A measurement jig of friction material hardness for drum brake is provided to remove the need of manufacturing a different jig according to vehicle at the desired location through angle and length control, thereby cutting down on the hardness measurement cost. A measurement jig of friction material hardness for drum brake comprises a jig pivot formed on the same axis as a hardness meter in the longitudinal direction, angle control parts(110) connected to both sides of the jig pivot with a first adjuster and formed symmetrically about the jig pivot, connection shafts sliding-combined on one ends of the angle control parts, length control parts(160) sliding-combined on one sides of the connection shafts, and fixing units(180) which are connected to one ends of the length control parts with a fourth adjuster and rotate. |
