GENERAL INFORMATION
FRONT AXLE26-2
GENERAL INFORMATIONM2260000100819
For the front axle, a double-row angular contact ball
bearing with an integral oil seal is adopted as a
wheel bearing, and EBJ-ETJ type constant velocity
joint as a driveshaft.
It has the following features:
•The driveshaft incorporates lightweight and com-
pact EBJ-ETJ type constant velocity joints.
•Lead-free grease for the constant velocity joint is
adopted.
•Hexavalent chromium is eliminated from the dust
cover material.
•The number of parts is reduced by integrating the
magnetic encoder for ABS wheel speed detection
into the wheel bearing.
NOTE: .
ETJ (High Efficiency Compact Tripod Joint): the
lighter and smaller constant velocity joint com
-
pared with the conventional TJ has been
installed.
EBJ (High Efficiency Compact Birfield Joint): the
lighter and smaller constant velocity joint com
-
pared with the conventional BJ has been
achieved by adopting the eight small balls.

Brake systems with higher reliability and durability
have achieved distinguished braking performance.
FEATURES
.
IMPROVEMENT OF BRAKING PERFOR-
MANCE
•A 10-inch single brake booster with the variable
boost ratio mechanism has been used to assure
maximum braking force with less pedal pressure
in case of emergency.
•In addition to the 10-inch single brake booster, a
small and long stroke-type master cylinder has
been adopted to achieve downsizing and secure
assist force.
•15-inch or 16-inch ventilated disc brakes have
been adopted for the front.
•8-inch leading trailing-type drum brake, 14-inch
or 16-inch solid disc brake has been adopted for
the rear.
.
IMPROVEMENT IN SAFETY
•The 4-wheel anti-lock brake system (4ABS) has
been installed to prevent slippage resulting from
the wheel lock and assure stable vehicle posture
and driveability.
•A rear wheel early lock-prevention proportioning
valve has been used.
•Electronic control braking force distribution sys-
tem (EBD) has been adopted to assure the maxi-
mum braking force independently of the
passenger's position in the vehicle. with ABS>
•X-type piping of brake lines have been adopted
for the front and rear wheels.
•Audible wear indicators are used on the front and
rear brake pads to warn the driver of wear limit.
.
SERVICE QUALITY IMPROVEMENTS
•Diagnostic function has been adopted to ABS for
easier inspection.
•Brake fluid reservoir, master cylinder, and brake
booster have been integrated for downsizing and
better serviceability.

GENERAL INFORMATION
FOUR-WHEEL ANTI-LOCK BRAKE SYSTEM (4ABS)35B-2
GENERAL INFORMATIONM2351000100830
The ABS that ensures directional stability and con-
trollability during hard braking. ABS is standard
equippment on the ES and GTS models but is
optional.
This ABS uses a 4-sensor system that controls all
four wheels independently of each other, and has the
following features:
•EBD *1 (Electronic Brake-force Distribution sys-
tem) control that can obtain ideal rear wheel
brake force has been employed.
•The magnetic encoder for detecting the wheel
speed has been installed instead of the rotor as
the wheel speed sensor.
•For wiring harness saving and secure data com-
munication, CAN *2 bus has been adopted as a
tool of communication with other ECUs.
NOTE: .
•*1: EBD (Electronic Brake-force Distribution)
•*2: For more information about CAN (Controller
Area Network), refer to GROUP 54C
P.54C-2.
