Jellybean Posted October 13, 2018 Share Posted October 13, 2018 Hey Got the NCT today (MOT here) , They cannot put the car on the rollers to test the handbrake as she has an LSD Decelerometer Test 4. If the vehicle is of a type which cannot be tested on the roller brake tester, it should be subject to a decelerometer test as follows: • With the vehicle on a reasonably level road, place the decelerometer on the floor of the vehicle. Follow the manufacturer’s instructions and set it in the zero position. • Drive the vehicle at a speed of approximately 32km/h (20mph). Apply the parking brake and note the reading on the decelerometer. What happened To test the handbrake, he took the car to the small confined carpark and locked the rear via the handbrake, skidded her down the wet concrete decline between customer cars for 5 metres! easily cause damage and stretch the handbrake cable I was livid!

Definate wear inside the discs. And slight tension on the cables. They wont get damaged that much. But i got some new cables if you need Quote Link to comment Share on other sites More sharing options...

No issues with mine and in my ownership my second UK car was tested on the rollers the same way on 13 mot tests, same with the first UK car i had My thoughts are exactly the same. If the car`s transmission is in neutral, how in the earth does it effect to the differential if both rear tyres roll with the equalent speed? My car has had 15 MOT test during my ownership and I never have had any issues at all. Quote Link to comment Share on other sites More sharing options...

My car has had 15 MOT test during my ownership and I never have had any issues at all. Car does be in gear it's driven on rollers it's not in neutral. I don't know if it would damage the diff, maybe someone on here more technical. Quote Link to comment Share on other sites More sharing options...

nigelboyne Posted October 16, 2018 Share Posted October 16, 2018 Cars driven onto the rollers then put into neutral test the brake then into gear and drive out the roller Over here they test front rear brakes on same rollers as they do the handbrake, the car is defo in gear for part of the brake test, anyway I can't see that test doing damage to the diff but maybe it's better be safe then sorry.

Ric Posted October 16, 2018 Share Posted October 16, 2018 It would only be in gear if they don't have powered rollers and need the engine to move them. Nearly every MOT i've been to their rollers are powered and car is neutral. Quote Link to comment Share on other sites More sharing options...
Dnk Posted October 16, 2018 Share Posted October 16, 2018 (edited) How would they do the front wheels or a vehicles non driven wheels if they weren't powered rollers ? Edited October 16, 2018 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
PJJ Posted October 16, 2018 Share Posted October 16, 2018 How would they do the front wheels or a vehicles non driven wheels if they weren't powered rollers ? Agree with what Dunk says here, majority of our cars over here are front wheel drive. Therefore how would they test the handbrake on rollers if they weren't powered ones? Reading this though out of curiosity I'm going to check with my MOT testers how they test my handbrake. But it didn't leave the workshop during the test whilst I was waiting in reception so it wasn't done on the road. Quote Link to comment Share on other sites More sharing options...
jjs_82 Posted October 28, 2018 Share Posted October 28, 2018 OK so I was in for my nct yesterday and for the first time they put her on the rollers. I told them she had a LSD and he just looked at me and said so. So after the test he tried to tell me my car did not come with recaro seats and I would need to get a engineer's report for aftermarket seats.

Jellybean Posted October 28, 2018 Author Share Posted October 28, 2018 Alot of A-holes work in the centres , with zero customer training ; it does state in the NCT manual a car with an lsd should under go the Decelerometer Test not the rollers I have Recaro's in mine (non Factory) , they said nothing ; shows how inconsistent the test is - - - Updated - - - Alot of A-holes work in the centres , with zero customer training ; it does state in the NCT manual a car with an lsd should under go the Decelerometer Test not the rollers I have Recaro's in mine (non Factory) , they said nothing ; shows how inconsistent the test is Quote Link to comment Share on other sites More sharing options...
