PURPOSE: A method for judging the replacement time of a friction member is provided to prevent braking performance from being degraded and damage to a drum by informing a driver of excessive abrasion of a pad and a lining corresponding to the friction member. CONSTITUTION: A method for judging the replacement time of a friction member comprises following steps. An actuator is operated(S600). Whether the actuator arrives to goal active operating or not is decided(S700). Information is collected after completing a process measuring current increasing or the change of stroke(S800). Abrasion limit value is determined(S900). A driver is informed of the replacement time of the friction member(S1000). |
