Rear disc brake upgrade
DDWR450F - July 8th, 2014 at 11:54 PM

Hi guys

Im looking to do the bolt on conversion/upgrade on my brakes to
disc brake rear end.

I was going to get the set from Steel Art but there cruising round
USA in buggies ATM& I've just ordered new wheels.

I'm looking for disc brake rear end & new rotors for front.
Stud Pattern 6 x 139.7 Landcruiser

Please let me know where I could get these from.


Cheers
DD

Google is your friend.


DDWR450F - July 9th, 2014 at 03:15 PM

Yeah thanks I've done a bit of googling but thought on here would be the place to
get some info on decent bolt on kits and the NOT so decent kits available.


Cheers
Dan

I know CBB do a bolt on kit for beetles and if I remember it was based on commodore calipers. Not sure about the 6 stud though. Easy enough to get blank rotors for a bolt on kit that can be drilled out. Also I remember chatting with someone on AVD who used to do that stud pattern. Sorry but can't remember their name ATM.
Good luck with the search.

Try talking to VWCOOL, he has a great kit. He may be able to make it suit a 6 stud disk for you.


psimitar - July 12th, 2014 at 10:36 PM

Blank rotors for the front isn't an issue as any of the Oz, UK or USA vendors should be able to help with them.

Rears ain't so easy. Only company I can think of that can make custom spilned rear hubs for different bolt patterns is these guys Airkewld rear brakes

Maybe CSP can to a special order too if you ask them.


DDWR450F - July 16th, 2014 at 09:42 AM

Thank heaps guys, yeah the 6 stud pattern isn't as easy, but Paul at Steel Art up in Brisbane
Runs these so I'll have a chat with him up at Valla.

I'll look online at Airkewld and also pm VWCOOL.

Cheers

Volksconversions on the Gold Coast had blank ones last time I was there.

Dan , I have the blank front rotors as well as the blank rear disc brake kits in stock . I don't see a problem with the stud pattern you want , ROD , 02-42729920 .


DDWR450F - July 16th, 2014 at 03:13 PM

Joel, thanks for that mate, ill give them a call to see what they have in stock.

Hmm, but how strong do you think the splines in them are? Where/who made them for him?


DDWR450F - July 16th, 2014 at 10:23 PM

Hi NG, thanks but i have a set of wheels ready to go on if i can get some brakes sorted.

psimitar, that was a concern i had when i began looking into brakes as i don't know whats good and
whats not so good…….. Ill give Rod a call tomorrow and see what he's got.


matberry - July 16th, 2014 at 10:39 PM

I've seen some rear hubs break when converted to LC 6 stud as the casting was weakened when machined for the wheel centre diameter. I know Bob Mobray of Rivmaster does it but they are high dollar racing units with alloy hubs etc and I'm unsure of road going legality.

I have a feeling the pcd gets close to the wall of the disc hat and the stud head may have clearance issues, so be sure to check.

Hopefully Rod can help


DDWR450F - July 17th, 2014 at 11:11 PM

Thanks heaps for that Matt, yeah after speaking with GT up this way the 6 stud
is a very tight squeeze!


mactaylor - July 18th, 2014 at 08:40 AM

What about using the screw in studs, no need to spot face the back and leave more meat.


matberry - July 18th, 2014 at 08:58 AM

Screw in studs are unsafe and should never be used....... My opinion again, sorry :)


Joel - July 18th, 2014 at 09:48 AM

I swear most people must fit the screw in studs with Clag school glue, they always seem to unscrew out with the nuts.

I used red loctite on mine and the loctite primer before fitting with no problems and everyone knows how often my wheels get changed.


matberry - July 18th, 2014 at 11:00 AM

It's the unknown factor Joel. The stud can get tight in the nut and come out of the drum, this can happen and if not addressed the stud can work into the nut further and have less thread into the drum, the other aspect to this is that as we know, the VW drum has more meat in the webs where the studs go. This is because the threads into the cast iron drum need to be longer for enough strength. When you restud into a 5 stud pattern you miss some webs so the threads are not strong enough any more and will fail when subjected to enough force.

You may not have had the problem, yet. One day you may be loading the suspension by avoiding a concrete truck and similtaineously hit a pot hole and have our wheel studs break due to pathetic cheap studs failing and end up under that truck......the point is, it is not sound engineering.

For me, proper studs pressed in from behind is the only option other than stock.


Governor - July 18th, 2014 at 11:04 AM

Just ordered some press in studs from Rivmaster yesterday, bit of a coincidence Matt


Joel - July 18th, 2014 at 12:31 PM

Matt, dont get me wrong, I'd always recommend press in over screw in I was more making the point most people dont fit the screw in ones properly, you often see them unscrew out with the wheel nuts.

I should have been a bit clearer, mine isnt those crappy glue in empi straight studs they are high tensile bolts screwed in from the back side of the hub so they cant undo and pull out and loctited to make doubley sure they wont move.
I'm still 4 stud, they go through the strengthening ribs.


DDWR450F - July 18th, 2014 at 08:38 PM

Very interesting guys, I don't know a lot about VW brakes, that's why I like these forums, heaps
of useful info to be taken onboard!!

Cheers
DD


matberry - July 19th, 2014 at 12:28 AM

All good Joel, just you stated using them, I wouldnt so I gave some reasons.examples why.

Governor....that's funny :)

I agree matt, but i would rather have a bit more meat left and check the studs as they are torqued up than have a disc failure at speed cause of a thinly machined press in stud on a shit casting.

I bought some rear hubs off a reputable vw mob that were about 6mm thick where the studs were to be fitted. Needless to say they are on the shelf as a reminder not to trust anyone!


vwo60 - July 19th, 2014 at 10:00 AM

Nothing wrong with screw in studs, if they have a full thread engagement, are off the same material and are fitted a as Joel suggested, therefore will have the same strength as the standard lug bolt,, I run them and never had one come out or change position, just fitted with 609 super retaining compound along with the correct primer, you would have to heat them up to get them out.


DDWR450F - July 29th, 2014 at 09:42 PM

Hi guys

Unfortunately Rod was unable to do the 6 stud rotors so I am getting Paul from Steel Art up in Brisbane
to do me up a set. He has done a fair few sets of brakes with 6 stud Cruiser pattern so I just need to
be patient as he machines them up.

And what are they costing?


DDWR450F - July 30th, 2014 at 11:03 PM

Hi psimitar

Was about 800 with 2 new front rotors, I'm not 100% sure yet! I'll be speaking with Paul at Valla and get an
exact price.
