DISASSEMBLY SERVICE POINTS

CAUTION

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 cali-
per, wipe it off quickly.
When disassembling the disc brakes, disassemble
both sides (left and right) as a set.

<<A>> PISTON BOOT/PISTON REMOVAL

AC212149

AB

Wooden plate

Remove the pistons by pumping in air slowly from
the brake hose connection. Be sure to use a wood
plate and adjust the height of the two pistons while
so that the pistons protrude evenly.

<<B>> PISTON SEAL REMOVAL

CAUTION

To prevent damage to inner cylinder, do not use a
flat-tipped screwdriver or other tool.
1. Remove the piston seal with finger tip.
2. Clean the piston surface and inner cylinder with

alcohol or brake fluid DOT 3 or DOT 4.

INSPECTION

M1351007300296

• Check the cylinder for wear, damage or rust.

• Check the piston surface for wear, damage or

rust.

• Check the caliper body for wear.

• Check the pad for damage or adhesion of grease,

check the backing metal for damage.

PAD WEAR CHECK

WARNING

•

Always replace both brake pads on each
wheel as a set (both front wheels or both
rear wheels). Failure to do so will result in
uneven braking, which may cause unrelia-
ble brake operation.

•

ACX00690

If there is significant difference in the
thickness of the pads on the left and right
sides, check the moving parts.

Measure thickness at the thinnest, most worn area of
the pad. Replace the pad assembly if pad thickness
is less than the limit value.

Standard value: 9.0 mm
Minimum limit: 2.0 mm

WARNINGS REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES

WARNING

•

Improper service or maintenance of any component of the SRS, or any SRS-related component, can lead to

personal injury or death to service personnel (from inadvertent firing of the air bag) or to the driver and passenger

(from rendering the SRS inoperative).

•

Service or maintenance of any SRS component or SRS-related component must be performed only at an

authorized MITSUBISHI dealer.

•

MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B - Supplemental

Restraint System (SRS) before beginning any service or maintenance of any component of the SRS or any

SRS-related component.

NOTE

The SRS includes the following components: SRS-ECU, SRS warning lamp, air bag module, clock spring, and interconnecting

wiring. Other SRS-related components (that may have to be removed/installed in connection with SRS service or maintenance)

are indicated in the table of contents by an asterisk (*).

ANTI-SKID BRAKING SYSTEM (ABS)

GENERAL INFORMATION

M1352000100584

Top components such as Brembo

™ brakes, EBD and

sports ABS improve braking power and braking sta-
bility.

SPORTS ABS

• 4-wheel independent control optimises the brake

force to each wheel to achieve a balance of
improved braking force and braking stability.

• A steering wheel sensor was added to monitor

the steering angle status. Braking force is altered
in response to the steering status to improve the
quality of steering when cornering.

• The steering wheel sensor, lateral G-sensor and

longitudinal G-sensor accurately monitor driving
conditions and optimise ABS control to match the
specific driving conditions.

EBD (ELECTRONIC BRAKE-FORCE DISTRIBUTION SYSTEM)

• Rear brake power is electronically controlled to

optimise performance in accordance with road
and load conditions and to ensure optimal distri-
bution of braking force between the front and rear
brakes.

• Rear brake fluid pressure control employs a

brake modulator hydraulic unit solenoid valve that
made it possible to eliminate the pressure control
valves (proportioning valves).

• Effective use of rear wheel brake force reduces

temperature build-up in the front brakes under
hard braking conditions.

• Independent control of the left and right rear

brakes when braking during cornering achieves a
balance of improved vehicle stability and braking
force.
