Does anyone know of a catalog, chart, or listings of dimensions for replacement disc brake rotors? Rather than go the route of rotor hats and rotors, would like to find some cast rotors close to the dimensions I need, and then make caliper adapters to fit. Would be looking for rotor OD, rotor thickness, and offset or a relative dimension from the hub mounting face. Thanks in advance.
Not a good way to do it. Get the rotors and calipers first then build the adapter plate. Even if you have the measurements listed above, many times the hub is going to sit in a different place due to the requirement for a spacer. Said spacer, sometimes thin, sometimes thick and sometimes not at all. Keep in mind that many hot rod disc brake setups that use factory parts are combinations from different years as well as different makes. Granted, it looks like you might save some time building it now and then installing the parts. Most times you'll find more time is wasted doing it over than simply being patient and waiting for parts you can build to.
Uh, I think you are missing the point, You still need the dimensions of the hat and bolt pattern at least to get the rotor to fit your hub. I could not find any listings, I even talked to the guys at the Brake Parts warehouse in McHenry Ill ( I am a contractor that does calibrations for them), they are the single largest distributor and warehouse in the country, they had no listings by size, only application. I ended up taking my cleaned up hub to a local NAPA sotre on a tuesday morning with a couple cups of coffee and a dozen doughnuts, counter guy set me up with a razor knife to open the boxes, and a rol of tape to close them back up, spent about 20.00 and an hour, another good thing about this method, I now have rotors that are common and stocked by NAPA. With my luck, the perfect rotor dimension wise would fit a car that was made for 1 year, and was not sold in the US. FWIW Ford Explorer rotors fit perfectly on my 53 Plymouth Hubs, and 1987 Bronco Rotors fit my 50 Chrysler (8Cyl=5 on 5 1/2" pattern) Hubs
www.brakewarehouse.com It takes some work but they were the only one that had the info when I was looking...
napaonline.com has rotor diameter, thickness, and total width in their descriptions, but it has to be looked up by make and model. It would be nice if we could get a database started, so murfman, if you have some dimensions from your NAPA trip, it would be nice if you would post. Piper106
If your going a hub/rotor ***embly I would pay attention to bearing id/od and distance from bearing to bearing, otherwise go with bolt patterns first and go from there. I was halfway thru a brake setup for my 55 than Scarebird came out with a kit. I ditched mine and got his. Saved me alot of time. His whole approach is to make a brake kit with parts you can get at any good parts store. What are you trying to put brakes on?
Here is one I found. Wish it went further with time. http://www.uglytruckling.com/Technical%20Topics/Rotor%20Spec%20Sheets.html
