Calliper Brackets

[slimjim]

Hi Chris and LVV Team,

I am just putting together my 4B Design Approval package for my old Beetle, and as part of my modifications I would like to fit rear disc brakes.


There are a number of proprietary discs kits available from the US to convert the rear brakes of a Vdub to rear discs.


I am looking at two options, both from a manufacturer called EMPI, which is pretty well known in VW circles.

Both brake kits use exactly the same components, however there are two options for calliper brackets. -Pressed steel, and what they call Heavy Duty Cast 

I have looked though the Hobby Car Manual, LVV Standards and information sheets, but have not found a definitive answer on what option would be the better / acceptable.


Here are the links to the kits for further information

Kit with cast brackets

Kit with pressed steel brackets


Any guidance as to the way to head would be highly appreciated!


Many thanks in advance

Hi Slim

To help make a decision, we would need to know material specs for the cast brackets and dimensions for the steel brackets.

Thanks Chris,

Will contact the manufacturer in the States for further information, and come back when I receive it.

Thanks again!

Hi Chris,

After a couple weeks of trying through various channels to get an acceptable reply from EMPI, I have been put in direct contact with their manager of engineering, who is finally willing to provide some information.

He has already said in his initial email he can not supply shop drawings, as this is IP (fair enough), but willing to supply other info and specifics.

Is their any other information (other than what you have mentioned in your reply) that you would like to see from EMPI that would be beneficial towards pre-approval, and final assessment of these calliper brackets.. also forwards planning the same to their dropped spindles for the front suspension..

I would like to try hit as many birds with one stone while I have the opportunity of this guys attention, as I cant imagine there will be a whole lot of further correspondence opportunities

Many thanks again - really appreciate any guidance!

Hi Slim

As your certifier is the one who will make the final assessments of this, then I would check with them what information they would be looking for. Off the top of my head, construction method, material specifications and confirmation of suitable radii on any machined angles would be a great start.
