lag in employing air brake systems with large disc brakes has now caught up. In the next year or two you will see many more heavy trucks being made with disc brakes.
They are, they just haven't caught on in the US as quickly, but, as the stopping distance requirements become more strict, they'll become more commonplace. Peterbilt and Kenworth use discs as standard on their steer axles. The biggest drawback - particularly for fleets which hire inexperienced drivers - is going to be maintenance. Replacing the pads is easy, both on the Bendix and Wabco systems, but, if a driver burns their brakes up coming down a mountain grade, a six around brake job with S-cams can be done in three hours, replacing both shoes and drums... it takes significantly longer if you have to replace rotors on an air disc system, because the rotors are bolted to the hub, meaning you need to remove the entire hub to get to them.
By the way, the companies which innovated air disc brakes weren't truck manufacturers - none of them ever offered a proprietary system. It was Bendix and Wabco who did.

Why might heavy lorries need eight rear wheels?
In a heavy truck, each wheel has to support large road and the pressure on the road due to each wheel is large. Since, pressure = force/area Using of extra wheels reduces the pressure on road due to each wheel. This prevents the wheel from causing damage to the road as well as sinking into soft ground. This is why, extra wheels are used in heavy vehicles.

No, they are inferior to disc brakes. Drum brakes were used from the beginning of the auto up until the late 60s. Drum brakes are more prone to overheating than disc brakes. Disc brakes also shed water much better than drum brakes which improves stopping distance in wet conditions. Disc brakes apply pressure more evenly than drum brakes thus improving stopping distance. Disc brakes are superior in every way.
