Document Type and Number:
Japanese Patent JP6764216
Kind Code:
B2
Abstract:
[Object] To provide a friction material, which is manufactured by forming a non-asbestos-organic (NAO) friction material composition, used for a disc brake assembled in such as a passenger car, which does not degrade the inhibitory effect of rusting and prevents seizure due to corrosion even if the automotive while the parking brake in operation is left under a high humidity state for a long period of time. [Means to Resolve] A friction material, which is manufactured by forming the NAO friction material composition including a binder, a fiber base material, a friction modifier, a lubricant, a pH adjuster, and a filler, where the friction material composition contains 2 - 6 weight % of alkali metal salt and/or alkaline earth metal salt as the pH adjuster relative to the total amount of the friction material composition, 1 - 7 weight % of fibrillated organic fiber as the fiber base material relative to the total amount of the friction material composition, and 0 - 0.5 weight % of water-repelling component relative to the total amount of the friction material composition.
