Brake test rollers...damage?

Here in the UK we have an annual m.o.t test (to check the car for road worthiness)......they use rollers that drive the wheels to test the brakes,the front first and then the rear.....is this ok to do with the RAV4 with All Wheel Drive or could damage be done...just curious.

4WD cars cannot be tested that way. It damages the drive train. That also is a VERY old system to test brakes and not very reliable too.

Depends entirely on how the rollers are set up. We had such at test in CT for a short time a few years ago. It didn't damage any vehicles I know of and was very revealing as to brake balance and effectiveness. Was a hard test to pass but meant the brakes worked well.

Come to think of it I don't remember it using rollers. They drove the car onto a platform and hit the brakes.

We've "progressed" from that to no safety inspection at all.
Just emissions every two years.

It's the pedal (or the handgrip) on the right!!

Funny, i remember reading a notation from Toyota that brakes should not be tested with only rear or front end on rollers due to high stress levels on the drivetrain with 4WD cars.
Where i read it i can't recall, but i am fairly sure reading it.
