12:05 Garage- ’70 Duster build

Mine ended up on the other side of the spindle:

But I am using a flatter Cobra rotor and floating calipers. Note that was a wood test piece as well, I just painted it black to get the feel of it.

I had a rough time getting the pads on the rotor correctly. My initial CAD layout had the holes in the spindle off and I got to the point where I had brackets cut and everything before I realized it. Revised my layout, had another set cut and (I think) I nailed it the second time.

In the end I am mostly pleased, but both sets of calipers I have put on the car have been spread so the outer brake pad isn't making full contact. I am planning to try a late model Challenger caliper later this year and see if I have better luck.

I would prefer fixed calipers like you are using but I don't expect to make that jump anytime soon. And the calipers you have are getting expensive, last I checked. There is a set of brackets for sale on this forum right now to use the same calipers with an MB rotor but the hub is custom and I don't know where someone would get a set. But it got me to looking for the early Viper calipers which is when I discovered they aren't something I want to buy right now.


I had thought about selling these calipers and going with the new Ford Brembo style, but those aren't cheap either, so I decided to keep these and make something work. I got lucky years ago and picked up these for $300 on ebay. I bet it would be hard to find 1 for that price now. I don't know CAD, but have plenty of friends that draw things up for me. I'll just give them a nice hand scaled ahnd drawing with all the dimensions and let them knock it out for me.
