Montero Sport V6-3.5L SOHC (2004)
1. Remove dirt and rust from the brake disc surface.
2. Measure the disc thickness at four positions or more.
Standard value: 18.0 mm (0.71 inch)
Minimum limit: 16.4 mm (0.65 inch)
3. Thickness variation (at least 4 positions) should not be more than 0.015 mm (0.0006 inch).
CAUTION:
^
After a new brake disc is installed, always grind the brake disc with on-the-car type brake lathe. If this step is not carried out, the brake disc
run-out exceeds the specified value, resulting in judder.
^
When the on-the-car type lathe is used, first install M12 flat washer on the stud bolt in the brake disc side according to the figure, and then
install the adapter. If the adapter is installed with M12 flat washer not seated, the brake disc rotor may be deformed, resulting in inaccurate
grinding. Grind the brake disc with all wheel nuts diagonally and equally tightened to the specified torque 100 Nm (74 ft. lbs.). When all
numbers of wheel nuts are not used, or the tightening torque is excessive or not equal, the brake disc rotor or drum may be deformed, resulting
in judder.
4. If the disc is less than 8.4 mm (0.33 inch) thick, replace it with a new one. If thickness variation exceeds the specification, turn rotor with an
on-the-car brake lathe ("Accuturn-8750" or equivalent).
If the calculated final thickness is less than the standard value, replace the disc.
