ISSUE:
Early replacement of the brake components, rotors and pads due to brake roughness concern, is lowering customer's view of quality. The cause of brake
roughness is due to small changes in braking torque when the brake is applied. The following are the major reasons for the brake torque variation:
^
Runout of disc rotor
^
Rusted rotor surface
^
Warped rotor due to improper wheel lug nut tightening (torque too high or uneven)
^
Varied rotor thickness around the disk
^
Transferred patches of lining material on the rotor surface
^
Uneven tire wear and balance
ACTION:
Diagnose brake roughness by referring to the following procedure for service details.
SERVICE PROCEDURE/DIAGNOSIS STEPS
NOTE:
BEGIN WITH STEP 1 AND FINISH WITH STEP 6.
1.
Check the Condition of Tires and Their Balance
Sometimes the brake roughness concern is not brake roughness at all. In fact, some complaints are due to the out-of-round and out-of-balance tires or
broken steel cord (for steel belted radial tires) in the tires. The effects of these problems show up at all conditions of driving, but may seem worse when
