HR600 TRANSAXLE - BRAKE DISC WEAR CLEARANCE CHECK
The purpose of this check is to determine the "worn" thickness of the inner
(friction) brake discs. The remaining thickness of the inner plates is readily
determined by measuring the space (clearance) between two steel outer
discs. The minimum allowab'e "worn" thickness of the inner friction discs
is [2,6 mm] 0.104 inch. Measurable wear of the steel outer discs is normally
not expected. The brakes must be fully applied during this check to make
sure that all of the operating running clearance is removed.
