DISASSEMBLY SERVICE POINTS
Caution: Brembo disc brake
Take care not to contact the parts or tools to the caliper
because the paint of caliper will be scratched. And if
there is brake fluid on the caliper, wipe out quickly.
AA"PISTON BOOT/PISTON REMOVAL

Remove the piston boot by pumping in air slowly from the
brake hose connection. Be sure to use the handle of a plastic
hammer and adjust the height of the two pistons while so
that the pistons protrude evenly.
Caution
Do not remove one piston completely before trying to
remove the other piston, because it will become
impossible to remove the second piston.

Use a piece of wood to protect the caliper body outer side,
and then apply compressed air through the brake hose
connection hole to withdraw the piston and piston boot.
Caution
If air is blown into the caliper body suddenly, the piston
will pop out, causing damage to the caliper body. Be
sure to apply compressed air gradually.
AB"PISTON SEAL REMOVAL
1. Remove the piston seal with finger tip.
Caution
Do not use a flat-tipped screwdriver or other tool to
prevent damage to inner cylinder.
2. Clean piston surface and inner bore with trichloroethylene,
alcohol or the specified brake fluid.
Specified brake fluid: DOT3 or DOT4

"AALOCK PIN/GUIDE PIN INSTALLATION

As shown in the illustration, align the identification mark on
the caliper body and the head mark of the guide pin/lock
pin, then install the guide pin/lock pin.
INSPECTION
DCheck the cylinder for wear, damage or rust.
DCheck the piston surface for wear, damage or rust.
DCheck the caliper body or sleeve for wear.
DCheck pad for damage or adhesion of grease, check
the backing metal for damage.
PAD WEAR CHECK
Measure thickness at the thinnest and worn area of the pad.
Replace the pad assembly if the pad thickness is less than
the limit value.
Standard value:
10.0 mm ,
9.0 mm
Limit: 2.0 mm
Caution
1. Always replace the brake pads as an axle set.
2. If an excessive difference is found in the thickness
between the right and left brake pads, check moving
parts.

ABS <4WD> -General Information35B-2
GENERAL INFORMATION
ABS has been adopted as optional equipment in
RS-IIto maintain directional stability and steering
performance during sudden braking or braking on
slippery road surfaces.
The ABS control method is a 4-sensor, 4-channel
method which provides independent control for all
wheels.
Following system for Lancer EVOLUTION-VII has
been modified from Lancer EVOLUTION-VI Tommi
Makinen Edition.DBy adding lateral G sensor, longitudinal G
sensor and steering wheel sensor, optimized
ABS control at the time of cornering.
DBy inputting parking brake switch signal to
ABS-ECU with pulling parking brake lever, ABS
control has been optimized.
DABS-ECU outputs ABS signal to 4WD-ECU.
DG sensor (lateral), steering wheel sensor and
parking brake switch have been added to the
diagnosis and service data.
DABS-ECU connector has been changed.
EBD CONTROL
In ABS, electronic control method is used by which
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 each wheel speed
sensor’s signal. 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:
DBecause the system provides the optimum rear
wheel braking force regardless of the vehicleladen condition and the condition of the road
surface, the system reduces the required pedal
depression force, particularly when the vehicle
is heavily laden or driving on road surfaces
with high frictional coefficients.
DBecause the duty placed on the front brakes
has been reduced, the increases in pad
temperature can be controlled to improve the
wear resistance characteristics of the pad,
during front brakes applying.
DControl valves such as the proportioning valve
are no longer required.
