ABSTRACT:
Disc brake for heavy-duty application in which peripheral portion of disc has cooling passages to conduct cooling liquid therethrough to remove heat generated by braking. Rotary seal cooperating with disc conducts cool liquid to and if desired can return warmed liquid from the cooling passages. Cooling passages are generally zig-zag shaped and disposed adjacent and extend between braking faces of disc. Passages include plurality of radially and tangentially disposed passages connected by adjacent inner and outer ends. Tangentially disposed passage portions are shorter than radially disposed passage portions. Radially disposed portions are separated by partitions having generally parallel side walls so as to eliminate relatively thick portions of material to reduce formation of hot spots on braking faces.
