PULSER (RELUCTOR Ring)

Check front and rear pulser for chipped or damaged teeth. Measure air gap between wheel sensor and pulser while rotating pulser. Gap should be .02-.04" (.4-1.0 mm). If gap exceeds .04" (1.0 mm), check for a distorted knuckle. To inspect rear wheel sensor air gap, remove rear brake. See WHEEL SENSOR  under REMOVAL & INSTALLATION.
