Adhesive brake shoes are composed of friction pad, adhesive layer and metallic bed piece. Adhesive shoes have many advantages for structural usages compared with mechanical fastenings, they are used in drum brake of light-duty carextensively. But the reliability of brake relies on the adhesive strength of pads, so a rational method is necessary for estimation of adhesive strength of shoe pads. There are some standard and test codes for evaluation of adhesive strength, but theoretical analysis of strength and stress of adhesive layer hasn't found reports, only use conventional test method of adhesion or employ two or three-dimensions finite element method to analyse adhesive layer stress generated by shear or tension load in static. The adhesive strength of adhesive brake shoe is investigated both analytically and experimentally. The deformed state of adhesive layer under tensile shear loading is analysed by the finite element method on the assumption of elastic deformation. It is generalized linear relationship of stress-stress. A method of using the adhesive strength law is proposed to estimate the adhesive strength. It is shown that the proposed method is useful to predict the adhesive strength of shoe pads.
