Disc Plate Thickness Inspection

WARNING: This page is about a different car, the 2017 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

Excessive runout may result if the disc plate is removed from the vehicle then machined. Machine the disc plate while installed on the vehicle.

Remove the wheel and tire. (See WHEEL AND TIRE REMOVAL/INSTALLATION .)
Measure the thickness of the disc plate.
Minimum rear disc plate thickness

7.0 mm {0.28 in}

Minimum rear disc plate thickness after machining using a brake lathe on-vehicle

- If the thickness is not within the specification, replace the disc plate. (See REAR BRAKE (DISC) REMOVAL/INSTALLATION .)
