(a) Apply compressed air (392 kPa, 4.0 kgf/cm
2, 57 psi) to the
transaxle case to remove 1st & reverse brake piston.
NOTICE:
SBlowing off the air may cause the piston to jump−out.
When removing the piston, hold it by your hand using
a waste cloth.
STake care not to splash ATF when air−blowing.
(b) Remove the 2 O−rings from the 1st & reverse brake pis-
ton.
