REMOVAL
WAR NING :
Clean brakes with a vacuum dust collector to minimize the hazard of air borne particles or other mate-
rials.
CAUTION:
Clean dust on disc rotor and back plate using a vacuum dust collector. Do not blow with com-
pressed air.
Put matching marks on both disc rotor and wheel hub when removing disc rotor.

a. Secure the disc rotor in place with wheel nuts and remove adjuster hole plug.
b. Using a flat-bladed screwdriver, rotate adjuster in direction “B” to
retract and loosen brake shoe.
4. Remove anti-rattle pins, retainers, anti-rattle springs, and return
springs.
5. Remove parking brake shoes, adjuster assembly, and toggle
lever.
6. About the removal of back plate, refer to RAX-9, "
Disassembly
and Assembly" .

–Anti-rattle pin for excessive wear and corrosion.
–Return spring for sagging.
Make sure that adjuster moves smoothly.
Visually check the inside of drum for excessive wear, cracks, and damage. Check the inside of drum using
a pair of vernier calipers.
Replace with new part if the above part is malfunction.
INSTALLATION
Note the following, and install in the reverse order of removal.
Refer to PB-5, "Components" and apply PBC (Poly Butyl Cupry-
sil) grease or equivalent to the specified points during assembly.
Assemble adjusters so that threaded part is expanded when
rotating it in the direction shown by arrow.
Shorten adjuster by rotating it.
Check shoe sliding surface and drum inner surface for grease.
Wipe it off if it adhere on the surfaces.
Perform break-in operation as follows after replacing brake
shoes or disc rotors, or if brakes do not function well.
1. Adjust parking brake pedal stroke to the specified amount. Refer
to PB-2, "
ADJUSTMENT" .
2. Perform parking brake break-in (drag run) operation by driving vehicle under the following conditions:
3. Check parking brake pedal stroke of parking brake. Adjust again if it is outside the standard. Drive forward
Vehicle speed: Approx. 40 km/h (25 MPH) set (constant and forward)
Parking brake operating force: Approx. 400 N (40 kg, 88 lb) set constant
Time: Approx. 10 sec.

PDU (POWER DISTRIBUTION UNIT)PFP:285F1
Component Parts and Harness Connector LocationNKS004ED
System DescriptionNKS004EE
PDU (Power Distribution Unit) is the unit that executes the power distribution with the control signal from
the Intelligent Key unit, instead of the mechanical power supply mechanism by conventional key cylinder.
The push-button ignition switch is operable when the Intelligent Key is within the detention area of the
interior antenna or is inserted to the key slot.
The push-button ignition switch operation is input to the Intelligent Key unit as a request signal. Then, the
Intelligent Key unit processes the request signal and orders the PDU to switch into the appropriate power
supply position.
NOTE:
The prerequisite for starting the engine varies by the state of brake pedal, A/T selector lever, and vehicle
speed.
PDU distributes power to each power supply circuit according to the request signal received.
The power supply position can be confirmed by illumination of the indicators in the upper surroundings of
the push-button ignition switch.
PUSH-BUTTON IGNITION SWITCH OPERATING PROCEDURE
The power supply position switching operation can be performed by the following operation.
NOTE:
When an Intelligent Key is within the detection area of inside antenna and when it is inserted to the key
slot, it is equivalent to the operations below.
When starting the engine, the Intelligent Key unit monitors the engine start conditions (brake pedal operat-
ing condition, A/T selector lever position, and vehicle speed).
Unless each start condition is fulfilled, the engine will not response regardless of how many times the
push-button ignition switch is pushed. At that time, illumination repeats the position in the order of LOCK
ACC ON LOCK.

*1: When the A/T selector lever position is N position, the engine start condition is different according to the vehicle speed.
At vehicle speed of 5 km/h or less, the engine can start only when the brake pedal is depressed.
At vehicle speed of 5 km/h or more, the engine can start even if the brake pedal is not depressed. (It is the same as “Engine stall
return operation while driving”.)
*2: When the A/T selector lever position is any position other than P position and when the vehicle speed is 5 km/h or more, the engine
stop condition is different.
Press and hold the push-button ignition switch for 2 seconds or more. (When the push-button ignition switch is pressed for too short
a time, the operation may be invalid, so properly press and hold to prevent the incorrect operation.)
Press the push-button ignition switch 3 times within 1.5 seconds. (Emergency stop operation) Power supply positionEngine start/stop condition Push-button ignition
