This is a silly question but its something I need to know, the MOT on my scoob is due but do I take it to a special place to get it MOT'd as it 4WD, my local MOT place tests the brakes by putting the front wheels on rollers then the back wheels, I checked in the manual and it says that you cant have the front wheels or back wheels running independantly of the other two i.e. it cant be put on a toe truck or put on rollers. Do I take it to this place but jack up the back wheels while he tests the front brakes?
(I told you it was a silly question)

They need to do a short road test of the car if they don't have FWD rollers.

i think they use a taplow meter whilst doing above

There was a a long thread on this about month or so ago started by pslewis. Got quite involved.
My tester uses the Taplow and I drive.

Yes, do be careful. I had to take my car to a local garage and watched them like a hawk! The bloke couldn't even deactivate the std alarm FFS!! They wanted to test the car on the brake rollers at which point I said: "It's a permanent 4wd car, you can't test it on 2wd rollers!"

They're response was, "why"

Unbeliveable!

Then they only wanted to take the car out by themsevlves for a road test....

That wasn't about to happen!

My advice, take it to a specialist...I wanted to take mine to Xtreme, who refer to a local Scooby friendly garage, unfortunately, I just couldn't find a convenient time before the MOT ran out. Will book extra early next time!

Just to re-iterate the above: Do not let them brake test it on a single set of rollers. It will cause diff wind up and potential damage.

http://www.motuk.co.uk/manual_370.htm

"Certain vehicles should not be tested on a roller brake tester, eg vehicles with
More than one driving axle permanently engaged
Limited-slip differential
Belt-driven transmission
Brakes for which the servo operates only when the vehicle is moving
These vehicles should be tested using a properly calibrated and maintained decelerometer or a plate brake tester designated as acceptable for the statutory tests, see Sub Section 3.7 B, page 25, and C, page 26.
A roller brake test is also not appropriate for vehicles with damaged, under-inflated or studded tyres."

The road test with the meter should be short, my tester just used their car park, they only need to get to 20 mph.

Although it's been asked and featured on this page 1000's of times beforehand, so it has been well covered and debated.
