Shoe & Lining Inspection

Inspect linings every 6, 000 miles or 12 months, or whenever wheels are removed. Check both ends of inboard and outboard linings for wear. Replace any that are worn to within 0.030" of rivets on either end of lining on Citation, Omega, Phoenix, and Skylark; 0.032" on Buick, Chevrolet and Pontiac, or to thickness of metal shoe on all other models.
