Vented disc brake rotors

vwo60 - November 24th, 2012 at 07:25 PM

My vented disc brake rotors arrived this week from the UK, they will fit ball joint and link pin spindles, 20MM thick, also have bought some calipers to suit, they also bolt straight up, just have to get them engineered

Hi

Nice, are they off another model car? Some engineers get a bit scared by non OEM stuff.

Steve

vwo60 - November 24th, 2012 at 09:01 PM

NO, they are a direct replacement and are TUV aproved

mactaylor - November 25th, 2012 at 04:55 AM

where are they from?

vwo60 - November 25th, 2012 at 06:16 AM

Get they from the UK, very common in europe, i always wondered why no one used them in Australia.

Hi

CSP have them.

TUV approval is well respected, I hope the bureaucrats understand what a TUV approval means.

Plenty of CSP brakes on the road in Australia, lets hope they are approved, also the wilwood calipers and disc's that i see fitted to the Red9 suspension on kombi's by a sponsor of this site, I am told They are approved.

What calipers are you using with them?

Hi

A long time ago I asked an engineer about the feasibility of using a Willlwood calliper as a hand brake only calliper. He would only pass OEM callipers.

Some one is approving the wilwood calipers on the kombi's that i have seen, dasdubber might like to comment, i have some porsche calipers and some mazda calipers, both four spots, i already have fabricted a set before and even machined the aluminium hub and made the 12MM thick bracket to afix the caliper, all aproved and engineered, i had to give him a CAD drawing of my proposed caliper bracket and aluminium hub, passed first time, I have spoken to the engineer and he see no problems with the hubs.

thats exactly what I thought, I recommended them to who owns my BerT3 drop spindles as a kit already exists that bolt on using these disks.

Let me know if they are approved.

hulbyw - November 26th, 2012 at 08:20 PM

As I understand it in Vic, TUV approved parts don't pose any problems to get passed by the engineers. So vw060, are you going to tell us which company you imported them from?

Take of the vat, freight was cheap at about 50 pounds using UPS.

Burrelli - November 26th, 2012 at 10:33 PM

I have had a bit to do with a CSP kit on a Type3 with the discs like that.They ad 6mm a side to the track and you can not fit the backing plate. Also the caliper does seem to flex a fair bit more than a standard caliper with out the spacer for the wider disc.

Other than that they seem good. They are not TUV approved for a type3 only a type1.

vlad01 - November 27th, 2012 at 08:12 AM

ah caliper flex, love that stuff :spin:

vwo60 - November 27th, 2012 at 11:22 AM

On my car the rotor does not increase the track at all as it is a direct replacement for the standard rotor extept for the rotor thickness which is towards the inside of the car, just have to readjust the position of the caliper with a spacer, trial fit carried out and all is well

vlad01 - November 27th, 2012 at 02:18 PM

sounds good.

I got ISP billet hubs waiting at the post office, trying a similar thing with having the face machined down 3.5-4mm to reduce the track increase from using disks and eliminate the need for spacers washers on the caliper as Glenn provided.

they are 18mm think so even down to 14mm think its is still ridiculously think, heat treated 4130 btw. not sure about engineering cert on that, i'll work it out.

vwo60 - November 27th, 2012 at 04:06 PM

I made the front and rear brakes on my early beetle, machined the hubs out out of 6000 aluminium in T6 form,
twenty MM vented rotors andon the front have mazda four spot calipers, all engineered and approved. No increase in track over the beetle rotors when fitted to the link pin spindles.

Hi

Slightly off topic but i saw a post on shoptalk forums relating to VW factory 4 spot brakes on Swedish Type 3s http://vwtype3.org/scrapbook/4pot/

You learn someting everyday about VWs.

Steve

vwo60 - November 27th, 2012 at 05:59 PM

That is very interesting how the calipers are two two pot calipers with it's own brake circut for each one, i wonder are they steel or aluminium, learn something every day, thanks Steve.

Do you have any idea if using these with a permenantly attached plate for wide 5's would be passed by an engineer?

Can't see the problem myself if engineered correctly put what would I know

vwo60 - November 28th, 2012 at 06:56 PM

You would have to ask a engineer, there is a lot of different opinions about adaptors and calipers like the wilwood, it is obvious by the fitment of the wilwood calipers to certain vehicles on the road that there has been some loose interpretation of the rules, i have been told by the guy i use they are not a propritory caliper, also they do not have dust seals on some of there models

I agree, when I approached him about guidance for fitting a WRX motor into a Beetle he said I had to be joking and hung up

It amazes me how little these engineers seem to know about aftermarket brands. Wilwood and Bear brakes are huge in the USA and better made than most OEM cast sliding calipers.
Taorx, Brembo, AP Racing, etc etc are all miles better than OEM. Heck Brembo are OEM on certain BMW and most Porsche vehicles.
Seems as tho most don't wish to properly earn their $120 an hour if something is a little different from making a boiler :lol:

If the part you want yo use has not been through the ADR process it is safer to take the "I do not want to know about it" route, if the engineer approves it he is lible for any issues that arise out of his approval, if there is a fatality he would be in deep dodo, so i suppose the safest thing to do from there perspective is not to allow the use of the part or disign, saying that i was still able to disign my own hubs and machine them myself for my early beetle and get them approved, just took a while.

Ah yes, that lovely ideal that has come from the USA. Sue for everything. Liability insurance is getting ridiculous these days.
I mean, I get that they don't want stuff like that on them and would prefer something that has been pre-approved by a government department as it takes the blame from them, which is what it's all about these day 'the blame game'. But at the same time for the money you are paying them they should have sufficient training and knowledge to be able to ascertain if a design or product is safe and strong.
Especially when you think of the fact that even a well made caliper like Wilwood would pass it's in house inspection but because a seal had a slight imperfection in it then it fails after only a few thousand K then it is no one's fault as you can't test for every eventually and shit happens.
This is the real world and the craziness needs to be reigned in
