Abstract
A lining wear warning device for a brake shoe lining rotatable member pivotally supported on a non-rotatable member so as to be engaged with a brake shoe carrying a brake lining is pivotally moved when the brake shoe is actuated; means arranged on the non-rotatable member in engagement with the rotatable member permits the movement of rotatable member during the braking operation and prevents the movement in the reverse direction when the brake is released; and an electric switch operative in response to a predetermined amount of relative movement between the rotatable and non-rotatable members closes a warning circuit, the relative movement between the rotatable and non-rotatable members being proportional to an amount of lining wear.
