FRONT DISC BRAKE ASSEMBLY

REMOVAL AND INSTALLATION

Removal Steps 1-7:

INSTALLATION SERVICE POINTS

]]A[[ BRAKE HOSE INSTALLATION
1. Pass the brake hose through the hole in the body-side bracket.
2. Install the brake hose to the brake caliper.
3. Install the brake hose at the two fixing points.





4. Twist the brake hose toward the lesser torsion between the brake hose and body-side bracket as shown in the figure, and fix it to the body-side bracket with a clip.

]]B[[ BRAKE CALIPER ASSEMBLY INSTALLATION
Measure the brake drag force in the following procedure:





1. Using a spring scale, measure the hub sliding torque in the forward direction.

CAUTION
Keep grease or other soiling off the pad and brake disc friction surfaces.





2. Clean the piston, and press the piston into the cylinder using the piston expander (Special tool: MB990520).
3. Assemble the pad clip and pad to the caliper support, and tighten the guide pin to the specified torque.

Tightening torque: 44 ± 5 Nm (32 ± 4 ft-lb)

4. Start the engine, and depress the brake pedal forcibly two or three times. Then, stop the engine.
5. Turn the brake disc 10 times in the forward direction.





6. Using a spring scale, measure the hub sliding torque in the forward direction.
7. Obtain the disc brake drag force (difference between measured values of item 1 and item 6).

Standard value: 68 N (15.3 pounds) or less

8. If the brake drag force exceeds the standard value, disassemble the piston to check for fouling/rust on the piston sliding section and piston/seal deterioration, and confirm whether the slide pin slides properly.
