Brake Disc wear and criticalities
Periodical inspection of the bearings and their replacement is an essential operation for proper maintenance of the vehicle: a wheel bearing with defects creates greater friction, which is the cause of noise associated with a serious problem. A defective bearing also creates issues for correct operation of the hub, shock absorber and all related parts, causing premature wear.
It is good practice to check the condition of the wheel bearing when the brakes are replaced and when dealing with noise and early onset of wear.
Deterioration of the wheel bearing can be caused by high mileage, accidental impact or incorrect assembly.
