DIAGNOSI
S 
STEP 1. Check the brake disc and pads for wear or cutting. 
Q: Is there a wear or cutting?  
YES: Repair or replace the part. Then go to Step 4 .  
NO: Go to Step 2.  
STEP 2. Check the calipers for rust. 
Q: Is there a rust?  
YES: Remove the rust. Then go to Step 4 .  
NO: Go to Step 3.  
STEP 3. Adjust the brake pedal or brake booster pushrod. 
Refer to ON
-VEHICLE SERVICE
 or MASTER CYLINDER ASSEMBLY 
AND BRAKE BOOSTER
 . 
Q: Are the brake pedal and the brake booster pushrod adjusted correctly?
YES: Go to Step 4.  
NO: Adjust the brake pedal or the brake booster pushrod. Then go to Step 
4.  
STEP 4. 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 
SYMPTOM CHART .  
INSPECTION PROCEDURE 7: SQUEALING NOISE WHEN BRAKES ARE NOT APPLIED DIAGNOSIS 
STEP 1. Check whether the backing plate is bent or loose and interfering 
with the drum

Q: Is there a fault?  
YES: Replace the part. Then go to Step 10 .  
NO: Go to Step 2.  
STEP 2. Check whether the drum is damaged due to interference with the 
backing plate or shoe. 
Q: Is there a damage?  
YES: Replace the part. Then go to Step 10 .  
NO: Go to Step 3.  
STEP 3. Check the brake drum for wear and the shoe spring for damage. 
Q: Is there a wear or damage?  
YES: Replace the part. Then go to Step 10 .  
NO: Go to Step 4.  
STEP 4. Check the brake discs for rust. 
Q: Are the brake discs rusted?  
YES: Remove the rust by using sand paper. If still rusted, turn the rotors 
with an on-the-car brake lathe. Then go to Step 10 .  
NO: Go to Step 5.  
STEP 5. Check the brake pads for correct installation. 
Q: Are the pads installed incorrectly?  
YES: Repair the pads. Then go to Step 10 .  
NO: Go to Step 6.  
STEP 6. Check the calipers for correct installation. 
Q: Are the calipers installed incorrectly?  
YES: Re
pair the cali
pers. Then 
go to Ste
p 10 .

The brake fluid level sensor is in good condition if there is no continuity when the 
float surface is above "MIN" and if there is continuity when the float surface is 
below "MIN".

DISC BRAKE PAD CHECK AND REPLACEMENT NOTE: The brake pads (LH wheel) have indicators that contact the 
brake disc when the brake pad thickness becomes 2 mm 
(0.08 inch), and emit a squealing sound to warn the driver.

1. Check the brake pad thickness through the caliper body check port. 
Standard value: 10.0 mm (0.39 inch)  
Minimum limit: 2.0 mm (0.08 inch)

CAUTION:
Whenever a pad must be replaced, replace both 
LH and RH wheel pads as a set to prevent the 
vehicle from pulling to one side when braking.  If there is a significant difference in the 
thicknesses of the pads on the left and right 
sides, check the sliding condition of the piston 
and slide pins.

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
).

INSTALLATION SERVICE POINT >>A<< BRAKE CALIPER ASSEMBLY INSTALLATION 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

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.

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: 68 N (15 pounds) or less
