3. Remove the following parts from the caliper support.
(1) Pad assembly
(2) Clip
4. In order to measure the brake drag force after pad
installation, measure the rotary-sliding resistance of the hub
with the pads removed (Refer to P.35A-30).
5. Install the pads and caliper assembly, and then check the
brake drag force (Refer to P.35A-30).
6. Tighten lock pin bolt. Ensure lock pin is held with spanner
while tightening lock pin bolt(Rear) to specified torque.
DISC BRAKE ROTOR CHECKM1351002900334
Disc brakes must be kept within the allowable
service values in order to maintain normal brake
operation.
Before turning the brake disc, the following condi-
tions should be checked.

.
BRAKE DISC THICKNESS CHECK
1. Using a micrometer, measure disc thickness at eight
positions, approximately 45 degrees apart and 10 mm (0.4
inch) in from the outer edge of the disc.
FRONT BRAKE DISC
Standard value: 26.0 mm (1.02 inches)
Minimum limit: 24.4 mm (0.96 inch)
REAR BRAKE DISC
Standard value: 10.0 mm (0.39 inch)
Minimum limit: 8.4 mm (0.33 inch)
NOTE: Thickness variation (at least 8 positions) should not
be more than 0.015 mm (0.0006 inch). INSPECTION ITEM REMARK
Scratches, rust, saturated lining materials and wear
If the vehicle is not driven for a long period of
time, sections of the discs that are not in contact
with the pads will become rusty, causing noise
and shuddering.
If grooves and scratches resulting from excessive
disc wear are not removed prior to installing a new
pad assembly, there will be inadequate contact
between the disc and the lining (pad) until the
pads conform to the disc.
Run-out Excessive run-out of the discs will increase the pedal
depression resistance due to piston kick-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 warping or distortion.

>>A<< BRAKE DRAG FORCE CHECK
1. In order to measure the brake drag force, measure the hub
torque with the pads removed by the following procedure.
Use a spring scale to measure the hub torque in the forward
direction. Record hub torque with pads removed.
Do not let any oil, grease or other contamination get onto
the friction surfaces of the pads and brake discs.
2. After re-installing the caliper support to the knuckle, install
the pad clips and the pads to the caliper support.
3. Clean the piston and insert into cylinder with special tool
MB990520.
4. Be careful that the piston boot does not become caught,
when lowering the caliper assembly and installing the lock
pin bolt.
5. Check the brake drag force as follows.
(1) Start the engine and hold the brake pedal down for 5
seconds. [Pedal depression force: approximately 200 N
(45 pound)]
(2) Stop the engine.
(3) Turn the brake disc forward 10 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:
3.8L engine> 64 N (14 pounds) or less
54 N (12 pounds) or less
6. If the brake drag force 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.
