Abstract
A vehicle braking member has a block of friction material cooperating in sliding manner with a respective member for braking, and supports a wear detector wherein a resistive element, consumed simultaneously with the block of friction material, has a first electric terminal set, in use, to a reference potential, and a single second electric terminal cooperating in sliding manner with the member for braking so as to be set to the same potential as the member for braking.
Claims7
A wear detector for a vehicle braking member having a block of friction material for cooperating in sliding manner with a respective metal body, comprising:
- a) an elongated resistive element for being consumed simultaneously with the block;
- b) said resistive element including a first electric terminal set, in use, to a reference potential, and a second electric terminal for cooperating in sliding manner with the metal body so as to make electrical contact with the metal body and be set to the same potential as the metal body, such that changes to the electric resistance of said element as it is consumed during use determines the thickness of the block;
- and
- c) a supporting body having an external groove to at least partly house said resistive element in a given initial configuration and at least one retaining element to maintain said resistive element in a fixed position inside said groove.
