Identify rear brakes?

[Hebster52]

I have no idea if these are split or maybe even Barndoor rear brakes?
How can I tell what they are?

Looks like Zwitter and early Oval (1953) rear brakes.

At first glance they look like Jan 52 to Dec 53 Beetle brakes, since there are only two brake shoe return springs.

Is the star wheel leaf spring attached with 2 small screws, or crimped on? Crimping started end of Oct 53.

What is the bore of the 4-bolt wheel cylinder? Rear cylinder bore increased to 17.5 mm, from 15.9 mm, in Oct 52.

Ok. Thanks. It is crimped on. Not measured the cylinders. The brake shoes are 30mm so seem to be 52-53 ish then?

Well, based on the backing plate design, it has to be Oct '53 to Dec '53. Yes, 30mm wide shoes. If original, the wheel cylinder should be 17.5 mm; there might be a number on the cylinder casting.

Jan 52 Beetle brakes had three brake shoe return springs.

From October 52 (Zwitter) two brake shoe return springs.

Well, my copy of "Progressive Refinements" says otherwise. It says that on 26 Jan 1952, beginning with Type 1 chassis # 1-0318328, the former two springs (at the adjuster block side of the backing plate) were replaced by a single spring, and thus at the same time the angle brackets for the former springs were eliminated.

Strange but probably the data from the "Progressive Refinements" are more accurate.
So the version with the 2 brake shoe return springs has entered from chassis number 1-0318328 (26 Jan 1952).

hello all the photo shop pics are gone, can someone show what the front and rear brake shoes look like for may 52 using only two springs, also are the screw adjusters straight front and back or on a angle.

thanks 52 hebster, mine are as your photo, two spring setup, can you confirm that the screw adjusters are slotted front and back.
