A brake adjustment monitoring device of use on motor vehicles to warn the operators when the brakes are in need of adjustment or repair. A magnet is adjustably secured to the brake shaft connected to an existing brake air chamber assembly. A magnetically sensitive switch which is electrically connected to a wear signaling device is mounted on a rod proximate to the brake shaft at a predetermined distance from the magnet, so as to close the switch by magnetic flux when the shaft of the air chamber moves outward too far after the operator touches the brake pedal of the vehicle. The switch when closed energizes the wear signaling device, such as a buzzer and bulb, to alert the operator that the brakes are in need of adjustment. The improved device includes a sliding magnet--switch spacing gauge, which presets the predetermined distance that the magnet, which is mounted to move with the brake shaft, travels before it reaches the magnetically sensitive switch to close the switch and energize the wear signaling device. An interlocking spacing gauge is provided to quickly set the position of the mounting plate and rod holding the switch--housing block combination, with respect to the magnet. The magnet and block combination is formed with a plurality of openings through the body of the block and with a removable wedge piece to permit mounting of the magnet housing block combination at various positions along the brake shaft or yoke.
