A brake compensator for use in a servicer that supplies sheet material at a predetermined tension to a tire building drum. Such servicer has a plurality of supply rolls journaled on bearings wherein the bearings have support frames that are fixed to the frames. Collars on shafts that have brake material thereon rest on the support frames and have cooperative surfaces that provide a tensioning to the fabric that is proportional to the quantity of material on the supply roll of the shaft.
