My guy does it Jim's way - everything on the rollers including
the very careful handbrake test.
I find it useful to see the balance when it's on the rollers so
you know everything is adjusted properly - you don't get any
balance figures with a tapley :(

I had one test where they had my rear wheels spinning in
opposite directions on the rollers...tester claimed it was some
sort of technological improvement or something.

well i have had a poke about under it & all seems well, no play
in the prop or diff & the handbrake works as normal so *touch
wood* no damage has been caused
i was rather shocked to see that he managed to get it to lockup
on the handbrake though!

On the rolling road, I doubt you have the same amount of kinetic
energy as you do when driving along, so it'd be much easier to
lock the wheels.
When you're driving along, you have the momentum of the whole
1.3+tonnes of the Landy to stop.
On the rolling road there's only the momentum of the rotating
wheels and rollers that you need to stop.
I suffered a total brake failure on my Series 1 (single line
brakes) almost four years ago, and I had to use the handbrake to
stop. I can report that the handbrake does work quite well for
this.
My new girl-friend at the time (who is now my wife) said she
more scared on the drive home when she knew I had no brakes than
at the time of the actual failure when she was merely puzzled as
to why I seemed to be reluctant to slow down and merge politely
with the traffic on the busy roundabout!
I can also report adrenaline is actually brown, as some leaked
out.
Cheers
James

There is a method, too long winded to write out because I can't
be arsed, and it works. I use it on every Series I test. Yeah,
both of 'em.

Not for the handbrake no, but for the footbrakes. The handbrake
is done on the carpark of my testing station, its on a hill so
easy.

Like I said, there's absolutely no need to use a decelerometer.
As for the parking brake test on a hill...... that doesn't sound
like it's a correct method of inspection.... well I suppose the
Tester must be comfortable with doint it wrong..... If VOSA send
him one down, and he does it the wrong way, he gets points.

So how do you do a brake test on a 90/110 (permanent 4wd whether
you like it or not) when you've only got a single axle rolling
road?

The place I go to does it on the single axle rollers. It's only
low speed, and there is a message in the cab saying it is ok up
to 10 km/hr.
