If any of the measurements exceed the brake disc thickness variation specification, a new brake disc must be installed and the brake disc runout re-checked.
如果有任何测量值超过制动盘厚度变量规格时，则必须安装新的制动盘并且重新检查制动盘的失圆。
Fit the dial gauge with some preload and measure the lateral runout at the greatest external diameter of the brake disc.
在带有一定预载的情况下安装百分表，然后测量制动盘最大外径处的横向跳动。
