Measuring Brake Disc Lateral Runout
WARNING: This page is about a different car, the 2004 Volvo S40, 2003 Volvo S40, 2002 Volvo S40, 2001 Volvo S40, and 2000 Volvo S40. However, it is still accessible from the selected car via links, so may be relevant.
Assemble the dial indicator ( 9999696 , 9999684 ) and position it against the brake disc.
Slowly rotate the hub using a socket wrench. Maximum permissible lateral runout on the outside of the hub rear/front is 0.07 mm.
If the maximum lateral runout is exceeded, the disc must be replaced or turned down (if tools are available for such).
NOTE:
This lateral runout can also be caused by the hub's lateral runout. Check hub lateral runout as necessary. See Measuring lateral runout in hub (front/rear) .
Work element during replacement as described in Front Brake Disc Replacement (front) or Replacement Of Rear Brake Disc (rear).
