atl advice and presented weight etc

The brake weight for class 4 is provided by the brake rollers on a ATL
Non ATL brake weight is found on brake test weight charts or comp 2

Performing mot"s on ATL is not that much different to 2 man testing ,it's just the assistant that is normally used has been replaced with the shaker plates and a few modifications regards brake pedal applicator and mirrors to check lighting.
If you feel that for some reason you need to use an assistant then do so you won't get into trouble,for example you will need to use an assistant to turn the steering wheel lock to lock while your underneath checking components,where vehicles have remote servo ,ie Peugeot you need to check the linkage from brake pedal to servo,so you may need someone to operate the brake pedal while you check components if and where visible .
Use the brake applicator to apply the service brake with engine running and engine off
The shaker plates operate in 2 modes,one is a side to side motion for checking the suspension and rotational mode for checking the steering system ,you might find it benifical to read the relevant sections regards the steering and suspension sections in the manual to get yourself familier regards the methods used as they are quite specific to the different types of suspension set up,for example you would not use the side to side mode to check a suspension set up that has King pins,you can now see why it's important to familierise yourself with the methods of inspection.
The brake rollers will be computerised and you will need to follow the on screen prompts and then you will be given a print out.
It takes time to find a good routine and get used to ATL but the more your do the more competent you will become,plus there should be someone at the test station that will guide you,just remember to conduct the test the way you do now ,the procedure and elements are the same you just use devices to help with the test instead of shouting or telling someone what to do.
Try not to fall into the habit of of trying to combine all parts of ATL test and 2 man test,in other words use the shaker plates and then use an assistant to rock the wheels on turn plates etc etc.
The shaker plates also comes in handy using the side to side mode when checking the rear suspension.
With the regards to pinch bar and heel bar will still to be used for certain aspects of the test.
If there's any thing more I will add for you but I need to watch marchella itv just now .

Little to add really except I have been using ATL for about 7 year's now & wouldn't be happy going back to manual testing regularly.

Correct me if I am mistaken but as far as I'm aware there is no requirement to retain Brake test results. I always do as is best practice and retain copies of all documentation

The Information column in Roller Brake Testing section of the Manual states that the brake test results should be printed out but I haven't found any specific reference to how long the records should be kept. Common sense says 3 months in line with emissions print outs as this is the maximum time period for an appeal.

thanks very much guys for your help

I have an atl bay, but do the brakes in manual mode. Nothing wrong with doing it that way.
