Abstract:
1. A brake pad ( 10 ) for a motor vehicle disk brake received in a hydraulic braking caliper ( 12 ) and operable to be applied by said caliper ( 12 ) against a rotating brake disk, the brake pad ( 10 ) comprising at least one plate-shaped support ( 20 ) of which an active face ( 22 ) carries a lining ( 24 ) made of a friction material and to be applied against the disk, and of which an opposed application face ( 26 ) is directly engaged by at least one end bearing face ( 18 ) of the caliper ( 12 ), characterized in that the application face ( 26 ) of the pad comprises at least one reservoir ( 28 ) of grease ( 32 ), of which at least one destructible wall ( 30 ) is to be directed toward the bearing face ( 18 ) of the associated brake caliper ( 12 ), is to be mounted with a clearance (J) with respect to said bearing face ( 18 ) of the caliper ( 12 ) during the operation of mounting the pad ( 10 ) in the caliper ( 12 ), and is then to be destroyed by said bearing face ( 18 ) during the first application of the pad ( 10 ) so as to allow diffusion of the grease ( 32 ) between the application face ( 26 ) of the pad and the bearing face ( 18 ) of the associated caliper ( 12 ).
