Question Does MOT include road test?

The reason I ask is that I seem to remember that last year they took my car for a 'road test' after all the other inspections. Is this part of the MOT or were they just going for a joy-ride?

I think you'll find it can be fatscoobyfella...........

If the testing station owns 2wd brake test rollers, they can at thier discression take a declerometer (sp*) out with them on the road to test the braking efficiency of the test vehicle.
This is done for permenant 4WD vehicles..

Not usually part of the MOT test, unless they can't use the rollers to test your brakes, if you have full time 4WD for example, then they drive it up the road and use a guage in the car so it might not be as bad as you think, not all garages are out to rape you!

If you have a four wheel drive car then its definately part of the test because you cant use a single axle brake tester; the MOT tester will use a Tap. meter which measures decelerative force.

I remember the good old days of the Tapley decelerometer when I used to be an MOT tester / technician, heres a link to the Tapley web site just so you have an idea of what one is and how they work

http://www.pwds.co.uk/tapley/products.htm

The most common ones are in pictures 1,2 & 3

Hopefully helps a little to explain why they are out and about in your beloved scoob perfoming emergency stops .

Thanks for the advice. That explains why they asked me if the car was 4WD.

I've just had Pagid 4-2-1 Black break pads and braided hoses fitted so I better warn them to wear a seat belt when they test them!

Wouldn't matter....they'll be cold when they test them

They'll still pass though, you could cut a hole in the foot well and use your feet to stop and it'll still pull enough G to pass As my mate tragically found when his scoob fitted with FR pads passed the MOT, but drove into the back of an Audi the next day because his pads were cold

Record stands at 99% efficiency by my Land Rover. Nothing else has come close (mainly due to the off road tyres having having such ferocious bite in the dry)

Having Pete in the car would adversely affect the braking performance too!

Would you belive there are owners of £100K+ Ferarris and Astons etc that dump their car at a testing station in full trust of the owners and its emplyees?

Disgusting!! I mean, it's just asking for it to be doughnutted on the car parks and taken for a blast up the bypass

The only reason they can road test the car is for the Tapley meter brake test, and if you have a Scooby you should insist that they do since testing on the rollers is very bad for the centre diff.

What about cars with DCCD? Would it be OK in open position?

No, if it's permanent 4wd open diff or not it doesn't go on 2wd rollers...it is catorgrically printed in the Tester's manual

Also Limited slip differentials cannot be tested on rollers...scoobs have one on the rear.

And also CVT transmissions.

What about RWD? the majority of the braking would still be on the front wheels Id guess where as its driven from the back so would that need to be road tested? my RX7 is due this week and Im tempted to set my PFC so the car wont rev past 3.5k rpm...LMAO

If it has a rear LSD then it will be road tested. As overall braking effort is worked out between both front AND rear axles.

Although there is no harm putting the front wheels on the rollers on a RWD car. But it will not be done as part of an MOT test if the driven axle has a limited slip diff.

That'd be a difficult choice for the MOT tester; measure the decelerative force; or beat Pete to death with the Tapley meter..........
