  A friction member which is suitable for use as a friction facing member in a transmission is provided. The friction member includes a uniform density heat resistant paper, a first layer of thermoset polymeric binder coated over and at least partially impregnated into one major surface of the paper, granular carbon friction particles uniformly distributed over and partially imbedded in the exposed surface of the first layer and a second layer of thermoset binder over the first layer and partially imbedded granular friction particles which coats without obscuring the granular friction particles. The friction member is made by applying a coating of liquid thermosettable binder filled with carbon particles to one major surface of the paper, supporting the coated paper and a movable carrier, applying a uniform layer of carbon friction particles over the binder layer, at least partially curing the binder layer, applying a second coating of thermosettable binder material over the carbon particles and curing the coatings until the binder material is thermoset.
