REMOVAL AND INSTALLATION
Caution
1. If the vehicle is equipped with the Brembo disc brake, during maintenance, 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.
2. For vehicles with ABS or ACD, do not strike the rotor for wheel speed sensor installed to
the B.J. outer race of drive shaft against other parts when removing or installing the drive
shaft. Otherwise the rotor for wheel speed sensor will be damaged.

(5) Apply repair kit grease to the portions of the pads
indicated on the left. At this time, make sure that
the grease will not be applied to any other surfaces.
(6) Mount the pads to the caliper so that its side with
the wear indicator is on the outside of the vehicle.
With the rear pads, ensure that the arrow on the
pad faces in the same direction as the brake disc
turns when the vehicle moves forward.
(7) Holding the cross spring with one hand, fit pins in
the caliper.
(8) Using a spring balance, measure the turning sliding
resistance of the hub in the forward direction.
(9) Find the brake disc drag force [the difference in
measurements taken in step(3) and in step(8)].
Standard value: 69 N or less
DISC BRAKE ROTOR CHECK
Caution
When servicing disc brakes, it is necessary to exercise caution to keep the disc brakes within
the allowable service values in order to maintain normal brake operation.
Before re-finishing or re-processing the brake disc surface, the following conditions should be checked.
Inspection itemsRemarks
Scratches, rust, saturated lining materials
and wearDIf the vehicle is not driven for a certain period, the sections of
the discs that are not in contact with lining will become rusty, causing
noise and shuddering.
DIf grooves resulting from excessive disc wear and scratches are
not removed prior to installing a new pad assembly, there will
momentarily be inappropriate contact between the disc and the
lining (pad).
Run-out or driftExcessive run-out or drift of the discs will increase the pedal depression
resistance due to piston knock-back.
Change in thickness (parallelism)If the thickness of the disc changes, this will cause pedal pulsation,
shuddering and surging.
Inset or warping (flatness)Overheating and improper handling while servicing will cause inset or
warping.

BRAKE DISC THICKNESS CHECK
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.
1. Using a micrometer, measure disc thickness at eight
positions, approximately 45°apart and 10 mm in from
the outer edge of the disc.
Brake disc thickness
Standard value: 24.0 mm , 20.0 mm
Limit: 22.4 mm , 18.4 mm
Brake disc thickness
Standard value:32.0 mm , 22.0 mm
Limit: 29.8 mm , 20.4 mm
Thickness variation (at least 8 positions)
The difference between any thickness measurements
should not be more than 0.015 mm.
2. If the disc is beyond the limits for thickness, remove it
and install a new one. If thickness variation exceeds the
specification, replace the brake disc or grind it with
on-the-car type brake lathe (“MAD, DL-8700PF” or
equivalent).
Caution
(1) After a new brake disc is installed, always grind
the brake disc with on-the-car type brake lathe.If
this step is not carried out, the brake disc run-out
exceeds the specified value, resulting in judder.
(2) When the on-the-car type lathe is used, first install
M12 flat washer on the stud bolt in the brake disc
side according to the figure, and then install the
adapter. If the adapter is installed with M12 flat
washer not seated, the brake disc rotor may be
deformed, resulting in inaccurate grinding.
(3) Grind the brake disc with all wheel nuts diagonally
and equally tightened to the specified torque 100
N·m. When all numbers of wheel nuts are not used,
or the tightening torque is excessive or not equal,
the brake disc rotor or drum may be deformed,
resulting in judder.
BRAKE DISC RUN-OUT CHECK AND
CORRECTION
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.
1. Remove the brake assembly, and then hold it with wire.
2. Temporarily install the disc with the hub nut.

3. Place a dial gauge approximately 5 mm from the outer
circumference of the brake disc, and measure the run-out
of the disc.
Limit: 0.03 mm or less
4. If the brake disc run-out exceeds the limit, correct it as
follows:
(1) Chalk phase marks on the wheel stud and the brake
disc, which run-out is excessive.
(2) Remove the brake disc. Then place a dial gauge
as shown, and measure the wheel bearing axial play
by pushing and pulling the wheel hub.
Limit: 0.06 mm , 0.05 mm
(3) If the wheel bearing axial play exceeds the limit,
disassemble the hub and knuckle assembly to check
each part.
(4) If the wheel bearing axial play does not exceed the
limit, dephase the brake disc and secure it. Then
recheck the brake disc run-out.
5. If the run-out cannot be corrected by changing the phase
of the brake disc, replace the brake disc or grind it with
the on-the-car type brake lathe ( “MAD, DL-8700PF” or
equivalent).
Caution
(1) After a new brake disc is installed, always grind
the brake disc with on-the-car type brake lathe.
If this step is not carried out, the brake disc run-out
exceeds the specified value, resulting in judder.
(2) When the on-the-car type lathe is used, first install
M12 flat washer on the stud bolt in the brake disc
side according to the figure, and then install the
adapter. If the adapter is installed with M12 flat
washer not seated, the brake disc rotor may be
deformed, resulting in inaccurate grinding.
(3) Grind the brake disc with all wheel nuts diagonally
and equally tightened to the specified torque 100
N·m. When all numbers of wheel nuts are not used,
or the tightening torque is excessive or not equal,
the brake disc rotor or drum may be deformed,
resulting in judder.

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.
