- 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).
- Examples of measurements within specifications.
- 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).
- 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).
- Examples of measurements out of specifications.
- 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.
- 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).
- If measurement does not meet specification, remove caliper from machine.
- Release pressure from caliper.
- 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.
