INSTALLATION

1. In order to measure the brake drag force after pad

installation, measure the hub sliding torque in the
forward direction (with no pad attached) using a
spring balance.

CAUTION

Keep grease or other fouling off the pad and
brake disc friction surface.

2. Clean the piston, and press the piston into the

cylinder using the special tool, piston expander
(MB990520).

3. Assemble the pad clip and pad to the caliper

support, and tighten the slide pin bolt to the
specified torque.

Tightening torque: 49

± 4 N⋅m

4. Start the engine, and depress the brake pedal

forcibly two or three times. Then stop the engine.

5. Rotate the brake disc 10 turns in the forward

direction.

AC210114AB

6. Using a spring balance, 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: 83 N 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.
