Removal

Hydraulic control unit (HCU) assembly

1. Disconnect the negative battery cable from the battery

2. Pill up the locker to remove the unit connector.

3. Disconnect the six brake lines (2 inlet and 4 outlet) using a flare nut wrench. Be prepared to catch escaping

brake fluid. Temporarily seal open brake lines with plastic caps or equivalent.

4. Remove hydraulic control unit bracket bolts and nut on the vehicle remove unit bracket.

5. Temporarily seal open brake line ports with plastic plugs or equivalent.

6. Store the hydraulic control unit in a protective container while it is being serviced.

Installation

Hydraulic control unit (HCU) assembly

1. Install Hydraulic Control Unit into position and tighten the bolts and nut.

Tightening torque: 6~9 lb-ft (8~12 N-m, 80~120 kg-cm)

2. Reconnect six brake lines. Be certain that the four lower outlet lines have been connected to the correct

ports. Tighten the nuts to specification.

Tightening torque: 9~16 lb-ft (12~22 N-m, 1.3~2.2 kg-m)

3. To hydraulic control unit and connect Hydraulic Control Unit connector. Be certain connectors are fully

wire to its original position after repair.

Installation

1. Install the sensor rotor with a suitable tool.

Inspection

1. Measure the resistance of the wheel speed sensor.

Resistance : 1.0~1.3 KΩ

2. Replace the wheel speed sensor if necessary.

Inspection

1. Check rotor for damage.

2. Check if gap between rotor and sensor meets the specified value.

Gap : 0.0287~0.0578 in (0.73~1.47 mm)
