'67S brakes

[tar356]

Other than the caliper and rotor, are there any other part differences between the standard and "S" set-up for 1967?

I heard long ago, that the hub might be a different dimension?

Hubs (frt) and dog bones (rear).

That's all I believe.

Yup. What Richard said.

Front Hubs; as they basically split the difference of the new 7mm spacer in the caliper 1/2. There was about 3.5 - 4mm shaved off the backside of the hub.

While the dog bones are nice to have, the same can be accomplished with a few well placed washers (never bothered Tony on the Ferrari line).

I suspect there may be other hubs?

What is a "dog bone?"

Eric, the brakes came back fabulous. I will post a separate picture thread as a thank-you.

Thanks for the replies guys...

I should be covered on the hubs.

Another question: Since the thicker hub was used from '67 on up on vented cars, I'm assuming that part #8 on the diagram is used based on the spindle, not the hub/bearing combo. Make sense?

Thanks,

Todd

p.s. Eric, still rounding up the parts to send your way!

The dog bone is a washer shaped as a dog bone or weight dumble.

If fellow S members are in search of these, I had a few exact copies made, but stainless instead of iron. They cost me roughly $5 each.

Hard to say what part #8 is without looking at the PET myself but... there's a spindle base that fits tightly in the seal. It may be that and yes, that would have no relevance to the hub/bearing combo. Those are installed and removed with heat.

It looks like that may be the base but, if we're going in order, #9 should be the base and then the seal then the inner bearing and race, then the hub, then outer bearing and race etc.

John, with fronts they moved the wider section of the vented rotor "out" so the hub was shaved a tad to do this. With the rears it moved in so... dog bones moved the caliper in 4 - 5mm(?) (Richard would know for sure) to accomodate for this. Glad the calipers arrived OK.

I'm thinking is serves two purposes:

1. To provide a surface for the seal run against.

2. A surface for the inner bearing to seat against.

I have to assume there is some sort of difference in the two strut units/spindle lengths that requires a different spacer to keep the hub assembly located in the correct plane?

I'll mock up a "vented" hub on the '67 strut and check for clearance, etc.

I'm probably splitting hairs right about now!
