Abstract
A wear indicator comprising: (a) a connector that attaches the wear indicator to a brake pad, the brake pad including a friction material having a plane; (b) a scraper; and (c) an indicator portion; wherein the indicator portion forms a cantilever connection with the scraper and extends parallel to the plane of the friction portion.
Claims18
A wear indicator comprising:
- a. a connector that attaches the wear indicator to a brake pad, the brake pad including a friction material having a plane;
- b. a scraper configured to contact a rotor in a brake system;
- and
- c. an indicator portion;
- wherein the indicator portion forms a cantilever connection with the scraper and extends parallel to the plane of the friction material;
- and
- wherein the indicator portion includes an indicator body and the indicator body is generally hour glass shaped.

A wear indicator comprising:
- a. a connector that attaches the wear indicator to a brake pad, the brake pad including a friction material having a plane;
- b. a scraper configured to contract a rotor in a brake system;
- and
- c. an indicator portion;
- wherein the indicator portion forms a cantilever connection with the scraper and extends parallel to the plane of the friction material;

A wear indicator comprising:
- a. a connector that attaches the wear indicator to a pressure plate of a brake member;
- b. a scraper configured to contact a rotor in a brake system that extends from the pressure plate of the brake member over a friction material so that when a predetermined amount of the friction material is removed the scraper assists in creating an indication;
- and
- c. an indicator portion that works in conjunction with the scraper to create the indication;
- wherein the scraper is located between the connector and the indicator portion;
- and
- wherein the indicator portion is generally planar and is free of any bends having an angle of 45 degrees or more.
4 more elements
A brake system comprising:
- a. a rotor having a pair of opposing faces defining a plane;
- b. one or more brake members comprising:
- i. a pressure plate and
- ii. a friction material having a plane that extends along a longitudinal axis;
- wherein one of the one or more brake members extends on each side of the rotor;
- c. one or more wear indicators comprising:
- i. a connector for attaching the one or more wear indicators to the pressure plate of the one or more brake members;
- ii. a scraper configured to contact the rotor that extends over the friction material so that when an amount of friction material is removed the scraper extends beyond the friction material creating a sound;
- and
- iii. an indicator portion that extends along the pressure plate;
- wherein the indicator portion forms a cantilever connection with the scraper and extends parallel to the plane of the friction material;
- and
- wherein the shape of the wear indicator substantially follows one or more contours of the pressure plate;
- and
- wherein the indicator portion includes an indicator body attached to and extending from the scraper and the indicator body extends from the scraper in a direction of rotation of the rotor.
