IVA fail :-(
Just got back from chadderton IVA test on my J15 and failed. But as far as fail lists go, I reckon this is a pretty good one!
Only one item!! Handbrake efficiency was 11% when the minimum requirement is 18%.
I don't know how hard he pulled the handbrake lever cos the sent me to the "coffee" room for that bit of the test. No idea why.
So I've driven all the way back pulling the handbrake on and off for nearly 20 miles to try and get the pads to bed in.
I'll have a look at the lever to see if I can improve the pivot point and whip the cables off and give em a good greasing etc.
All in all - a very happy boy!!

Hell! He was a bit hard! He could have let you drive around the centre with the hand brake on, couldn't he?

Yes that was well mean, could have at least given you the chance to improve it.

Can you drive the car without an IVA?

Sure can. You can drive to and from pre-booked IVA appointments and to and from garages etc. to pre-booked appointments for work to be done to fix the
specific fail items. It says it at the bottom of the IVA appointment letter.

That's a very picky fail indeed, but easily sorted for a quick retest. You must be very pleased overall 
Smashing looking car too BTW!

11% handbrake efficiency is pretty poor what rear callipers are you using ?

I'd be more concerned why he 'sent you away' for that part of the test??
Sounds a little iffy to me  Maybe he just wanted to find something to fail on?
Or maybe I'm just jaundiced? 
It looks like the Midget is winning at the moment......

Oh dear...what a shame...and just one point.....
Are you using the sierra Calipers of the VW ones?....I'm just in the process of getting my VW ones in on my J15 build.

When I took my car to Derby years ago a Westfield was being tested in the next slot and his handbrake was inefficient. It was a brand new disc set up
and the tester was practically stood up in the car trying to pull it on with both hands. He sent the bloke off to drive round the centre with the
brake on for 5 minutes while he had a coffee and it just made it through when it was tested again. I don't think it's part of their brief
to find finicky fails.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Well done
Nearly there, just as the weather improves as well, looking forward to my test even if i fail as the drive is 95 miles one way over the Lincolnshire
wolds !

I also got sent for a coffee when they did the brake / speedo / noise / self centering testing. Two testers did it all, with one driving and one on
equipment. This was at chadderton. I found the tester (dave?) to be fantasticly helpful. Allowed me to fix a few issues on the day.

Another J15 virtually on the road, well done. Have you got the cable attached to the front or rear position on the handbrake lever? If on the rear,
try it on the front. I had Sierra calipers and M1144 pads but I had done a shake-down track day before IVA and passed no problem.

Hi Guys,
thanks for all the positive comments.
I am really dead chuffed to only have this one, and I think I've worked it out. I am running the standard Sierra callipers with ordinary road
pads.
deecee09 - are your pads slightly offset ie, is it obvious they are going to lip the disc in the fullness of time. mine do by about 5-6mm, with the
corresponding few mm of pad hanging in fresh air near the hub. JP says this is normal!!
I repositioned the handbrake lever to do away with the pulley so in theory, it should be more efficient.
As pointed out, the discs and pads are brand new and most definitely not bedded in yet, or rather they weren't at the time.
To be fair the tester, Gary Wild, he did say that the drivers side was a lot worse than the passenger side, so that was my first port of call.
Up on the axle stands, handbrake on, I could only just move the passenger side wheel a tiny bit by hand. The drivers side was relatively easy!!
Adjustment way off between the two wheels. Easy to spot after the fact!!
Took all the offending covers off. Plenty of lithium grease on every moving part, WD40 down both ends of the handbrake cable dozens of times, more
grease over the cable entry and exit points. Work in with handbrake lever until arm goes numb!!
Whip the callipers off and regrease and realign the sliding calliper "pins". Find a knackered rubber seal on a re-conditioned calliper.
Again, easy to notice after the fact. Replace when spares turn up.
In the meantime, reassemble the whole lot and apply the handbrake.
Can't move either wheel with my hands at all. As it happens, the only way to rotate either wheel now is using one of the wheel nuts with a three
foot breaker bar, and even then its not easy.
That should be that! Roll on Monday - then prepare to do battle with the DVLA!!

Took mine to the local garage to do a MoT type testing prior to the IVA. Guess what, the hand brake efficiency was the same as yours. Learned advice
from John the tester, who I have known for several years, was to drive to the iva stabbing the brakes every time I got over 30Mph and take the long
way to the IVA station.
P.S. My rears are Passat/RD OEM's

Bizarrely and somewhat suspiciously, it passed MOT 4 weeks ago!?!? I know the guy who did the test, but I most certainly didn't want or ask for
any favours.
If this had shown up then (did they check it??) I would have a VOSA certificate by now.

Paul I have some pics but am having trouble uploading them. If you send me a U2U with your email I'll send them. I had to modify the
uprights, calipers, caliper bracket and outer pad to get them to fit properly. Pity JP could not have designed his fabricated calipers to suit
without mods.

PS I suspect standard pads are fairly hard so will need more bedding in?

The brake test at IVA is not the same as that done for an MOT. It's more complicated and as a result I think the testers might want you out of
the way so as not to get distracted.
Also, the efficiency is worked out based on weight. MOT uses a fixed weight for the specific vehicle. IVA uses actual weight from their scales, plus a
fixed amount added for passengers/luggage. Without knowing that the MOT result wouldn't be comparable with IVA.
