43) Measure O/D and 2nd coast brake piston stroke.
• Measure dimension "a" from end face of transaxle case to O/
D and 2nd coast brake rear plate (1) using straightedge and
micrometer caliper.
• Measure dimension "b" from O/D and 2nd coast brake piston
(2) to rear cover assembly mating surface using straightedge
and micrometer caliper.
• Calculate piston stroke from measured value of dimensions
"a" and "b".
• Piston stroke = "a" – "b"
O/D and 2nd coast brake piston stroke
standard: 0.65 – 1.05 mm (0.026 – 0.041 in.)
When piston stroke is out of specification, select O/D and 2nd
coast brake rear plate with proper thickness from among the list
below and replace it.
