Challenger V8-5.7L (2010)
Most minimum thickness specifications (1) are cast into the rotor's unmachined surface (2). Some brake rotors have the minimum thickness specification
located elsewhere. Refer to the following paragraph. Limits can also be found in this component's specification table See: Specifications
.
The minimum thickness specification is stamped into the outer diameter edge (1) (along vented end) of the disc.
ROTOR THICKNESS VARIATION
Thickness variation in a rotor's braking surface can result in pedal pulsation, chatter and surge. This can also be caused by excessive runout in the rotor
or the hub.
Rotor thickness variation measurements should be made in conjunction with measuring runout. Measure thickness of the brake rotor (2) at 12 equal
points around the rotor braking surface with a micrometer (1) at a radius approximately 25 mm (1 inch) from edge of rotor. If thickness measurements
vary beyond the specification listed in the specification table See: Specifications , the rotor should be refaced or replaced. See: Service and
Repair/Procedures.
