MoT - Rollers for brake test
I can't find the topic on here, but I'm certain that I read a while ago that it's necessary for our cars to have their brakes tested with rollers under all four wheels rather than just the fronts or rears during the MoT, to avoid potential damage to the differentials and gearbox.
Can anyone confirm if that's correct please, as my (DCCD) 2005MY Blob's MoT is due in a two weeks and my local garage only have the one set of rollers. They seem to think it's okay, but I don't want to find out the hard way that they're wrong.
Thanks for any replies.

They are wrong, for any 4 wheel drive vehicles i test i use the decelerometer and go on road test. Thats the right way to do it
You cant put 4 wheel drive on 2 wheel drive rollers, some will say you can do 1 wheel at a time but i'd rather do it properly tbh.
You can always bring the car to me to test for ya i'm based in brum and the mot's are £30

gazza is spot on it will cause sever damage to diif and transfer box,
any test station with a standard brake roller (single axle roller) can still test 4wd and awd as they also need to have as per vosa standards a decelerometer for a on road brake test.

As advised in no circumstances let them put your scooby on a set of rollers a decelorometer is what they need to use and road test.. Not sure in the uk but in Sweden we don't even need to let them drive the car but do the test with them in the passenger seat.

I spoke to a guy at a Subaru garage who motd mine and he said that for how long they're on there for its no biggy. I double questioned him do decelorometer was used on road

Check this thread out. I have had mine done on a two wheel brake test and was assured it was fine. In actual fact the wheels are only turned at low speeds for a short amount of time.

i bellieve thats just the one wheel at a time option, i have that on my rollers but i'd still rather do it properly and not take any chances with someone else's car, it's not so much an issue if the motors your own but i can't be repairing anyone else's motor when i dont get that much time to finish my own.

Had mine done yesterday. Terry who done mine asked if mine was perm 4wd. I told him yea its perm 4 wheel drive. He chucked the meter in and took it for a spin. All good on the braking side of things especially as he admitted he had to anchor up hard as some plank pulled out in front of him

So brun, your an mot tester and a mechanic are you, take it you have done a few of these with your vast experience giving you the ability to mock and suggest that I'm wrong.

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.

I'm sorry, but some of you seriously worry about breaking an Impreza transmission during an MOT test?

As suggested earlier in the thread, read this and pay particular attention to Alan Jeffery's comments and then decide if my comment was correct or not
.................and yes - you are wrong..................
