Beetle disc brake conversions
Hi all
My 58 bug is in need of some attention to its brakes and rather than rebuild the stock stuff i was thinking of an upgrade to discs all round. There
are a few kits from places in the US and one in Aus (volksconversions) like this:
http://www.jbugs.com/store/merchant.mvc?Screen=PROD&Product_Code=22-2880&Cate...
or this
http://www.airkewld.com/parts/proddetail.php?prod=2000
I haven't priced up freight and import duties yet but prices don't seem too bad for what you get.
Anyone had any experience of doing this?

call boris at Vintage Vee Dub
Their conversion will fit straight on and not widen the track, it actually narrows it by 6mm a side.
it also uses commodore pads which will be available forever
I used it on my 66 and I am extremley happy with the braking performance
Keeping it real !

Hi guys, many thanks, i love this forum such a mine of info.
Silver, did you do the rear end as well? Did you change the master cylinder from the single circuit type?
I've noticed that the US kits all seem to widen the track which i didn't want.
Cheers

I had already changed the rear end to type three drums in anticipation of Boris having these kits finished, and I run the dual master cylinder.
I am pretty fussy about most things and looked at all my options including importing a set from Germany but these happen to be the best option and
they are local ! and therefore accountable for stuff ups or available to fix problems
Go for it
Keeping it real !

all the USA kits and the Volksconversion one widen the track
Fit a new dual master cyclinder and 2 new rear flexiable hoses as well as the front disc kit from Vintage 02-9789-1777
The kits comes with rotors, calipers, bearings and hoses easy to fit takes only a few hours

I figured i'd change all the brake lines while i was at it. Mine has the small metal fluid reservoir inside the wheel well. Can i continue to use
this (or a shiny new one) with the dual circuit master cyclinder.
How about the rear discs? Worth doing? These are in most need of work, drums are pretty worn.

you should use the split compartment fluid reservoir with the dual circuit cyclinder other wise you loose the safety advantage of doing the
conversion Use the standard VW reservior then you can see the fluid level easy, chuck the shinny one away
Rear dics i suspose it if you want to go racing I have Late model Type 3 rear drums and they work great with the dics at the front

The only reason i thought about rear discs was being able to buy a kit rather than trying to scout around for secondhand stuff. I guess it is overkill
and the handbrake probably gets complicated.
If i go for late drums i assume i swap over backing plates and all internals. Does anything else need to be modified? Hang on though i want to keep 5
bolt wheels...
Thanks for info re brake reservoir. From my research it looked like it was hard to get the dual circuit type, i thought i could have a t piece in the
line from the reservoir and keep the old school one. It's a big reservoir so even if one circuit failed there would be plenty of fluid in it.
Questions questions

I have a 59 and am looking at the same things, so thanks for the info. I do have one other question that isn't here.
What is the advantage of staying with the wide 5 pattern and these custom kits, over changing stud pattern and running latter model VW disks and
callipers. Especially in light of the larger rears (and in my case and gearbox upgrade) that has the smaller stud pattern already?
Cheers...

The Vintage discs kits are available in any stud pattern
most people only want to upgard the front to discs and stay with the wide 5 rears so that why the rotors have been made this way
The better option is to upgrade the rears as well and find after market wheels that are not VW stud pattern and havethe discs are rear rortos drill
accordingally
that leaves a varity of options

Looking at the US kits, it is a lot cheaper if you change over to standard 4 stud VW. J bugs in California do a complete front and rear kit with
master cyclinder and handbrake system which comes up at just under 1000 dollars US. Ready to bolt on without mods.
You can still do it with wide 5 but it adds another 400 US or so. I was keen to keep the wide 5 as i like the old school look it gives as i was
planning on a set of wheels at a later date but maybe now i just buy a set of 4 stud wheels with the difference in price. Not sure if the jbug system
widens the track.
http://www.jbugs.com/store/merchant.mvc?Screen=CTGY&Category_Code=BrakeCompon...
Ok so it is US and not as good for having a local person to call - not to mention supporting local business - but the price is very good. Shipping is
about 100 USD plus import duty which i think will be 10% of purchase price.
Airkewld (again US) have the most awesome looking system for a little bit more money but with really slick brembo style calipers. You can also buy
drop spindles while you are at it. These widen the track though by 1inch.
I'll make a decision soon and post some pics of the changeover when it happens.

Anyone got any thoughts on reasonably priced wheels using the standard 4 bolt vw pattern that would suit the look of my early beetle. here is link to
how it looks.
http://www.twentytwentyone.net/veedub/dub.html
I'd prefer to keep the wide 5 steels but it does add to the cost.
Cheers, thoughts appreciated.

Oh well My Good advice might go unheeded
be careful of the overseas ones they will widen your wheel track ,and what pads do they use?
Do you want the discs you want ?,,,,, or the ones you want to pay for?

Hey guys, i am taking advice and i haven't decided which way to go as yet. I appreciate all comments but it would be equally foolish of me not to
explore all options.
I've priced up the local option. For the same price as a set of front discs and rebuilding my old drums I can get a complete US kit front and rear
with drop spindles and a new master cyclinder with a wide 5 bolt pattern. They use Golf pads so no problem with parts plus these are the big classic
beetle suppliers in the US which is a much bigger market than here so i doubt quality would be an issue.
The conversions are bolt on and yes they widen the track by 2.5mm per side which i think i can live with.

many engineers will NOT certify callipers that are not used on an Australian market car and some calliper brackets I've seen are a bit thin and/or
welded, which is also a no-no
Here's some "light" reading about the requirements and legalities of brake conversions that may help with your research
