INSTALLATION SERVICE POINT

.

>>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.

CAUTION

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:
<Front

3.8L engine> 64 N (14 pounds) or less

<Rear> 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.
