ABSTRACT:
A method and apparatus for monitoring slack adjustment for braking in a vehicle is applicable to either drum or disc brake assemblies. The vehicle has several axle assemblies each with a pair of brake assemblies. A typical disc brake assembly includes a rotating disc, an actuator, a caliper with a brake lining supported on a backing plate, and a slack adjuster for adjusting the travel distance of the caliper to the disc. The actuator moves the brake linings of the caliper into contact with the rotating disc to brake the vehicle, resulting in a temperature increase in the brake linings. Temperature sensors are embedded in the brake linings of each brake assembly on each axle of the vehicle. The temperature of each brake lining is measured and compared with the temperature of the brake lining of its brake pair on the same axle. If the ratio of the two brake lining temperatures achieves a predetermined limit, a slack adjuster is deemed out of adjustment and a warning signal is sent to the vehicle operator.
