<p>The brake (10) has a dust boot (26) including beads (32, 38) with annular inner and outer fixation surfaces (34, 40) received in an annular groove (36) and an external groove (42) of a brake caliper (14), respectively. The beads have respective reinforcement inserts (44, 52) that are confined in elastomer material of the boot during fabrication of the inserts by molding and are made of metallic material. The insert (44) forms a thermal screen with heat released during braking to avoid accumulation of heat inside the boot when the boot is extended in a stress position of a brake shoe (16).</p> |
