REMOVAL AND INSTALLATION
Installation Service Point
>A< Disc Brake Assembly Installation
1. In order to measure the brake drag force after pad installation, measure the rotary-sliding resistance of the hub by the following procedure with the pads removed.
1. Remove the drive shaft.





2. Attach the special tool to the front hub assembly as shown in the illustration, and tighten it to the specified torque.
Tightening torque: 177 - 275 Nm (130 - 203 ft. lbs.)





3. Use a spring scale to measure the rotary-sliding resistance of the hub in the forward direction.
2. After installing the caliper support to the knuckle, install the pad clips and the pads to the caliper support.

CAUTION: Do not let any oil, grease or other contamination get onto the friction surfaces of the pads and brake discs.





3. Clean piston and insert into cylinder with special tool.
4. Be careful that the piston boot does not become caught when lowering the caliper assembly, and tighten the slide pin (M14) to the specified torque.
Tightening torque: 83 - 93 Nm (61 - 69 ft. lbs.)
5. Start the engine and then depress the brake pedal 2 - 3 times.
6. Stop engine.
7. Turn brake disc forward 10 times.





8. Use a spring scale to measure the rotation sliding resistance of the hub in the forward direction.
9. Calculate the drag force of the disc brake (difference between of values measured in item 8 and item 1.)
Standard value:
39 N (8 lbs.) or less
78 N (17 lbs.) or less
10. If the drag force of the disc brake exceeds the standard value, disassemble piston and clean piston. Check for corrosion or worn piston seal, and check the sliding condition of the slide pins.
