Abstract
A disc brake shoe in which a relatively thin gage, low-cost metal backing plate has bonded to one face a friction brake lining and is formed on the opposite face with a plurality of straps that are adapted to engage corresponding recesses formed in a complementary thick gage metal backing plate to interlock the respective backing plates into a unitary brake shoe assembly which can be easily disassembled to permit change-out of a worn brake shoe by simply substituting a newly lined, low cost backing plate for the existing backing plate having worn lining without the need to re-claim the backing plate for re-use.
