Need brakes to change PCD...
Hey guys. I know i have another thread about PCD and tyres but it got pretty packed up with replies so i'll start fresh.
I want to change the PCD (pitch circle diameter) of the 1972 beetle i've got... at the moment i was told it is 4x130. I want it to be 4x100 so that i
can fit some different wheels on it.
I need to know EVERYTHING that would be involved if i was to change the brake pads so that i get a different PCD. I know you can get the drums
redrilled but i'd rather upgrade the brakes while i'm at it...
Please guys any help will be appreciated!
cheers.

The simplest brake upgrade for a Beetle (assuming you already have disks on the front) is to fit a larger slave cylinder to the current rear drums.
The next step is to fit the Type 3 rear drums. The fastback and notchback have a 22.2mm slave cylnder and the Square back has a 23.? slave. In all
cases the drum surface area is much larger than the beetles.
From their you can fit a CB performance rear disk setup, or speak to seagull (?) on here, as I think he modifies ford rear disk brakes to fit to
beetles, I believe V-force http://www.beetleracing.com/catalog/ also do
the same, and so does http://www.volksconversions.com/index.htm
You can fit the late type 3 callipers to your front brakes, but this requires a bracket (again V-force or Vintage Vee dub supplies) and some
machining.
You can modify any of these setups to be 4 x 100 PCD. Check your local authorities - some Aussie engineers aren't keen on redrilled hubs and some
are ok with them.
My recommendation would be to replace / recondition the current setup so it is working as new. Then fit some good pads (I had Ferrodo pads on the
front they were great). You'll be impressed with the braking ability of a "new" standard set up, which is extremely good for a car of its age /
size.
I wouldn't recommend getting carried away unless you have massively upgraded the engine / suspension etc. I did and it has blown the small project a
little out of proportion!

Well Jeza, all i'm doing is replacing the current 1300 engine with a 1600. Its not a great increase in power but it does the job. At the moment the
current brakes are really good as they were never thrashed etc. I just want to get new PADS with a pcd of 4x100. is this possible to do without
replacing anything else. What happens to the drums that are there?
cheers

ok pads and the pcd are 2 different things.
-pads - replaceable, wear out and are puched onto the disk surface by the caliper.
-caliper- hydraulic device , fluid is pushed into form teh master cyclinder(which is puched onto by the brake pedal)
-disk- these come either as one piece to the hub or as a 2 piece unit. most oem are one piece?, they are squeezed on by pads.
-hub, this has the holes or studs, the placement of the holes or studs gives the pcd.
the drums are the same, but slave cyclinders, push shoes (not pads) onto the drum (not disk) the drum acts as the hub.
you need to change pcd, means you only need to redrill the hub/drum to take the new pcd.
if your car is still stopping fine, there is no need to put in a new set of pads unless the old ones are worn out.
I have no sympathy for my car, only the wallet that pays for it!

you also need to investigate offsets, centre bore dimensions and etc if you want to change wheels - there's more to it than just a PCD change, I'm
afraid...

ok thanks for that BiX.... too many terms for me too remember.

we can supply blank discs and we can drill them to any PCD you want.

Then what does that mean?
VWCOOL- in the last topic i created offset was explained to me quite well. I believe on the beetle i'll need an offset between 35 and 50?

in the beetle the disks and hub are a one piece unit, so therefore you can redrill the old disks or get blank new disks and drill these to whatever
PCD you like.
only a few cars had 2 piece units stock, normally high performace cars, or aftermarket performance brakes

Trevally-before you get off your arse,grab a street directory-check out where Frederick St Cavan is-then get your arse into gear and go to number 9
and talk to the Debiasi's(as already mentioned).They play with this stuff every day.When you get good information at the beginning-everything will
fall into place so easy.
