INSTALLATION SERVICE POINT



>>A<< REAR BRAKE CALIPER ASSEMBLY INSTALLATION


Measure the brake drag force in the following procedure:

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

2.
caution Keep grease or other soiling off the pad and brake disc friction surfaces.
Clean the piston, and press the piston into the cylinder using special tool piston expander (MB990520).
3.Install the caliper support to the backing plate assembly, and assemble the pad clip and pad to the caliper support.
4.Lower the caliper assembly with care not to catch the piston boot, and tighten the lock pin to the specified torque.
Tightening torque: 44 ± 5 N·m
5.Start the engine, and depress the brake pedal forcibly two or three times. Then, stop the engine.
6.Turn the brake disc 10 times in the forward direction.

7.Using a spring balance, measure the hub sliding torque in the forward direction.
8.Obtain the disc brake drag force (difference between measured values of item 1 and item 7).
Standard value: 68 N or less
9.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.
