First mot
Well I`ve joined the mot club it will be three years old on the 29 th

As a motor vehicle technician believe it or not we can mot our own vehicles with out question, However our works controllers policy is we will not be mot`ing our own vehicles but we can do each others, we have seven testers on site.

So on to the brake roller tester yes it can be done on a normal roller tester without damage to the transmission, two weeks later it`s driving ok nothing has broken, just make sure you put the transfer box in netural first.
I did the brake test as my shift mate who was testing it did not fully understand the transmission system, this is allowed under the mot rules.
As the test went on we had a good look round the car all is well but I was amazed at how quickly the pas pipes start to corrode, they have had a good greasing ( along with everything else ). Anyway the car passed the mot with one advisory, nail in n/s/r tyre, I would`ent mind but the tester did`ent see the nail.
I was pulling the stones out of the tread when I shouted over "it`s got a nail innit". Good that's an advisory for you then.
Censored I`am not even testing it and I`ve given my self an advisory on it`s first test. !!

If you have a limited slip diff fitted be careful as we did`ent realise the brake roller tester locks the none rotating wheel automatically, this may harm your nice expensive diff, may be one to ask the tester if you have one fitted.

Any doubt use a tapley meter, Excuse the spelling I`am better with spanners and wires.

why bother to put transfer box in neutral , that only disconnects drive to main gearbox not axle from axle ?

Granted it might be overkill, but I would rather be on the safe side than picking up bits of gearbox, or something going wrong.

Also don`t forget this is a public forum, a little knowledge in the wrong hands can be a bad thing,
There`s a lot of people who take what is written in or on internet fourms as gospel, we`ve met these people once apon a long time ago we used to call it pub talk.

How many customers / owner / operaters, have came in with forum print outs demanding we carry out the following works. I know I`ve had a few.
It saves us getting sued in the long run Excuse the spelling I`am better with spanners and wires.

yes agree , best on safe side you never know if some got a special diff (locker or lsd ) fitted
most places tend to use the tapley meter now to be on safe side when doing 4x4's

yes use neutral

or your end up with someone saying you damaged my gearbox or something !

The place I have been takeing my Landrovers since 1987 always uses the digital equivalent of the Tapley meter and will not test 4WDs on the rollers.

If you have either axle LSDs or ATBs, and/or an ATB in the centre diff, don't test it on the rollers. Also make sure that the tester knows not to yanks the handbrake on when moving!

Best bet is not to test any fulltime 4WD on the rollers at all IMHO.

The place I take mine to has a special four piece floor that they just drive vehicle over and apply brakes. Never seen this before, and was amazed as it just looks like normal floor. But that's made me always go there since.

This/\/\/\why risk it,if you have any problems later you could never be certain it wasn't caused by the brake test.Oh, congratulations on it's first pass,you must be very proud Mr. Green . Pov.spec,ftw. 2006, 110,TD5.

Landy andy,

Its called a plate brake tester the most dangerous bit of kit I`ve ever seen in a work shop, I saw a guy use one once, myself I`ve only seen one.

Mk4 ford escort, drove on to it or rather at it braked hard it did`ent stop, the car hit a wall and that was the end of that mot, possible head lamp aim issue !!
Give me a rolling road anyday

I`am glad it passed just annoyed that me and my big mouth ended up giving it an advisory on it`s first test, I wanted flying colours on it`s first go, slightly dented pride. Excuse the spelling I`am better with spanners and wires.

I thought it was great. I could not stand the normal test with a Tapley meter and numb nuts doing 30mph, then suddenly applies your xbrake Big Cry Big Cry

pulling handbrake at 30 is ridiculous

My preferred test centre use a brake roller that contrarotates the wheels thus allowing safe testing. Very clever kit. Rhubarb and custard let fly with their secret weapon.

If you think they're that incompetent, go somewhere else!

I always remind them that I have full-time 4WD, LSDs, and a transmission handbrake that mustn't be applied when moving. They never mind a polite reminder.

Also, you can still insist on driving your own vehicle for the MOT if you are particularly worried. Although principally intended for vehicles which have unusual controls (modified vehicles for handicapped drivers, vintage vehicles with a the accelerator in the centre, that sort of thing), it is still as far as I know your right to insist that only you drive.

A good few years ago I used to own a 4.1/4 litre Derby Bentley, sadly long since sold. That was always interesting at MoT time since the front brakes were driven by a mechanical servo on the gearbox, which meant that if the rear wheels were not rotating the front brakes didn't work at all. It could only be tested with a Tapley meter and I cannot ever remember the MoT tester even suggesting that he should drive - they always insisted that I drove throughout the test. Mind you most people who haven't regularly driven a car of that era can't work out how to get in without the gear lever going up their trouser leg!
