5.
Measure the master cylinder inside diameter and the piston outside diameter with a cylinder gauge micrometer.
note
Measure the inside diameter of the master cylinder at three places (bottom, middle, and top) in a perpendicular direction.
Check the inside of the cylinder body for rust, pitting or scoring.
Check the piston cup for wear or distortion.
Check the piston for rust, pitting or scoring.
Check the clutch tube line for clogged.
Measure the master cylinder inside diameter and the piston outside diameter with a cylinder gauge micrometer.
Measure the inside diameter of the master cylinder at three places (bottom, middle, and top) in a perpendicular direction.
If the master cylinder-to-piston clearance exceeds the limit, replace the master cylinder and/or piston assembly.
Limit: 0.15 mm (0.006 in.)
