Inspection

Move brake and clutch pedal pads in the lateral direction with a force of 2 lbs. (10 N) to ensure pedal deflection is in specified range. See «ADJUSTMENT SPECIFICATIONS»(ref-163288-S33905596672004062400000). NOTE: If excessive deflection is noted, replace bushings with NEW ones.
Check position of pedal pad. (Scheme 4) See «ADJUSTMENT SPECIFICATIONS»(ref-163288-S33905596672004062400000).
If it is not in specified value, adjust it by adjusting brake booster operating rod length.

Check bearing axial end play and hub runout before disc rotor runout limit inspection: Moving tire up and down by hand, check that there is no backlash in the bearing, and check that the wheel rotates smoothly. Inspect the lean of axis direction using a dial gauge. Replace the hub bearing if the load range exceeds 0.002" (0.05 mm).
Install disc rotor by tightening 5 wheel nuts.
Set a dial gauge 0.39" (10 mm) inward of rotor outer perimeter. Turn disc rotor to check the runout. If disc rotor runout is above 0.003" (0.075 mm), replace the rotor. (Scheme 5)
Set a micrometer 0.39" (10 mm) inward of the rotor outer perimeter, and then measure disc rotor thickness. see scheme 10 See «DISC BRAKE SPECIFICATIONS»(ref-163288-S41336754872004062400000). If thickness of disc rotor is outside the service limit, replace disc rotor.
