Request for information - technical drawings of parts

[Chris Percival]

I need technical drawings of 1303 beetle drum hubs and Porsche caliper mounting positions. This is so I can easily create a plate to hold my caliper onto my beetle drum brake hub. Anyone got any or know where I might find them?

Try this link http://www.ricola.co.uk .I'll put a drawing of the bracket you need for the 944 NA caliper shortly..

The top holes are m12x1.5 the lower ones are 10.2.Thicness of the plate is 10.5 ,But check how much your spindles have been machined .I used disc stubs and had to machine the the spindle down to leave 10mm .This got the caliper in the same position as the 944.
I have just done this (torsion bar type)and still have the 944 spindle to check if you need to.

I am aware of Rich's site, but he used radial mount calipers with a disk brake spindles. I am using non radial mount caliper with drum brake spindles.

Ideally i could get a drawing with dimensions of the holes in the spindle and how far the caliper mounting holes are from the center and their angle apart.

Then I could just give a technical drawing to someone to cut the brackets.

I will probobly make a template using some old brake backing plates and a little trial and error.

What caliper are you using.The section i looked at in the speedster bit used drum spindles and a 83-85.5 caliper.
