2. Remove the lock pin bolt. Pivot the caliper assembly and hold it with wires.
CAUTION: Do not wipe off the special grease that is on the
lock pin or allow it to contaminate the lock pin.

3. Remove the following parts from caliper support.
1. Pad assembly
2. Pad and wear indicator assembly or Pad assembly
3. Shim
4. 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
INSPECTION
).
5. Install the pads and caliper assembly, and then check the brake drag force
(Refer to INSPECTION
).

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.
CAUTION: Do not let any oil, grease or other contamination
get onto the friction surfaces of the pads and
brake discs.

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.

Attach a guide pin (with "g" on the bolt head) at the bleeder nipple side of the
caliper body and a lock pin (with "l" on the bolt head) at the opposite side. INSPECTION
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 1. Measure thickness at the thinnest and most worn area of the pad.
Standard value: 10 mm (0.39 inch)
Minimum limit: 2.0 mm (0.08 inch)
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 and slide pins.

TEST B: RADIATOR FAN & CONDENSER FAN DO NOT CHANGE SPEED OR STOP Technical Description The fan control module has variable control of the radiator fan motor and the
condenser fan motor speeds using signals transmitted from the PCM. Troubleshooting Hints
Malfunction of fan control relay. Malfunction of fan control module. Malfunction of PCM.
Diagnosis 1. Check the fan control relay. See FAN CONTROL RELAY
under
COMPONENT TESTS. If fan control relay is okay, go to next step. If fan
control module is damaged, repair or replace as necessary and retest.
2. Check the harness wire between terminal No. 2 of fan control relay connector
A-10X and terminal No. 3 of fan control module connector A-18. See Fig. 7
and Fig. 8
. If wiring is damaged, repair or replace as necessary and retest. If
wiring is okay, go to next step.
3. Disconnect all the connectors from the PCM. Connect Power Plant ECU Check
Harness (MB991923
) between the PCM and the bod
y-side harness connector.
NOTE: If the engine coolant temperature reaches 230°F (110°C) or
higher, the radiator fan control runs the radiator fan for up
to 5 minutes even after the ignition switch is turned to the
LOCK position. The fan stops its rotation when the engine
coolant temperature decreases to 230°F (110°C) or l ower.
NOTE: Measure the output circuit voltage at terminal No. 10 of
PCM connector B-18 by using Power Plant ECU Check
Harness (MB991923). See Fig. 11
and Fig. 12
.

1. Ensure that the ignition switch is at the "LOCK" (OFF) position.
2. Start up the personal computer.
3. Connect special tool MB991827 to special tool MB991824 and the personal
com
puter.
CAUTION: To prevent damage to scan tool MB991958, always
turn the ignition switch to the "LOCK" (OFF) position
before connecting or disconnecting scan tool
MB991958.
