Bolts (M8 x 1.25)

If the rear brake disc is seized, install M8 

× 1.25 mm 

bolts as shown, and remove the disc by tightening 
the both bolts evenly and gradually.

INSTALLATION SERVICE POINT
>>A<< REAR BRAKE CALIPER ASSEM-
BLY INSTALLATION

Measure the brake drag force in the following proce-
dure.

AC402633

1. Using a spring balance, measure the hub sliding 

torque in the forward direction.

CAUTION

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

AC402607AB

MB990652

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

cylinder using the special tool, disc brake piston 
driver (MB990652).

3. Install the caliper support to the backing plate 

assembly, and assemble the pad clip and pad to 
the caliper support.

AC403232AB

Stopper groove

Protrusion

4. Set as shown so that the protrusion on the pad 

assembly rear face is engaged in the piston 
stopper groove.

5. Lower the caliper assembly while taking care not 

to catch the piston boot, and tighten the bolt to the 
specified torque.

Tightening torque: 27 

± 4 N⋅m

6. Start the engine, and depress the brake pedal 

forcibly two or three times. Then stop the engine.

7. Rotate the brake disc 10 turns in the forward 

direction.

AC402632

8. Using a spring balance, measure the hub sliding 

torque in the forward direction.

9. Obtain the disc brake drag force (difference 

between measured values of item 1 and item 7).

Standard value: 46 N or less.

10.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.
