DISC ROTOR INSPECTIONVisual Inspection
Check surface of disc rotor for uneven wear, cracks, and serious damage. Replace if there are.
Runout Inspection
1. Fix disc rotor to wheel hub using wheel nuts (2 or more positions).
2. Inspect runout using a dial gauge. [Measured at 10 mm (0.39 in) inside the disc edge.]
Runout limit: 0.035 mm (0.0014 in) (with it attached to the vehicle)
NOTE: Before measuring, make sure that wheel bearing axial end play is within the specification. Refer to FAX-6, "On-Vehicle Inspection".
3. When runout exceeds limit value, displace mounting positions of disc rotor by one hole. And then find a position of the minimum value for runout.
4. Replace or lathe disc rotor if runout is outside the limit even after performing the above operation. [When lathing, use the Pro-Cut PFM On-Car Brake Lathe (Tool No. 38-PFM90.5) or equivalent.]
Thickness Inspection
Check thickness of the disc rotor using a micrometer. Replace disc rotor if thickness is under the wear limit.
Standard thickness: 28.0 mm (1.102 in)
Wear limit: 26.0 mm (1.024 in)
Thickness variation (Measured at 8 positions): 0.015 mm (0.0006 in)
