DISASSEMBLY SERVICE POINTS

When disassembling the disc brakes, disassemble
both sides (left and right) as a set.
<<A>> PISTON BOOT/PISTON REMOVAL

CAUTION

Blow air little by little to remove the piston. The
piston will rush out if a force of air is applied
suddenly.

Place a piece of wood, etc. against the caliper body
as shown. Blow compressed air through the brake
hose to remove the piston boot and piston.

<<B>> PISTON SEAL REMOVAL

CAUTION

Do not use a flat-tipped screwdriver or similar
tool to remove piston seal. These may damage
the inner side of the cylinder.

1. Remove the piston seal with your finger tip.
2. Clean the piston surface and inner cylinder with

alcohol or brake fluid DOT 3 or DOT 4.

FEATURES

The 4ABS ensures directional stability and
controllability during hard braking.
This ABS uses a 4-sensor 3-channel system that
controls the right and left front wheels independently
of each other and controls the rear wheels
simultaneously (select low control

*

). The basic

system is the same as that of former
COLT/LANCER. 4WD models are equipped with
G-sensor.
NOTE:

*

Select low control: Control system that

compares the speeds of the right and left wheels and
performs the same fluid pressure control on both
wheels according to the speed of the wheel that is
likely to be locked.
The system has the following features:

EBD (Electronic Brake-force Distribution system)
control has been added to provide the ideal
braking force for the rear wheels.

Fail-safe function which ensures that safety is
maintained

Diagnostic function which provides improved
serviceability

EBD CONTROL

In ABS, electronic control is used so the rear wheel
brake hydraulic pressure during braking is regulated
by rear wheel control solenoid valves in accordance
with the vehicle's rate of deceleration, and the front
and rear wheel slippage which are calculated from
the signals received from the various ABS sensors.
EBD control is a control system which provides a
high level of control for both vehicle braking force
and vehicle stability. The system has the following
features:

Because the system provides the optimum rear
wheel braking force regardless of vehicle load
conditions and the condition of the road surface,
the system reduces the required pedal
depression force, particularly when the vehicle is
heavily loaded or driven on road surfaces with
high frictional coefficients.

Because the duty placed on the front brakes is
reduced, the increases in pad temperature can
be controlled during front brakes application to
improve the wear resistance characteristics of the
pad.

Control valves such as the proportioning valve
are no required.
