DISC ROTOR INSPECTION

Visual 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 dial gauge. [Measured at 10 mm (0.39 in) inside disc edge.]
Runout limit: 0.055 mm (0.0022 in)
(With it attached to the vehicle)

NOTE: Before measuring, make sure that wheel bearing axial end play is within the specification. Refer to RAX-5, "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-PFM 90.5) or equivalent.]

Thickness Inspection





Check the thickness of the disc rotor using a micrometer. Replace disc rotor if the thickness is under the wear limit.
Standard thickness: 16.0 mm (0.631 in)
Wear limit: 14.0 mm (0.551 in)
Thickness variation (Measured at 8 positions): 0.015 mm (0.0006in)
