Document Type and Number:
Japanese Patent JPH0222250
Kind Code:
B2
Abstract:
The brake has a rotary member, such as a brake disc or a brake drum, clamped from both sides by a pair of main and follower brake linings to apply brake. One of the ends of a detection rod (32) is fitted to an armature of a magnet which drives the main brake lining of the brake. A detection metal (34) is fitted to the other end of the detection rod. The brake includes a switch (45) for detecting the movement of a lever (38) fitted rotatably to a fitting base (33) to which the follower brake lining is fitted. This occurs when a step portion (34a) of the detection metal meshes with a step portion (37a) of a detection piece (37) fitted to the tip of the lever because the magnet stroke becomes large due to the wear of the brake linings. Members bring the follower brake lining close to the main brake lining by a predetermined stroke by the operation of the switch.
