Date Nov. 24, 1994A brake shoe, in which a friction lining is secured to a platform of a shoe body solely by a thermosetting adhesive resin cured at elevated temperature, has a friction material including fibrous reinforcement materials and an uncured thermosetting binder, roll formed to define a green lining element which is sandwiched with the adhesive between the platform and a bearing surface that applies small constraining pressure by way of the major faces but not minor faces. The resins of the adhesive and lining element are cured together in situ on, and into intimate conformity with, the platform. The constraining pressure is preferably long enough to overcome any tendency for the curing friction material to expand in thickness or fall in density due to evolution of gases therein, by easy escape of gases from the unconstrained minor faces permitting the small constraining pressure on the major surfaces. To effect an increase in density of the lining by way of a decrease in thickness with only small changes of the minor faces.
