Abstract
The present invention concerns a sensor system for monitoring at least the wear of lining material of a disc brake. It may also be used to monitor the stroke of the brake actuator. The sensor system receives signals from a first external and/or internal means and a second sensor means indicative of at least two different conditions of the brake. The major part of the sensor system is received on a cap to be fixed to the caliper and giving a measuring reference. The first means monitors the occurrence of a brake movement. The second sensor means monitors the actual position of a part indicating the wear of the brake lining material and/or the stroke of the brake actuator.
Claims17
A sensor system for monitoring at least the wear of lining material of disc brakes, monitoring the actual position of an adjusting mechanism, a thrust plate or the like as an indication of the wear of the lining material, characterized in that the sensor system is mainly mounted in a way to use a caliper of the disc brake as a measuring reference and that internal and/or external means are arranged indicating at least two different conditions of the brake.
A method of monitoring disc brakes, sensing the position of an adjusting mechanism, a thrust plate or the like, characterized in that the sensed position is used optionally and alternately to measure either the wear of the brake lining material or the stroke of the brake actuation.
