SYMPTOM PROCEDURES INSPECTION PROCEDURE 1: VEHICLE PULLS TO ONE SIDE WHEN BRAKES ARE APPLIED DIAGNOSIS
STEP 1. Check for oil, water, etc., on the pad contact surface of all brakes.
Q: Is oil, water, etc., on the pad contact surface?
YES: Replace the part and determine the source/cause of foreign material.
Then go to Step 5 .
NO: Go to Step 2.
STEP 2. Check disc brake pistons for smooth operation.
1. With engine not running, depress the brake pedal rapidly several times to
deplete booster vacuum reserves.
2. Test each disc brake assembly one at a time.
a. Remove the lower caliper bolt, then remove caliper from mount.
b. Have an assistant slowly depress the brake pedal. Confirm piston(s)
extend slowl
y and smoothl
y with no
jum
piness. Re

to Step 7 .
NO: Go to Step 5.
STEP 5. Check for oil, water, etc., on the pad contact surfaces of all
brakes.
Q: Is oil, water, etc., on the pad contact surface?
YES: Replace the part and determine the source/cause of foreign material.
Recheck symptom. Then go to Step 7 .
NO: The procedure is complete. If condition persists for vehicles without
ABS, go to Step 6.
STEP 6. Check the proportioning valve operation. < Vehicles without
ABS>
Refer to PROPORTIONING VALVE FUNCTION TEST < Vehicles
without ABS>
.
Q: Is there a fault?
YES: Replace the proportioning valve. Then go to Step 7.
NO: Go to Step 7.
STEP 7. Recheck symptom.
Q: Is the symptom eliminated?
YES: The procedure is complete.
NO: Start over at Step 1 . If a new symptom surfaces, refer to the
appropriate SYMPTOM CHART
.
INSPECTION PROCEDURE 3: INCREASED PEDAL STROKE (REDUCED PEDAL-TO-FLOOR BOARD
CLEARANCE) DIAGNOSIS
STEP 1. Check for spongy (not firm) brakes.
1. With engine not running, depress the brake pedal rapidly several times to
de
plete booster vacuum reserve.

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.

3. Turn the ignition switch to the ON position and select BELT TENSION
MEASUREMENT from the menu screen on Scan Tool (MB991958).
4. Hold Microphone (part of Belt Drive Meter Set) (MB991668) near the center
of the drive belt between the pulleys away from the rear surface of the belt and
perpendicular to the belt (no more then 15 degrees in either direction). See Fi
g.
3 and Fig. 4
.
5. Gently tap the middle of the belt between the pulleys with your finger, and
check that the vibration frequency of the belt is within specification. See Fig. 3
and Fig. 4
. See DRIVE BELT ADJUSTMENT SPECIFICATIONS
table.
CAUTION: Temperature of the surface of the belt should be
as close possible to underhood temperature.
CAUTION: DO NOT let contaminants such as water or oil get
onto the microphone. If strong gusts of wind
blow against the microphone or if there are any
loud sources of noise nearby, the values
measured by the microphone may not
correspond to actual values. DO NOT take
measurement while engine is running.

DIAGNOSI
S
STEP 1. Remove the radiator cap and check for coolant contamination.
Q: Is the coolant contaminated with rust and oil?
YES: Replace it. Refer to ENGINE COOLANT REPLACEMENT
.
NO: There is no action to be taken. Go to Step 2.
STEP 2. Check the radiator cap valve opening pressure.
1. Use a cap adapter to attach the cap to the tester.
2. Increase the pressure until the gauge indicator stops moving.
Minimum limit: 83 kPa (12 psi)
Standard value: 93 - 123 kPa (14 - 18 psi)
NOTE: Be sure that the cap is clean before testing. Rust or
other foreign material on the cap seal will cause an
improper reading.

ROTOR 1. Check the continuity between the slip rings of the field coil. If the resistance
value is not within 2-5ohm, replace the rotor. See Fig. 11
.
2. Check the continuity between the slip ring and the core. If there is continuity,
re
place the rotor. See Fig. 12
.

RECTIFIER 1. Check the continuity between the positive rectifier and the stator coil lead
connection terminal with a tester. If there is continuity between the terminals,
the diode is shorted, so replace the rectifier. See Fig. 13
.
2. Check the continuity between the negative rectifier and the stator coil lead
connection terminal with a tester. If there is continuity between the terminals,
the diode is grounded, so replace the rectifier. See Fig. 14 .
3. Check the continuity of the 3 diodes by connecting an ohmmeter to both ends
of each diode. If there is continuity between the directions, or if there is no
continuit
y, the diode is dama
ged, so re
place the rectifier. See Fi
