BRAKE VIBRATION AND/OR PULSATIONPage 4 of 6
3) Advantages Of Using An On±Car Brake Lathe
Toyota Motor Corporation Engineers strongly recommend that an on±car brake lathe be used
for repairing brake vibration and pulsation. This method improves rotor and hub combined
runout, and is the preferred method when compared to rotor replacement and off±the±car rotor
machining.
A. Technical Advantage of Caliper Mounted Brake Lathe
± Installing the brake lathe in the same position as the caliper results in minimal runout
relative to the caliper.
± Eliminating this runout minimizes the pad grinding on the rotor and reduces rotor
thickness variation.
B. Practical Use Benefits
± Resurfacing rotors on vehicles with rotor/hub assemblies can be performed easily.
± Vehicles with corrosion between hub and rotor flanges can be machined without
removing rotor from hub.
4) Rotor Replacement And Off±Car Brake Lathe Procedures
If an on±car brake lathe is not available at your dealership, it may be necessary to use an off±car
lathe or replace rotors. In order to ensure proper brake vibration and pulsation repairs, pay close
attention to the following precautions:
A. Off±Car Brake Lathe Precautions
± Perform routine maintenance of brake lathe components (clearance of arbor shaft to
adapters may need to be repaired).
± Clean all adapters and shaft to maintain accuracy of equipment.
± When installing rotor to machine, clean mud, rust, and/or foreign material from the
adapters and rotors.
± After installing rotor on machine, check rotor runout using dial indicator. If runout is
excessive, determine the cause and correct it.
± Follow lathe manufacturer repair procedures. Do not cut excessive amounts off rotor
during the first cut to save time.
Anytime a rotor is machined it must be measured for minimum rotor thickness. The
thickness for the rotor is never to be less than minimum thickness as specified in the
appropriate repair manual.

The information updated in this TSB is red
and underlined.
Under certain driving conditions, some 1MZ±FE equipped 1997 ± 1999 Camry California
Emission specification vehicles can exhibit a M.I.L. ªONº DTC P1133. An improved
Air/Fuel Ratio Sensor has been developed to correct this condition.

Should a M.I.L. ªONº condition with DTC P1133 be encountered, perform diagnostic
procedures as described in the Repair Manual.
If the problem source cannot be identified after checking all affected areas according
to the Repair Manual, the cause may be an Air/Fuel Ratio Sensor malfunction. In this
case, replace the Air/Fuel Ratio Sensor with the current part number listed above.
If the Exhaust Manifold threads are damaged by removal of the sensor, they can be
repaired by the proper use of a M18 x 1.5 tap.
