I searched ebay and the WWW, looks like no one sells this (overseas) anymore. Nothing on Ebay. I'm changing over to discs again and need it for the caliper brackets. Someone here willing and able to get it localy and ship to Germany? In Germany you either get 6 or 8mm. 6 is a bit too thin, and 8 too thick.

Why do you want to use 7075? It is very strong but prone to corrosion and can't be welded. How big a piece do you need? IMHO 2024 is almost as strong and not as prone to corrosion.

It will be painted and it is the strongest (regular) aluminium. No need for welding, I would never use welded aluminum as an caliper bracket anyway.

I have a sheet of 5052 but might be able to get you 7075 if I know how much you need.

Sid, would McMaster Carr ship to Germany? They sell it and you can get what you want directly from them.

....from their website;

(The guys with the "inexpensive" tools [forgot their name] will not ship to Canada.)

Why not mill down a 8mm piece to 6,5 - 7mm?

My reason that I piece together a disc brake kit is to safe money. I could buy one from Wilwood with brackets that i could convert to FL spindles for 800-900+ +shipping, tax, duty.
I don't have a the facilities to mill down anything. I would have to let it done in a shop for $100 000/h or someting like that. I could as well buy that aluminum sheet on ebay right now for $320 + shipping.

My '57 Chrysler has Wilwood brakes retrofitted onto its spindles.
I once start writing down all the partnumbers to copy the setup to another car, but costs added up quickly and decided I was better off fabbing my own.

I have a pic of the setup somewhere I could post if you want.


How big of a slab of aluminium will you be buying if you have to pay $320 for it?
For how many cars can you create adapters?

It is 12"x24" piece. I converted to Wilwood brakes almost 20 years ago. 4 piston calipers with vented rotors. My Fury works so well and troublefree that I'm making my other Golden Commando a technical clone of it (not just the brakes). I posted the Wilwood part#s here some time ago.
Also the conversion is so easy and straightforward, with OE spindles and hubs, it is hard to beat. You may can cobble together a kit with other parts, for a few dollars less, but when it comes to bracking, I make no shortcuts. Wilwoods are hard to beat. They are very light, that makes a noticeable improvement in handling, performance and comfort.

Don't know if these dimensions will do you any good.

My '57 has a similar Wilwood system I think;




I agree the braking is just about perfect and especially braking hard from high speed, you can really feel the brake-system clamp down on the rotors and bring everything to a halt.

But then again, the converted discbrakes on my '62 NY wagon using '73 C-body rotors and single piston calipers will just about put you through the windshield as well for about the costs of 1 Wilwood caliper.

Thanks John, but that is 6mm, I can get that in Germany. Don't want to go under 1/4" which seems already very thin for a caliper bracket. I know that it works, otherwise I would go bigger, but can't go over 8mm (see picture).

I understand; I tend to over-build things in favor of strength, if I was fabricating a 1/4" caliper bracket I would use steel.

Yes, I just always try to keep unsprung weight as low as possible and the 1/4" bracket came from Wilwood. Keep in mind, the brackets are only sheer-stressed, that makes the thickness not as important (provided there is no disc sideplay).
