Brake caliper carrier material- Help

[ml32]

Hi to all the experts here....

I'm planning to have some brake caliper carriers made up for my Audi RS6 V10 and wanted to seek advice as to what is the best strongest/toughest material to use.

The brake kit in question is the OEM Ceramic brakes but I have sourced a pair of Audi Q7's calipers. The Q7 calipers are identical to that of the RS6 with only the carriers being different.

The original carriers are made from cast Iron.

I have done a bit of research and found the below materials are suitable for carriers fabrication but just not sure which is best.

6061 heat treated
316SS
7075-T6
CNC machined from solid billet 1018 steel, yellow zinc plated.
7071 Aluminum/Powdered Coated.

Thanks in advance and any help on this much appreciated.

Personally, Steel is the only material I would use out of those. Any other material would introduce a not insignificant amount of risk of galvanic corrosion and differing co.eff of thermal expansion effecting the mechanical fixing.

Have a word with BG Developments. It won´t cost an arm and a leg and it´s top notch work.

Depends entirely on the space available and the design. You could make toffee work if you used enough of it.

I made some parkin once that was stronger than titanium.

Here´s the calliper mounts BGD made for me. they´re alloy, and they´re beautiful

Here´s the finished setup with AP Radi-Cal F3 callipers and discs.


They´re working on my rear disc set up now, using the inside of the disc bell as a drum parking brake, using brake shoes from a scooter

I forgot to mention the calliper mounts are ENP to ward off corrosion. But not in that picture, they where done after the picture was taken.

And 'ENP' is?

(Not any of these: http://acronyms.thefreedictionary.com/ENP)


How is it better than Anodise?

Electroless nickel plating.

Ah, I was going to suggest Electro Nickel plating, but thought, nah, over aluminium? Sounds interesting, I'll Google......
