Abstract
The invention relates to a pad for a bicycle disc brake, comprising a support frame and an element made of friction-wearing material associated with said support frame. The element made of friction-wearing material comprises a visual wearing indicator, which preferably is defined on an upper portion of the element made of friction-wearing material, more preferably at a side end area of said upper portion. The invention also relates to a bicycle disc brake comprising a pair of pads of the type described above.

A pad for a bicycle disc brake, comprising a support frame and an element made of friction-wearing material associated with said support frame, wherein the element made of friction-wearing material has a rear surface connected to the support frame, an upper surface, a lower surface, two opposite side surfaces between the upper and lower surface, a front surface that is opposite to the rear surface and defines a wear surface of the element made of friction-wearing material, and a visual wearing indicator that defines in the element made of friction-wearing material a step interposed between the upper surface and one of the two opposite side surfaces, and that comprises an inclined surface connecting the upper surface to said one of the two opposite side surfaces.
A pad for a bicycle disc brake, comprising a support frame and an element made of friction-wearing material associated with said support frame, wherein the element made of friction-wearing material has a visual wearing indicator in said friction-wearing material that is visible prior to any wearing of the friction-wearing material,
- wherein the element made of friction-wearing material has a predetermined thickness and a recess in said predetermined thickness that defines the visual wearing indicator;
- wherein said recess comprises two substantially perpendicular surfaces, a first surface of said two surfaces defining, in said element made of friction-wearing material, an area of reduced thickness with respect to said predetermined thickness and a second surface of said two surfaces having a height equal to the difference between said predetermined thickness and said reduced thickness, wherein the visual wearing indicator is defined by said second surface, wherein the element made of friction-wearing material comprises an upper surface, a lower surface and two opposite side surfaces, wherein said second surface is an inclined surface that connects said upper surface and one of said side surfaces.
A bicycle disc brake pad comprising:
- a support frame;
- a friction-wearing element mounted on said support frame, the friction-wearing element has a front surface, an upper surface, a lower surface substantially perpendicular to the front surface, and two opposite side surfaces;
- wherein said friction-wearing element has a visual wearing indicator defined by a step positioned in the front surface at a location where a first portion of said upper surface joins with one of said side surfaces;
- and
- wherein the front surface directly joins a second portion of said upper surface with the lower surface.
A bicycle disc brake pad, comprising:
- a support frame;
- a friction-wearing element mounted on said support frame and having a rear surface connected to the support frame, an upper surface, a lower surface, two opposite side surfaces, and a front surface opposite to the rear surface and continuous between the two opposite side surfaces and defining a wear surface;
- a visual wearing indicator in the friction-wearing element;
- the visual wearing indicator being a recess surface obtained in the front surface by partial removal of material, wherein said recess surface is an inclined surface that is interposed between the upper surface and one of the opposite side surfaces and that connects said upper surface and said one of the opposite side surfaces.
