Brake upgrade questions

[Rick_L]

The so-called "zero offset" kits use a 61-68 full size Chevy hub, with a Trans Am rear rotor, and the Chevelle caliper.

I don't know what the 64 Impala hubs do to the wheel mounting width. That would be my only concern. The calipers are fine, as long as you can find the appropriate mounting bracket. Are you lowering the car?

I don't think they do anything to it, until you add thickness of rotor. If I remember correctly people used to use them with stock drum brakes to upgrade to tapered roller bearings. The T/A rear rotor is designed to be a rear disk rotor. I have always wondered if its thick enough for front use.

[Rick_L]

If the caliper fits, it's the same thickness as the Chevelle rotor.

I guess my memory is a little foggy on these, I only had one in my time. .980 vs. 1.00

,020" doesn't mean much since there's around 1/2" of pad between the pair.

I have the full size hubs with the Trans am rear rotors and Rick is correct in that the difference is the thickness of the drum vs rotor.

Which calipers did you use? year and model?

no,I am not lowering the car!

I forgot to ask what are the hubs off of that you are using?

Your wheels appear to be 'after market' wheels... You could take one off the car, turn the wheel over, and WASH it on the back very well.. MOST wheels are identified somehow on the backside. Take a good photo and if you can't identify them, maybe one of us can help you.
I'm unaware that buying 'dropped spindles' is going to help you on the 'offset due to disk brakes'. If so, I certainly do not see the relationship there.

There are disk brake kits (without the drop) which do not offset the wheel mounting surface. This is one here which has some good characteristics, although I haven't used it personally.

Note: I would prefer to use 'factory GM' parts if possible when doing such upgrades, and there are some options for using 60's or 70's GM disk brake parts for the upgrade (although I cannot comment on any wheel offset introduced).

do you have a list of the parts and they are off of ?

I used the d52 style like the '72 monte carlo's used, my hubs were from 1965 full size impala
