1986 TOYOTA CAMRY V20 brake

(b) While running in the L range, release the accelerator
pedal and check the engine braking effect.
EVALUATION
If there is no engine braking effect:
wFirst and reverse brake is defective
5. P RANGE TEST
Stop the vehicle on a gradient (more than 5
°) and after
shifting into the P range, release the parking brake.
Then check to see that the parking lock pawl holds the ve-
hicle in place.
4. R RANGE TEST
Shift into the R range and, while starting at full throttle,
check for slipping. 3. L RANGE TEST
(a) While running in the L range, check to see that there
is no up±shift to 2nd gear.
(c) Check for abnormal noise during acceleration
and deceleration.

HINT:
(1) In the 2 and L ranges, ail stages lock±up is OFF.
(2) In the following cases, the lock±up will be released regardless of the lock±up pattern.
When the throttle is completely closed.
When the brake light switch is ON.

COMPONENT PARTS
General Notes
The instructions here are organized so that you work on only one component group at a time.
This will help avoid confusion from similar±looking parts of different subassemblies being on
your work bench at the same time.
The component groups are inspected and repaired from the converter housing side.
As much as possible, complete the inspection, repair and assembly before proceeding to the
next component group. If a component group can not be assembled because parts are being or-
dered, be sure tc keep all parts of that group in a separate container while proceeding with dis-
assembly, inspection, repair and assembly of other component groups.
Recommended fluid for the automatic transaxle is ATF type DEXRON) ll.
GENERAL CLEANING NOTES:
1. All disassembled parts should be washed clean with any fluid passages and holes blown trough wit com-
pressed air.
2. When using compressed air to dry parts, always aim away from yourself to prevent accidentally spraying,
automatic transmission fluid or kerosene in your face.
3. The recommended automatic transaxle fluid or kerosene should be used for cleaning.
PARTS ARRANGEMENT:
1. After cleaning, the parts should be arranged in proper order to allow efficient inspection, repairs, an(
reassembly.
2. When disassembling a valve body, be sure to keep each valve together with the corresponding spring
3. New brakes and clutches that are to be used for replacement must be soaked in transaxle fluid for a least
fifteen minutes before assembly.
GENERAL ASSEMBLY:
1. All oil seal rings, clutch discs, clutch plates, rotating parts, and sliding surfaces should be coated with
transmission fluid prior to reassembly.
2. All gaskets and rubber O±rings should be replaced.
3. Make sure that the ends of a snap ring are not aligned with one of the cutouts and are installed in the
groove correctly.
4. If a worn bushing is to be replaced, the subassembly containing that bushing must be replaced.
5. Check thrust bearings and races for wear or damage. Replace if necessary.
6. Use petroleum jelly to keep parts in place.

ASSEMBLY OF SECOND COAST BRAKE
PISTON
1. SELECT PISTON ROD
If the band is OK with piston stroke not within the standard value,
select the piston rod.
Piston stroke: 1.5 ± 3.0 mm (0.059 ± 0.118 in.)
There are two lengths of piston rod.
Piston rod length: 72.9 mm (2.870 in.)
71.4 mm (2.811 in.)
2. INSTALL PISTON ROD
(a) Install the washer and spring to the piston rod.
INSPECTION OF SECOND COAST BRAKE
COMPONENT
INSPECT BRAKE BAND
If the lining of the brake band is exfoliated or discolored,
or even part of the printed numbers are defaced, replace the
brake band.(b) Remove the spring, washer and piston rod.
(b) Install an E±ring while pushing the piston.

(b) Using SST, measure the piston stroke applying and re-
leasing the compressed air (4 ± 8 kg/cm2, 57 ± 114
psi or 392 ± 785 kPa) as shown.
SST 09240±00020
