ABSTRACT:
A brake shoe has a noise insulator sheet secured to the shoe back and engaged by the piston annular end or a caliper leg. This generates one or more high pressure areas which may cause the insulation layer to buckle and separate from the shoe. By providing slots or lances through the insulation layer immediately adjacent the high pressure areas, a discontinuity is provided which prevents such buckling and separation.
