brake testing a range rover

[henryandlesley]

Hi how should an mot station should test the brakes should they use their meter and test on the road or put them on a rolling road

[POTASH]

just had mine motd and he drove it up the road with a meter to test my brakes

[thermidorthelobster]

My 4wd vehicles have all been done on rolling roads, the 6wd was done by driving off with a meter and slamming on the brakes.

Rolling road will only go 3 or 4 mph which SHOULD be taken up by the centre diff. so in theory  OK
The decelerometer can be placed on the passenger side floor and driven down the roadthen hit the brakes. The tester will notice any pull to either side to indicate an imbalance
Mine was taken around the back on a large gravel car park, he floored it then hit the brakes, locking all 4 wheels, came back a little embarrased and said ' **** me, that thing can stop' then told me he had only tested series landies before  :lol:

I specifically asked them NOT to use the rolling road cause I was worried, previous MOT was done on rolling road and all was OK but he had done a few 4x4's so knew what he was doing. but he was too busy

i got told the same with my rangy not to go on rolling road but whengot to station they did not have one when i asked how he was going to tes he watch and see as the test went on he drove back out of station came racing in hit the brakes and a screen in front of were he hit the bracks came up with results got out and said yep they look and feel fine good job they were  :lol:

I have been told that it sould not go on it as it is in 4wd all the time

Dont know about the Jeep but mine is an '87 V8 Auto and was fine last year.  Just to check after I jacked up the wheel to see if it had 'wind-up' and nothing  :D  Its OK if the tester knows what they are doing.

If in doubt ring tester and ask if they done rangeys before and if they are willing to do the alt. test

[Range Rover Blues]

If the Range Rovr has the later Borg-Warner type T-Box then it should not be tested on a rolling road without taking 'precautions', the is a sticker to this effect inside the cab on some cars and a note in the manual.

THE MOT have circulated an instyruction within recent months that 4x4 should no longer be tetsed on rolling roads following some accidents, so the decelerometers that were going to be phased out are now back in vogue.

The tester simply has to satisfy himself that the brakes function correctly

[Dave Rogers]

As far as I am aware, no 4x4 with a central diff should be tested on a rolling road unless all 4 sets of rollers are driven and linked. The brake test should be done using a free standing meter with the tester driving the vehicle. The MOT only calls for the proving that the brakes stop the vehicle in a safe way without moving to the left or right.
You can specify the type of brake test, if the tester won't do it, then go someplace else, you're the customer after all!
