Hello, Albert.
>From the pics, it looks like the caliper bracket replaces the bearing
retainer and must therefore carry the hub oil seal - clever! I'd be inclined
to suggest that making such brackets from scratch would be a costly and
frustrating business. I expect it could be done but are these brackets, or
indeed the entire conversion available to buy? I think this may be so; who'd
make up patterns for one-off castings?
I reckon that making up the hub rings from steel stock, then having the
bracket sections MIG or TIG welded in place, plus the refacing necessary to
take out welding distortion would be an expensive business. Plus, in steel,
the whole assembly would probably be considerably heavier than a pair of
drums, not only increasing the unsprung weight but, arguably, upsetting the
car's polar moment of inertia. Whethet this would be significant would
involve knowing how much extra weight is involved.
Given the costs of machining and fabrication, I'd check this out - you may
well find it cheaper in the long run.
Please let me know what you find out.
Cheers,
Dave.
