A brake stroke indicator, comprising a L shaped indicator member disposed on the push rod clevis pin, and a concealing means. The indicator member comprises a first section with holes to connect with the push rod clevis pin and slack adjuster, and a second section of highly reflective color surface angularly disposed to the first section. The indicator member moves with the clevis pin, and oscillates as the push rod is reciprocating. The indicator member hides behind the concealing member while the push rod reciprocates within safe limits. The second section of indicator show up out of the concealing means when the push rod goes beyond its safe operational limits.
