ABSTRACT:
A brake drum measuring apparatus. There is a receiving bracket having a main portion with a longitudinal cavity and a distal, depending portion for mounting a pin to abut against the inner circumference of a brake drum. A guage member is slidably received within the longitudinal cavity of the receiving bracket, and has a main portion with a coarse measuring scale, an actuating means for operating a fine measuring scale and a distal depending portion for mounting a pin to abut against the inner circumference of a brake drum. There is a lock for fixing the position of the guage member in the longitudinal cavity of the receiving bracket. A fine measuring scale is mounted on the receiving bracket and cooperates with the actuator of the guage member as the guage member slides in the longitudinal cavity. A pointer is mounted on the receiving bracket to point to the coarse measuring scale.
