Thickness
ℹ️ Minimum allowed thickness of the brake disc is 2.5 mm ⚠️ If the thickness is below the specified limit - replace the brake disc
Grooving
ℹ️ The surfaces of the brake disc must be smooth and without deep grooves ⚠️ If there is significant grooving on the brake disc surfaces - replace the brake disc
Straightness
ℹ️ The brake disc must run true when spinning the wheel ⚠️ If the brake disc appears warped - measure the axial runout at the very edge of the brake disc with a dial indicator (runout must be under 0.3 mm) ⚠️ If the brake disc axial runout exceeds the specified limit - the corner / motor bearing must be reinstalled to achieve correct alignment with the brake disc
