ABSTRACT:
A disc brake boot seal 10 (and method for assembling a disc brake system) that is molded in its extended condition and that when moved into its collapsed condition will remain in its collapsed condition. The boot seal comprises a molded elastomeric sleeve 12 having a plurality of different wall portions 20-34 certain ones of which interact to releasably hold the sleeve in its collapsed condition so that it does not self-extend. The expense and high mold breakage resulting from the prior art system of molding a seal in its collapsed, convoluted condition are eliminated by this invention.
