Flipping useless ADR!!!!!

psimitar · 2011-11-10T19:45:54+00:00

So I wonder if anyone can help answer this one for me whilst I await QLD transport to get back to me. I was wanting to fabricate a vented brake disc conversion for my 1959 Beetle with 205PCD original steels. Now even tho Volks Conversion and CSP with TUV approval, better than the ADR too, sell similar kits that require a mounting plate to bolt to the discs hub and then the 205 wheel bolts to the mounting plate yet my engineer says this may not be legal unless ADR has made a specific allowance for this? Does anyone know if it's legal or not? It's not a wheel spacer or adapter to change from one PCD to another so technically it should be allowed. Strength would be better than the original drum so can't see why the dumb ADR wouldn't allow it. Cheers

My calipers mount with 12mm bolts standard, i cannot work out how they allow adaptors to mount porsche calipers using the two 10mm bolts that attach the standard caiper to the ball joint spindle, you are generating far more load with the bigger calipers, he is a automotive engineer and accepts the responsibility for the mods anyway, he has demand a very high standard fort all the mods that i have carried out with him.

I can see the reasoning behind it and agree so long as the spindle material for the bolts can handle being tapped out but what I find amusing is the NCP say the spindles can't be modified. Been a while since I read it but just amusing if I remember it correctly and the engineer can override that which is written.

Like I said tho I'd love to see a build thread as I will for mine once got the go ahead on the design 😉

Be aware that the engineers primarily design of bolt fastened components is to induce friction between the two contacting surfaces (eg: caliper and stub axle or adapter etc), thus have the friction to take up the load as opposed to relying on the bolts to take the shear strain of the load across the bolts cross-section. If 10mm bolts can hold enough axial tension to induce friction between the two contacting surfaces then your set. The automotive engineer should have taken all this into account.

Quite so Chris. Not much surface area on those caliper spindles. Personally I'd use drum spindles for better location and the bracket kicks forward just like the caliper one would so better in my opinion 😉

I read it on samba, so it must be correct.

Sometimes Volkswagen dealers sell spare parts. Amazing isn't it!😂

I must say it impresses me how many people on here are prepared to put in the effort to abide by ADRs.

I won't mention names but members on other forums I'm on would be perfectly satisfied holding calipers on with a couple of old coach bolts, some fencing wire and a bit of silastic to stop the rattles.

Sounds about right mate. Gotta love all those illegal vehicles out there that fortunately you can rely on the CTP in rego to pay for your rehabilitation as even if they have insurance it's invalid due to a non-comforming modification. Those people should be shot 🙂

I do like Clarkson. Least he says what a lot of people are thinking.

Oh and Richard Larson couldn't even be bothered to answer my emails. I don't have the time during the day to fone and in this day and age I feel unimpressed if someone can't respond to there emails no matter how busy they are.

Anyway, lets hope my original engineer can help when I return in March.
