Abstract
To provide a friction couple having an enhanced effect and stability in a low speed range, where the friction couple has a disc brake pad having a friction material manufactured from a friction material composition having a binder, a fiber base, and a friction modifier, without containing a copper component and a ferrous metallic fiber, and a stainless steel disc rotor. The present invention uses a friction material composition containing 20-30 weight % of a titanate relative to an entire friction material composition as an inorganic friction modifier without containing an inorganic friction modifier that has a Mohs hardness of 4 or less and is cleavable. The above-explained titanate is preferably a layer crystal structure lithium potassium titanate.
