<<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.

ASSEMBLY SERVICE POINTS

>>A<< LOCK PIN/GUIDE PIN INSTALLATION <2.4L
ENGINE>
Install the guide pin as illustrated that each head mark of the
guide pin and the lock pin matches the indication mark ("G" or
"L") located on the caliper body.

>>B<< BUSHING/LOCK PIN/GUIDE PIN INSTALLATION
<3.0L ENGINE>
Install the bushing and lock pin to the bleeder nipple side at the
caliper body, the guide pin to its opposite side, respectively.

INSPECTION

M1351006300099

•

Check the cylinder for wear, damage or rust.

•

Check the piston surface for wear, damage or rust.

•

Check the caliper body or sleeve 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 unreliable brake operation.

•

If there is significant difference in the thickness of
the pads on the left and right sides, check the
sliding condition of the piston, lock pin and guide
pin.

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

Standard value: 10 mm (0.39 inch)
Minimum limit: 2.0 mm (0.08 inch)

INSTALLATION SERVICE POINT

>>A<< REAR BRAKE ASSEMBLY INSTALLATION
1. In order to measure brake drag torque after pad installation,

measure hub torque with the pads removed.

2. Use a spring scale to measure hub torque in the direction

shown. Record the value.

CAUTION

Do not let any oil, grease or other contamination get onto
the friction surfaces of the pads and brake discs.
3. After re-installing the caliper support, install the pad clips

and pads to the caliper support.

4. Clean the piston and insert it into the cylinder with special

tool MB990520.

5. Be careful that the piston boot does not become caught,

when lowering the caliper assembly and installing the guide
pin.

6. Check brake drag force as follows:

(1) Start the engine and hold the brake pedal down for five

seconds. [Pedal depression force: approximately 196 N
(44 pound)]

(2) Stop the engine.
(3) Turn the brake disc forward ten times.
(4) Use a spring scale to measure the hub torque with pads

installed in the same direction as earlier.

(5) Calculate the drag force of the disc brake [difference

between hub torque with pads installed and hub torque
with pads removed].

Standard value: 69 N (16 pound) or less

7. If the drag torque exceeds the standard value, disassemble

and clean the piston. Check for corrosion or worn piston
seal, and check the sliding condition of the lock pin and
guide pin.
