GENERAL
BASIC BRAKE SYSTEM35A-2
GENERALM2350000100956
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.

CONSTRUCTION DESCRIPTION
BASIC BRAKE SYSTEM35A-6
VARIABLE BOOST RATIO MECHANISM
The variable boost ratio mechanism changes the input/output
characteristics of the brake booster in two phases by changing
the reaction force applied to the valve plunger during the assist
phase.
.
AT INITIAL ASSISTING
1. When the brake pedal is not depressed (no input load
applied), the reaction washer is not deformed.
2. When the brake pedal is depressed, the reaction washer is
deformed to reach the ring piston and disc, then the first
input characteristics begin (Ratio 1).
.
AT AN INCREMENT OF ASSIST RATIO
1. The reaction washer is further deformed and pushes down
the ring piston and lock washer, deflecting the spring. All the
force pushing the ring piston and disc is transferred to the
brake pedal via spring seat and disc as the reaction force.
2. The reaction washer is then further deformed, and when the
lock washer makes contact with the control housing, the
input characteristics change. All the force applied from the
reaction washer to the ring piston is now transferred to the
control housing via the lock washer, so no force is applied to
the brake pedal. The second input characteristics (Ratio 2)
begin.

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.
