Abstract
[Object] To provide the underlayer composition for the disc brake pad, which may be applicable to the manufacturing process of softening the rubber by heating even if the uncrosslinked fluororubber in the underlayer composition and the disc brake pad with an excellent brake noise suppression effect. [Means to Resolve] To use the underlayer composition containing 5-15 weight % of the uncrosslinked fluororubber relative to the entire amount of the underlayer composition, 4-8 weight % of the phenol-based resin as the binder relative to the entire amount of the underlayer composition, and 0.3-2 weight % of the hexamethylenetetramine as the curing agent for the phenol-based resin relative to the entire amount of the underlayer composition.
