hi
are you going to present the e-mail to the testing station or appeal the failure ?

Hi all,
Many thanks for your feedback,
I have had an email from the MOT Standards Team at VOSA and they've said based on my explanation my car shouldn't have failed on no reserve travel as the tester should not be yanking on my handbrake, he should be applying it in the normal way and then checking for reserve travel, which mine had if it wasn't yanked on as if you were trying to pull it through the roof of the car.
Maybe I explained wrong in my previous posts and that's why you said it should fail too, but it worried me because there is another tester in the area I live in, that agrees with my original tester that for the MOT the tester should pull on the handbrake as hard as they possibly can to check for reserve travel, but VOSA are very clear that you do not do this as it could cause unnecessary damage to the cables and pads/shoes.
The main problem I can see with pulling the handbrake on as hard as you can is if you get someone who is very strong then every car will fail on this, plus the handbrake cable will be stretched, but if you get a tester that is not very strong then all their cars handbrakes will pass. I find it difficult to comprehend that the rules surrounding MOT's could be so vague and so easy to manipulate to get an unfair failure, I personally feel there should be clearer guidelines on this matter for both customers and testers.
Thanks again for your perspective on this matter.
Kindest regards

hi judwud
even though you couldn't pull your hand brake to the top as you said, if the tester could than it is a fail. you can appeal but for a realitively simple fix i would live with the outcome of the test. if you have drum brakes at the rear, check the brake shoes for wear, if they are very low fit new shoes and readjust handbrake cable,also check automatic shoe adjusters (if fitted). if this does not fully sort the problem then you may have a stretched cable. hope this helps.

Hi Judwud.
What you have inferred is incorrect.
If the handbrake lever can be pulled to its "Stop"
then the vehicle fails.
This part of the test is not linked in any way to the roller brake test.
Your car has failed its test as there is no reserve travel when the handbrake lever is pulled on through its full range of travel.
I agree the brakes are locking before this point but thats not what this part of the test is about!
Hope this helps.
PS. Don't be tempted to Adjust/tighten the cable to solve this problem!
PPS. What make/model is your car?Last edited on Tue Feb 23rd, 2010 06:22 pm by KevG

Thank you bimmer, so why would it fail? This is what I don't understand, I could not pull my handbrake in the normal way and get it to the top, granted I could if I yanked on it really hard and pulled it on really fast, but surely this is not going to do anyone's handbrake any good. If the handbrake meets the minimum requirements well before the handbrake lever gets anywhere near the top then is it still a failure?
I understand that if it has to be pulled up to the top to lock the rollers up it will fail on no reserve travel, but if it locks the rollers on just 4 clicks and the handbrake will go up 8 clicks then I would have thought the remaining 4 clicks would be the reserve travel, am I wrong in thinking this?

hi
welcome to the forum. the roller brake tester ( RBT ) measures the performance of the parking brake, insufficiant reserve travel is the mechanical condition of the parking brake, even if it locks the wheels it can still fail on no reserve travel.

Hello all,
I have just had my car MOT'd and it failed on the above. My handbrake worked perfectly well, i.e it locked up the rollers after pulling it on 4-5 clicks, the garage said there was not a problem with the handbrake, it worked fine, but because the tester could pull the handbrake up quite far it failed for having no reserve travel.
I argued saying if it works after pulling it on 4-5 clicks then what is left is the reserve travel, the garage owner said no, if the tester can pull it up to the top then it automatically fails, no matter how well the handbrake works, or how many clicks it takes to meet the minimum braking requirement. Is this true?
Thank you in advance, any advice is gratefully received.
Sorry, I've put this in the wrong place
