3. Use Tooling (B) to measure distance (X) and distance (Y) .

4. The measurements are taken from the brake caliper linings (7) to the rotor (9) on both sides of the rotor. Measurements (X) and (Y) must be 1.50 ± 0.50 mm (0.06 ± 0.029 inch). Measurements (X) and (Y) must be equal within 0.20 mm (0.01 inch).

5. Examples of measurements within specifications.

   1. Measurement (X) equals 1.40 mm (0.055 inch) and measurement (Y) equals 1.60 mm (0.063 inch). Both linings are within 1.50 ± 0.50 mm (0.06 ± 0.029 inch).

   2. Measurement (Y) 1.60 mm (0.063 inch) minus measurement (X) 1.40 mm (0.055 inch) is within 0.20 mm (0.01 inch).

6. Examples of measurements out of specifications.

   1. Measurement (X) equals 2.05 mm (0.08 inch) and measurement (Y) equals 0.95 mm (0.04 inch). Neither lining is within 1.50 ± 0.50 mm (0.06 ± 0.029 inch) of the rotor.

   2. Measurement (Y) 2.05 mm (0.08 inch) minus measurement (X) 0.95 mm (0.04 inch) is not within 0.20 mm (0.01 inch).

7. If measurement does not meet specification, remove caliper from machine.

8. Release pressure from caliper.

9. Use Tooling (A) to turn each spring retaining cap. On the side with lining too far from rotor, turn spring retaining cap (11) a 1/4 turn clockwise. On the side with lining too close to rotor, turn spring retaining cap (11) a 1/4 turn counterclockwise.

   Note: a 1/4 turn will move the brake lining 0.15 mm (0.06 inch). Do not turn either spring retaining cap (11) more than 3/4 turn clockwise or counterclockwise.

10. Pressurize parking brake to 100 bar (1450 psi) with Tooling (C) .
