A friction lining warning device for a pin-guided spot-type disc brake whose caliper housing, brake carrier is slidingly arranged at a pin. A stud which engages an opening of the pin and is arranged in alignment with the pin. A switch housing surrounds the pin and is connected to the caliper housing, to the brake carrier, the pin and the stud and is movable relative to the switch housing and to the caliper housing. Electric switches in the stud, in the switch housing release when the stud has travelled a predetermined distance relative to the switch housing. The switch housing and the stud can be brought in abutment with each other to provide a basic adjustment. The switch housing is connectable to the caliper housing, brake carrier within a range of tolerance after the basic adjustment has been assumed. The stud (19, 61, 62, 91, 101, 102, 121, 141, 190, 201) is provided with a stop (29, 105) which abuts against the pin (4) in the axial direction.
A friction lining warning device for a pin-guided spot-type disc brake whose caliper housing is slidingly arranged at a pin, with a stud which engages an opening of said pin and is arranged in alignment with the latter, with a switch housing which surrounds said pin and which is connected to said caliper housing, said pin and said stud being movable relative to said switch housing and to said caliper housing, and with electric switches adjacent said stud in said switch housing which release when said stud has travelled a predetermined distance in respect to said switch housing, said switch housing and said stud in abutment with each other and providing a basic adjustment and said switch housing being connectable to said caliper housing within a range of tolerance after said basic adjustment has been provided, wherein said stud (19, 61, 91, 101, 102, 121, 141, 190, 201) presents a stop (29, 105) which is axially abuttable with said pin (4) and means for indicating that a warning state has been detected.
A friction lining warning device for a spot-type disc brake slidingly arranged on a pin, with an axially extending stud presenting a front surface and with a bushing surrounding said stud and presenting an internal bottom surface which are movable relative to each other, wherein said front surface (20, 68) of said stud (19, 61, 62, 91, 101, 102, 121, 141, 190, 201) is abuttable against said bottom surface (21) and means for indicating that a warning state has been detected including electric switches mounted in said bushing adjacent said stud, and wherein said stud provides a stop which is axially abuttable with said pin.
