Brakes -Brake mechanics 911 Carrera (996) 6. If the brake disc lateral runout exceeds 8. Wheel hub lateral runout is too large: 0.06 mm, remove the brake disc and check Replacethe wheel hub. the wheel hub lateral runout. First mark Wheel hub lateral runout OK: the position with respect to the wheel hub. Cleanthe levellingand centring surfaces on the brake disc and wheel hub. Next, apply a thin coat of Optimoly TA to the centring 7. Check the wheel hub lateral runout as surface on the wheel hub. described below: Fastenbrake disc on the wheel hub in Measure1 x outside (arrow) and 1 x inside a different position than before -radially (arrow) of the wheel bolt area (5-point offset with respect to the wheel hub. measuring procedure) on the front face Repeatmeasurementwith fitted adapter plate of the whee! hub.
