Sentra Wagon L4-1597cc 1.6L SOHC (E16S) (1986)
Possible Cause of Brake Judder/Steering Wheel Shimmy
A brake judder/steering wheel shimmy incident may develop in any vehicle if the following series of events occur:
^
The brake rotor run-out exceeds specification limits.
^
As the brake pad rubs against the rotor while driving, the high spots on the brake rotor wear slightly.
^
Rotor thickness variation may develop as the high spots on the brake rotor wear. If this thickness variation becomes large enough, brake
judder/shimmy may occur.
Service Procedure
Resurfacing the brake rotor using the Ammco On-Car Brake Lathe is the preferred method of correcting excessive rotor run-out and thickness variation.
Refer to Nissan Technical Bulletin NTB92-062a (BR92-004a) "Ammco On-Car Brake Lathe Operating Guidelines."
