Installing the disc brake assembly (front brake)
To measure the rotating resistance force after installing the brake pads, first measure the rotating resistance of the wheel hub bearing with the brake pads removed.
Remove the wheel drive shaft.
Install the special tool onto the front wheel hub assembly as shown in the figure and tighten it to the specified torque.
Tightening torque: 196–255 Nm.
Use a spring dynamometer to measure the wheel bearing rotation resistance with the brake pads removed (in the forward direction).
Rear brake
Use a spring dynamometer to measure the wheel bearing rotation resistance with the brake pads removed (in the forward direction).
After installing the caliper onto the steering knuckle, install the pad guides and pads onto the caliper bracket.
Caution: Do not allow the brake disc or friction surfaces of the pads to become contaminated with oil, grease or other foreign materials.
Clean the piston and insert it into the cylinder using a special tool.
Be careful not to bind the piston boot when lowering the caliper assembly, and tighten the guide pin to the specified torque.
Tightening torque: 74 Nm.
Start the engine and then press the brake pedal 2-3 times.
Stop the engine.
Rotate the brake disc forward 10 times.
Use a spring dynamometer to measure the rotating resistance force after installing the brake pads (in the forward direction).
Calculate the increase in the resistance force to rotation.
Nominal value: 69 N or less.
If the increase in the resistance force to rotation exceeds the nominal value, disassemble the piston and clean it. Check for corrosion or wear of the piston cup, and check the smooth movement of the upper and lower guide pins.
