>> B << Brake Caliper Assembly Installation

WARNING: This page is about a different car, the 2008 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.

Measure the brake drag force in the following procedure:

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.

Clean the piston, and press the piston into the cylinder using the piston expander (Special tool: MB990520).
Assemble the pad clip and pad to the caliper support, and tighten the guide pin to the specified torque.
Tightening torque: 44 ± 5 N.m (32 ± 4 ft-lb)
Start the engine, and depress the brake pedal forcibly two or three times. Then, stop the engine.
Turn the brake disc 10 times in the forward direction.

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