Question

technician a says that if a brake pulsation does not happen right away, that means the lro is perfect. technician b says that the low spot of rotor, rubs the pad and transfers material every revolution. who is correct? technician a technician b both technician a and technician b neither technician a nor technician b

Explanation:

A lack of immediate brake pulsation doesn't guarantee perfect LRO (Lateral Run - Out). The low spot on the rotor can rub the pad and transfer material each revolution, which is a correct statement about brake rotor - pad interaction.
