ABSTRACT:
To control initial shudder in a wet paper friction plate, the frictional sliding surface of a wet paper friction member is preconditioned by frictional sliding contact with a mating plate until its bearing length ratio tp at a cutting depth of 10 μm is in the range from 70 to 85%. The preconditioning is optionally preceded by grinding, preferably before the wet paper friction member is attached to a base plate.
