21. CHECK PISTON STROKE OF OVERDRIVE BRAKE
(a) Place SST and a dial indicator onto the overdrive brake as shown in the figure.
SST 09350-30020 (09350-06120)
(b) Measure the stroke applying and releasing the compressed air (4 — 8 kgf/cm², 57-114 psi or 392 — 785 kPa) as shown in the figure.
Piston stroke:
7M-GE 1.40 — 1.70 mm (0.0551 — 0.0669 in.)
7M-GTE 1.75 — 2.05 mm (0.0689 — 0.0807 in.)
If the values are nonstandard, inspect the discs. (See page AT-80)
22. REMOVE FLANGES, PLATES AND DISCS OF OVERDRIVE BRAKE
(a) Remove the snap ring.
(b) Remove the flanges, plates and discs as a set.
7M-GE: Two flanges, three plates and four discs
7M-GTE: Two flanges, four plates and five discs
The method of inspection, refer to AT-80.
For 7M-GTE
23. CHECK PISTON ROD STROKE OF SECOND COAST BRAKE
(a) Place a mark on the second coast brake piston rod as shown in the figure.
