hitch:
me thinks we need a braking thread
I think only mods and admin can ‘break a thread’ on this site 
TAXI !!
ROG:
I cannot expand on what I’ve already stated and had proven.There is no such thing as a right or wrong way if they are safe - just different ways of achieving the same safe objective - one way may have advantages that another does not have though.
I am not going to argue with the quiz answers or the above statement, but as a reasonably mature ■■■■, there are 2 reasons as to why I prefer the old methods.
While the engine is being used as extra braking, it is spinning faster which turns the compressor faster. a plentiful supply of compressed air is always welcome, especially when you need it.
The other reason I prefer using the gearbox to slow down is that it gives everything else time to catch up instead of screaming slip rings, it isn’t as though synchromesh boxes are new, they were used regularly in the late 60’s in HGV.
Although it was later proven to be maintenance related, the fatal crash in Sowerby Bridge may have had a different outcome if the truck was in a lower gear before the descent.

The method in the answer would NOT be used for such a situation - I did clearly state that the method used should depend on the circumstances at the time - there is no one-size-fits-all
- You are driving a fully laden 44 tonne artic (MANUAL GEARBOX) on a dual carriageway at 50mph in top gear. The very bad camber on the roundabout ahead dictates that you will need a low range gear to negotiate it.
What is the safest and most fuel-efficient way to slow down?
For general UK roads - ENGINE BRAKING AND IF NECESSARY EXHAUST AND/OR MAIN BRAKES - NO GEARING DOWN WITH CLUTCH DIPPED AS NECESSARY TO PREVENT STALLING — each situation to be judged by the actual circumstances at the time.
Hi Rog why press the clutch i was taught to use the exhaust brake for going down hill and the prob with putting you clutch down was the fact that in most trucks i have driven the exhaust brake was on the floor and you had to use your left leg and would be difficult to do both in the daf the exhaust brake is right next to the clutch and free rolling with your clutch down would give you less resistance in braking as the gears are not helping

Hi Rog why press the clutch
If slowing from top gear to a low range gear there will be a point where the clutch will need to be depressed a certain amount to stop the truck from stalling - no different than being in top gear in a car and coming to a stop or going to 1st gear.
no need to use the clutch until necessary
