The car is due MoT tomorrow and I've read a lot about putting an AWD/4WD on a two wheel rolling road. But is it ok to do brake checks on the two wheel system or should I insist they do on the road?

Thanks in advance
Cheers

Do not let them put the car on the 2wd brake rollers, unless you want a broken centre diff!
They should take it on the road and use a meter to measure braking force (I forget its name)

It is called a Tapley meter (or used to be called it anyway), I had my brake test carried out on the road by the VOSA tester.

Just found this ....

Vehicles not to be tested on a roller brake tester

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.

Well done mate

The tester even commented on the good condition of the car which was encouraging

My vars brakes have always been done on the rollers apart from once when the rollers were broken. No issues at all. This is assuming the MOT tester knows what he is doing. My MOT tester has rallied Impreza's for years.

As already said, A scoob should never be tested on the rollers, always done on the road.

It always makes me chuckle knowing he has just had to unpeel his face off the windscreen with the brake and tyre set up I have

Saying that though if you watch the speed on the rollers, you can walk faster than it moves at
