Master Cylinder
So apart from price, does anyone know what the difference is between a Beetle single circuit master cylinder, and a type 3? Problem i'm having is i'm pretty sure my 66 has had a beetle brake conversion as it has 4 stud wheel pattern and discs on the front.

Re: Master Cylinder
The pushrod on a T3 is longer than the beetle one so you need a matching T3 cylinder so the story goes, in practise it may be worth trying the beetle version. I was able to find a nos T3 one cheaply in the end which is working fine
Physically I think the 2 units are very similar

Type 1 Bolts in from inside the car, Whereas Type 3 is mounted from outside
You'd need to check the Master cylinder bore and be aware that front drums requires a different M/cyl to Front Discs

Re: Master Cylinder
As I've got front discs and a 4 stud bolt pattern in thinking it may be beetle anyway, useful info about where it mounts from, I'll check that out.

Re: Master Cylinder
European Type 3's were Disc brake and 4 stud in 66 anyway, so I don't think its converted.
66/67 master cylinders are the same bore and stroke as Drum, but have a valve incorperated into the body that leaves slight pressure in the system - to prevent the pads working back. In practice it doesn't really happen, but just so you're aware.
The Beetle cylinder is the same bore, but because the Type 3 cylinder is longer non of the internals fit - I know...
You can get a Twin circuit Type 3 cylinder off the shelf. They'll be a little modification to the solid pipe lengths, but its a worthwile modification.
