Bell mounting face definition
Bell mounting face means the surface of a brake disc that goes in contact with wheel hub. The mounting surface is calculated between the disc inner diameter T(i) and a diameter T(o) defined as the max diameter of area subjected to flatness restrictions as indicated on disc drawing (see figure 1). In case indications on the drawing are missing, T(o) is defined as follows: T(o) = T(k) + B + 10mm " E/ECE/324/Rev.1/Add.89/Rev.3/Amend.8 E/ECE/TRANS/505/Rev.1/Add.89/Rev.3/Amend.8
