Application No. 08/411,202
Claim 5
We sustain the rejection of claim 5 under 35 U.S.C. §
103.
Independent claim 5 reads as follows:
A disc brake assembly having a pair of brake shoes
to be pressed into contact with a disc rotor secured for
rotation with a road wheel of an automotive vehicle,
wherein each of said brake shoes has a friction pad
member having an upper portion opposite a lower portion,
the upper portion having an upper width less than a lower
width of the lower portion, and the upper width in total
is less than about 1/12 of a circumferential length of
said disc rotor at a position where said disc rotor is
brought into frictional engagement with the upper
portion of said friction pad member.
Hummel's invention relates generally to brake systems of
the type used in domestic road vehicles, and particularly
concerns an improved brake friction pad assembly having an
elastomeric noise-damping material incorporated into the
assembly only after complete material thermal curing. As
shown in Figures 1 and 2, the disc brake friction pad assembly
10 comprises a molded friction pad element 12, a thermally
cured elastomeric adhesive film 14 adhered to the mating
surface of element 12, a metal backing plate element 16 for
