3. Apply compressed air (400 - 800 kPa, 4 - 8 kgf/cm² , 57 - 113 psi) to oil hole (1) at the extreme left and measure movement of second coast brake (Second coast brake) piston.

   If measured value is not within standard range, replace second coast brake plate or second coast brake disc.

   Standard second coast brake piston movement 

   0.75 - 1.35 mm (0.030 - 0.053 in.)

10. Apply compressed air (400 - 800 kPa, 4 - 8 kgf/cm² , 57 - 113 psi) to second hole (1) from the left and measure stroke of second brake (Second brake) piston as shown in figure.

    If measured value is not within standard range, replace second brake plate or second brake disc.

    Standard second brake piston stroke 

    0.97 - 1.70 mm (0.038 - 0.067 in.)
