An automatic shoe clearance adjustment device for a drum brake device which improves the ease of assembly of the bimetal member and prevents misassembly of the device. The adjuster,has a screw mechanism which automatically extends in response to the excessive opening of the brake shoes,The bimetal member,which suspends the extension of the adjuster,according to the brake temperature increase, is provided between the parts constituting the adjuster,The bimetal member,is assembled together with and affixed to a non-rotating segment constituting the adjuster

Automatic shoe clearance adjustment device for drum brakes

Matching mounting holes 25 and 85 are bored into the shoe web 22 of one brake shoe 20 and the base end 81 of the temperature sensor 80 respectively, and a clip is inserted through both holes, thereby biasing the temperature sensor in the direction towards the surface of the shoe web and into the detector hole 24, and elastically affixing the temperature sensor to the shoe web. This enables simple insertion and removal of the temperature sensor and regulates the blind movement of the temperature sensor in an automatic shoe clearance adjustment device.
