dash panel shown in the illustration.
Standard pedal reserve distance
If the distance is not as specified, troubleshoot
the brake system.
ADJUSTMENT
(2006/01- )
1. CHECK AND ADJUST BRAKE PEDAL HEIGHT
(a) Check the pedal height.
Standard pedal height from dash panel:
184.2 to 194.2 mm (7.252 to 7.646 in.)
(b) Adjust the pedal height.
(1) Disconnect the connector from the stop light
switch.
(2) Remove the switch.
(3) Loosen the push rod clevis lock nut.

REMOVAL
(2005/11-2006/01)
NOTICE:
• The master cylinder and piston are designed so that
the piston can easily fall out. Prevent this by making
sure that the tip of the master cylinder points
downward when handling the master cylinder.
• Make sure foreign matter does not attach to the
master cylinder's piston. If foreign matter attaches,
clean it off with a cloth. Then apply lithium soap base
glycol grease to the entire outer circumference
contact surface area of the piston.
1. REMOVE AIR CLEANER CASE SUB-ASSEMBLY
(a) Remove the air cleaner case (see page EM-98).
HINT:
Refer to the procedures from the removal of the
purge VSV up until the removal of the air cleaner
case.
2. DRAIN BRAKE FLUID
NOTICE:
Wash off brake fluid immediately if it comes in
contact with any painted surface.
3. REMOVE BRAKE MASTER CYLINDER SUB-
ASSEMBLY
(a) Release the vacuum pressure in the brake booster
as follows.
(1) Stop the engine.
(2) Depress the brake pedal several times.
(b) Disconnect the brake fluid level warning switch
connector labeled A.
(c) Using SST, disconnect the 2 brake lines labeled B
from the master cylinder.
SST 09023-00101
(d) Remove the 2 nuts.
(e) Pull out the master cylinder from the brake booster.
NOTICE:
• The master cylinder and piston are designed
so that the piston can easily fall out. Prevent
this by making sure that the tip of the master
cylinder points downward when handling the
master cylinder.

FREEZE FRAME DATA
1. FREEZE FRAME DATA
NOTICE:
• It is difficult to show the specified values
(judgment values) clearly because freeze frame
data values change significantly due to
differences in measurement conditions,
surroundings, or vehicle conditions. For this
reason, there may be a problem even when the
values are within specifications.
• Turn the ignition switch ON and park the vehicle
on level ground. Check the freeze frame data by
using intelligent tester.
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON and check the freeze
frame data by following the prompts on the
intelligent tester display.

FAIL-SAFE CHART
If a problem occurs in the electric power steering system, the
P/S warning light will come on in the combination meter and
steering power assist will be stopped, fixed at a particular
point, or decreased simultaneously to protect the system.
Electronic power steering system
HINT:
The amount of power assist may be decreased to prevent the
motor and ECUs from overheating if the steering wheel is
continuously turned when the vehicle is either stopped or
driven at a low speed, or if the steering wheel is kept at either
full lock position for a long time. In such cases, the amount of
power assist returns to normal if the steering wheel is not
turned for approximately 10 minutes with the engine idling.
