Looking for a source for DOT 4 O-Ring for the Cleveland brake assembly.  Most O-rings are compatable for DOT 3 brake fluids.  DOT 4 brake fluid is used in the Arcus M to accommodate higher temperatures.  DOT 4 fluid has a much higher flash point than DOT 3 fluid.  This brake fluid is not compatable with the material used in most O-Rings available.

Does anyone know of a source for the DOT 4 O-Ring used in the Arcus Main wheel brake assembly ?

Thanks again, group contributors !
