Brake Rotor/Disc: Technical Service Bulletins
Pulsation
Brake pulsation concerns may result from two basic conditions:
1.
Thickness variation.
2.
Excessive corrosion.
Rotor thickness variation is the result of uneven rotor wear caused by excessive lateral runout (>0.076 mm; >0.003 in.). Lateral runout can be induced
by:
1.
Distortion of the braking surface by applying uneven and/or excessive wheel nut torque.
(This could be the result of a recent tire change, rotation, etc.).
2.
Improperly refacing rotors.
