I haven't had to touch the brakes on the 93 Accord I picked up last fall, so I'm not exactly sure that they work the same as others I've worked on. But here are some things to check based on my experience with other cars. A square toothed ring rotates with the axle. A magnetic sensor reads the teeth to tell the rotation speed. The ring can crack and open up, creating a larger gap between teeth that confuses the sensor. A tooth can also be broken off. The sensor, because it is magnetized, can get a buildup of metal dust and shavings on it, causing it to not read correctly. These are the simple things from a visual inspection. Most other problems need to be diagnosed with a brake scan tool.
