SECOND BRAKE
COMPONENTS
SECOND BRAKE DISASSEMBLY
1. CHECK SECOND BRAKE PISTON MOVEMENT
Make sure the second brake piston moves smoothly while
applying and releasing low-pressure compressed air to
the second brake drum.
2. REMOVE PISTON RETURN SPRING
(a) Places SST on the spring retainer, and compress the re-
turn spring with a shop press.
SST 09350-30020 (09350-07040)
(b) Using SST, remove the snap ring.

(c) Remove the spring retainer and piston return spring.
3. REMOVE SECOND BRAKE PISTON
(a) Hold the second brake piston with hand apply com-
pressed air to the second brake drum to remove the se-
cond brake piston.
(b) Remove the second brake piston.
HINT: If the piston is at an angle and cannot be removed,
press down on the side jutting out and again apply com-
pressed air, or else wind vinyl tape around the piston end
and remove it with needle nose pliers.
(c) Remove the 2 O-rings from the piston.
SECOND BRAKE INSPECTION
1. INSPECT DISC, PLATE AND FLANGE
Check to see if the sliding surface of the disc, plate and
flange are worn or burnt.
If necessary, replace them.
HINT:
If the lining of the disc is peeling off or discolored, or
even if a part of the printed numbers are defaced, re-
place all discs.
Before assembling new discs, soak them in ATF for
at least 15 minutes.
2. CHECK PISTON RETURN SPRING
Check the return spring free length together with the
spring test.
Standard free length:
19.64 mm (0.7732 in.)

SECOND BRAKE ASSEMBLY
1. INSTALL SECOND BRAKE PISTON
(a) Coat 2 new O-rings with ATF and install them on second
brake piston.
(b) Being careful not to damage the O-rings, press the se-
cond brake piston into the second brake drum with both
hands.
2. INSTALL PISTON RETURN SPRINGS
(a) Install the piston return spring.
(b) Install the spring retainer.
(c) Place SST on the spring retainer, and compress the re-
turn spring with a shop press.
SST 09350-30020 (09350-07040)
(d) Using SST, install the snap ring.

3. CHECK SECOND BRAKE PISTON MOVEMENT
Make sure the second brake piston moves smoothly
when applying and releasing low-pressure compressed
air to the second brake drum.

REAR PLANETARY GEAR INSPECTION
MEASURE PLANETARY PINION GEAR THRUST
CLEARANCE
Using a feeler gauge, measure the planetary pinion gear
thrust clearance.
Standard clearance:
0.2-0.6 mm (0.008-0.024 in.)
Maximum clearance:
1.0 mm (0.039 in.)
If the clearance is greater than the maximum, replace the
planetary gear assembly.

2. INSTALL NO.2 THRUST WASHER
(a) Coat the thrust washer with petroleum jelly.
(b) Install the thrust washer onto the rear planetary gear.
HINT: Make sure that the lug shapes match the cutout
portions on the rear planetary gear.
3. INSTALL NO.2 ONE-WAY CLUTCH
(a) Install the one-way clutch and 2 retainers into the rear
planetary gear, as shown.
HINT: Make sure that the open ends of the guides on the
one-way clutch face upward.
