The total should be 0.26 - 0.60 mm (0.010 - 0.024 inch).

- If the total clearance between the caliper and the steering knuckle is less than 0.26 mm (0.010 inch), file the steering knuckle equally on each side until the proper clearance is obtained.
- If the total clearance between the caliper and the steering knuckle is more than 0.60 mm (0.024 inch), inspect the brake caliper and the steering knuckle for damage and replace as needed.

9. Install the tire and wheel.
