NCT test results

kuro2k

I checked back on a NCT test I took in 2005 to compare the results with a recent test and I'm just wondering if someone could help me understand the results



2005





2013







Is it possible to tell from the results what the actual problem is?

Ok the Side Slip/Allignment Test (front axle) would be solved by getting the 4 wheels aligned but what about the others


Suspension (nearside/offside imbalance on the front and rear axle)
Test Brake Test (brake effort, ovality imbalance, front & rear axle)

Thanks

Where's the problem? You passed.
Brake ovality is down to wear of the braking components.
Side-slip could be Tracking, Ball-joints, Bushings etc.(But not always solved by getting the Tracking done).
Brake effort is possibly down to slightly glazed shoes/discs, but still a pass....

edit; your smoke readings have improved dramatically....did you use any additives before the test ?

Its a 96 and with a yearly test I would prefer to spread the cost of sorting any issues over the next 12 months rather than leaving it to the last moment

I got the terraclean treatment last October and started using dipetane on each fill around the same time

None of the results are close to a fail, so why worry.
If you want you could put aside a few quid every week to cover the cost of repairing any future fails.
But, there is not much point in spending money that you don't need to spend....wait for the next NCT test and see if you need to get any work done then.

Other then the slip test, nothing is close to a fail so I wouldn't worry too much.

Excellent results for a 96 car, the suspension test is just showing signs of wear and tear. There is more suspension travel now then in 05 so the shocks and/or springs are getting a bit soggy.

Whats with the brake test results from 05 though? No readings on anything.

Thanks ND,

Front shocks and springs were changed last summer, rear shock and springs are original.

I presumed the brake system was 100% back in 05, I got the same results again in 2008, zero readings.

I guess I would like to just keep everything in perfect condition.

is the car four wheel drive is that why there no brake results

Its a 96 Toyota Hilux Surf, (part-time/selective 4x4) so rear wheel drive for the test. It has a LSD, I'm not sure that makes a difference, afaik they fail after 100k and I'm on 240k so it probably isn't a issue. In 2011 the results stated the front axle imbalance was 10% and rear was 0%

It seems to be going in the wrong direction so I will probably have to do something before next years test so it would be great to know what would cause the imbalance

TBH its the first time I've looked back on the tests, results seem to be all over the place, I haven't replaced anything except the front shocks and springs in 2012

Maybe it is a good idea to make new thread with other people results, and what they needed for retest. Might be interesting to see what people fail on, and how our old cars do...we could calculate the pass rate for boards.ie motors forum???

I think this would be a great idea, NCT/GOV/RSA like to scare people into thinking anything over 10 year old is fit for the scrap yard and it couldn't be further from the truth..

Yeah once it passes I wouldn't worry too much. My brake effort changed before after a cleaned a brake pipe. Never even took it off. Same with suspension. Just changed one part that was gone and it came back different.

Not sure if it actually changed or just some mess up. Have a look under your car and see what is wrong with it. Something can go on the way home from nct after passing.

they shouldn't have do brake test rear axle when there lsd fitted. could have damage it

They didn't (haven't)- according to OP.

Sorry but I never stated a brake test never took place, I wasn't present for the test in 05 but I was present at the others and a brake test definitely took place at every test since 08

OP it's great that you care and that you want to have your car in perfect shape.

But NCT results might not always be accurate, as their equipment might not be properly calibrated.

I had an issue once, when just after sorting out my brakes and having perfect results for them, NCT test showed imbalance of over 25% (below 30% so it passed).
1 week before those brakes had no imbalance at all.
And what's even more convincing is that imbalance it was left side stronger than right side, in all three tests (front brakes, rear brakes, parking brake).
IMHO it clearly indicates that their equipment was not properly calibrated.


IN relation to your 2013 results.
Do you feel car pulling to the left when you brake severely (without ABS kicking in) ???
With 19% imbalance, you should feel it. If not, don't worry, as it might be due to unprecise NCT equipment.

Only think that I would look up is the wheel alignment, as with -13m/km on front axle you will wear your tyres quicker than necessery.

Have a look at your 08 results, and the ones from this year.
Can you see the difference? Regular cars do not pass with readings of zero.
As far as i know there are two ways they can test your car - both of those are different than for regular fwd/rwd cars. Results reflect this.

TBH I don't drive too fast so no need to brake suddenly. front tyres were changed 50k ago and have plenty of thread left but rears have more so wheel alignment is definitely a issue so I will get that sorted. I travel about 30k a year

All tests have taken place at the same test centre in Cork city with 5 lanes so thats 10 cars every hour 14 hours a day 7 days a week = 980 cars a week. (980*55 EUR) Its crazy to think they could get away with uncalibrated equipment

Ok this is news to me, can anyone confirm?

What I meant was that 20% front brake imbalance would be something I would be bothered about.
But the best way to actually check if it's really that bad, would be to brake-test it. Just accelerate to about say 80km/h on flat surface, make sure there's no one behind you and apply brake firmly while holding steering wheel but allowing it to turn if it turns itself.
If car goes to the left, then it means that brake imbalance is really there.

No matter how slow you drive, it's always better to have your brakes good, as you never know when you will need to brake severely.

front tyres were changed 50k ago and have plenty of thread left but rears have more so wheel alignment is definitely a issue so I will get that sorted. I travel about 30k a year

It's actually normal that front tyres wear quicker than rear ones.

BTW - I envy you that your tyres after 50k still have plenty of thread left. I'm struggling to get 15k kms out of my front tyres.

I think OP worrying too much. .... but, have you done any work on brakes, since you got car ? if i am not mistaken, brake fluid has to be changed every 5 years.

try find service schedule, must be in handbook. there must be written, in what mileage what has to be inspected and replaced regardless off condition, but due time.

But generally ... very reliable car you've got.

First time i've seen that smoke section , what's that about

Wheres My ForkandKnife

The car is fine.I'd be happy with those results on an 06 car.Get the tracking done and the car is perfect.If you put the car into the nct tomorrow the results would be slightly different.You cannot have any car with a 100% perfect reading as there are too many variables

I'm sorry, but statements like that are among the stupidest things any motorist can say.

Stupid

I was conveying the style of my daily commute nothing more, I am perfectly aware of the reality of daily driving in Ireland and that anything could and will happen in a split second.

I like to keep the safety components of the jeep in perfect condition, hence I opened this thread. I have always maintained/replaced parts regardless of cost for unforeseen circumstances and will continue to do so
