SELECTIVELY REINFORCED Al-BASE ALLOY DISC BRAKE CALIPERS

摘要

A cast, selectively reinforced disc brake caliper has a bridge section and an outer-leg section. Each of the bridge and outer-leg sections comprises an insert having a shape similar thereto and a volume ranging from about 20 to 80 % thereof. The caliper is produced by heating the insert to a temperture of at least 50 DEG C, placing the insert into the bridge and outer-leg sections of a caliper mold, and casting an Al-base alloy into the mold so as to overcast the insert and thereby form a strong bond between the bridge and outer-leg sections thereof.
