DRIVE SHAFT
DESCRIPTION
The 5S±FE engine model continues to use the same drive shaft used on the previous model.
Previously, the inboard joint of the drive shaft on the 1MZ±FE engine model was the bolt±mounted type. However,
on the new model, the inboard joint is the friction±welded integrated type.
On the new model with 1MZ±FE engine, the boot of the outboard joint are made of thermoplastic elastomer, which
has superior durability.

BRAKES
DESCRIPTION
The ventilated disc brake is used for front brake on all models.
The rear drum brake is used on the 5S±FE engine model, and the rear solid disc brake is used on the 1MZ±FE engine
model.
The ABS is provided on the 5S±FE engine CE grade model as an option and on other models as standard.
An ABS actuator has been changed to the 2±position solenoid valve type actuator.
A compact and lightweight ABS & TRAC system, in which the ABS and TRAC functions are integrated, is made
available as an option on the LE and XLE grade models with the 1MZ±FE engine.
A portless and portless type master cylinder is used on the models with ABS & TRAC system.
The center lever type parking brake is adopted on all models.

MASTER CYLINDER
As in the previous model, the lockheed and
lockheed type master cylinder is used on the models
without ABS, and the portless and lockheed type
master cylinder is used on the models with ABS.
The portless and portless type master cylinder is
used on the models with ABS & TRAC system.
ABS
1. General
As in the previous model, the braking of each wheel is controlled by the following 3 modes: pressure reduction,
pressure holding, and pressure holding mode.
During ABS activation, the ECU controls the fluid pressure of each front left and right wheels independently while
the fluid pressure of rear left and right wheels is controlled simultaneously.
However, the ABS actuator has been changed as shown in the table below. In addition, the diagnostic codes have
alsom been changed.
For diagnostic code check method, diagnostic code and diagnostic code clearance, see the 1997 Camry Repair
Manual (Pub. No. RM503U).
The operation of the ABS is the same as that of the '96 Corolla.
