Note:
Brake rotor thickness variation MUST be checked BEFOREchecking for assembled lateral runout (LRO). Thickness variationexceeding the maximum acceptable level can cause brake pulsation.Refer toBrake Rotor Thickness Variation Measurement.Brake rotor assembled lateral runout (LRO) exceeding themaximum allowable specification can cause thickness variation todevelop in the brake rotor over time, usually between 4800–11 300-km(3,000–7,000-mi). Refer toBrake Rotor Assembled Lateral Runout Measurement.Review the following acceptable methods for bringing thebrake rotor assembled LRO to within specifications. Determine whichmethod to use for the specific vehicle being repaired.
The correction plate method of correcting assembled LROinvolves the addition of a tapered plate between the brake rotorand the hub/axle flange. The correction plate method can be used tocorrect LRO that exceeds the specification by up to0.23-mm (0.009-in). Refer toBrake Rotor Assembled Lateral Runout Correction - Correction Plates.The on-vehicle brake lathe method is used to bring the LRO towithin specifications through compensating for LRO whilerefinishing the brake rotor. Refer toBrake Rotor Assembled Lateral Runout Correction - On Vehicle Lathe.If the assembled LRO cannot be corrected using these methods,then other components must be suspected as causing and/orcontributing to the LRO concern.
Child Restraint Systems
Rear-Facing Infant Restraint
A rear-facing child restraint provides
restraint with the seating surface
against the back of the infant.
The harness system holds the infant
in place and, in a crash, acts to
keep the infant positioned in the
restraint.
Forward-Facing Child Restraint
