CAUTION:

• All hoses and piping (tubes) must be free from excessive bending, twisting and pulling.
• Make sure there is no interference with other parts when turning steering both clockwise and counterclockwise.
• The brake piping is an important safety part. If a brake fluid leak is detected, always disassemble the parts. Replace applicable part with a new one, if necessary.
• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is splashed on painted areas, wash it away with water immediately.
• Do not bend or twist brake hose sharply, or strongly pull it.
• When removing components, cover connections so that no dirt, dust, or other foreign matter gets in.
• Do not reuse drained brake fluid.
• After installation of the ABS actuator and electric unit (control unit), refill brake system with new brake fluid. Then bleed the air from the system. Refer to BR "Bleeding Brake System".

Front : Removal and Installation

NOTE: When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spilling.

REMOVAL

1. Remove the wheel and tire assemblies using power tool. Refer to WT "Adjustment".
2. Drain brake fluid. Refer to BR "Draining".
3. Loosen the flare nut with a flare nut wrench and separate the brake pipe from the hose.

CAUTION:

• Do not scratch the flare nut and the brake pipe.
• All brake hoses and pipes must be free from excessive bending, twisting and pulling.

4. Remove the union bolt and the brake hose from the brake caliper assembly. Remove and discard the copper sealing washers.

   CAUTION: Do not reuse copper sealing washers.

5. Remove the lock plate and remove the brake hose.

INSTALLATION

CAUTION: Do not allow foreign matter (e.g. dust) and oils other than brake fluid to enter the reservoir tank.

1. Assemble the union bolt (A) and the copper sealing washers (1) to the brake hose and install it as an assembly to the caliper.

   Align the brake hose L-pin by aligning it with the brake caliper assembly hole, and tighten the union bolt (1) to the specified torque.

   CAUTION: Do not reuse copper sealing washers.

2. Install the brake pipe to the brake hose, temporarily tighten the flare nut by hand until it does not rotate further, and fix the brake hose to the bracket with the lock plate.

   CAUTION: Check that the brake hoses and pipes are not bent or twisted.

3. Tighten the flare nut to the specified torque with a flare nut torque wrench.

   CAUTION: Do not scratch the flare nut and the brake tube.

4. Refill with new brake fluid and perform the air bleeding. Refer to BR "Bleeding Brake System".

   CAUTION: Do not reuse drained brake fluid.

5. Install the wheel and tire assemblies to the vehicle. Refer to WT "Adjustment".
6. Perform inspection after installation. Refer to BR "FRONT : Inspection".

Front : Inspection

INSPECTION AFTER INSTALLATION

1. Check the brake hoses and tubes for the following: no scratches; no twist and deformation; no interference with other components when steering the steering wheel; no looseness at connections.

   CAUTION: Clearance with brake hose and each parts being secured more than 10 mm (0.39 in) in unladen condition*.

   *: Fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and mats are in designated positions.

2. Depress the brake pedal with a force of 785 N (80.1 kg-f, 176.5 lb-f) and hold down the pedal for approximately 5 seconds with the engine running. Check for any fluid leakage.

   CAUTION: Retighten the applicable connection to the specified torque and repair any abnormal (damaged, worn or deformed) part if any brake fluid leakage is present.
