Hello everyone...

recently bought a Rod Millen built 1990 miata.

I'm trying to get the thing road worth, but am having issues with the front brakes...

The rotor on one side is warped and the pads on that side are falling apart...I havent looked at the other side yet..

My main issue is that these seem to be completely custom... The caliper mount is welded to the wheel hub and the rotors are a two piece design.

Anyone know what size rotor this is? or where I can get replacements?

I can take pictures if needed.

 

Take lots of pictures of the whole car. I want to see some of this automotive piece of history.

I still have the Road and Track magazine when Rod Millen debuted their first turbo car.

 

I've got a Rod Millen front lip on my car but it has stock brakes so I'm not much help.

 

Can't you tell what size a rotor is with a ruler?

 

Yeah I would look at the brake hubs and see if they have a manufacturer listed on them, then I would measure the outer diameter of the rotor disk and the bolt diameter of the disk and number of bolts and cross reference that with all the companies that make 2 piece rotor parts like wilwood. You should be able to figure out the pads you need based on the model of the calipers, there's got to be some sort of identifying markings on them.
