CAUTION: Union bolt

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 wheel 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.
Do not spill or splash brake fluid on painted surfaces. Brake fluid may damage paint. 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-17, "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

Remove wheels and tires using power tool. Refer to WT-47, "Removal and Installation".
Drain brake fluid. Refer to BR-17, "Drain and Refill".
Loosen the flare nut with suitable tool 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.

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.

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.

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.

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

CAUTION:

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

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

CAUTION:

CAUTION:

Do not scratch the flare nut and the brake tube.

Refill with new brake fluid and perform the air bleeding. Refer to BR-17, "Bleeding Brake System".

CAUTION:

Do not reuse drained brake fluid.

Install the wheels and tires. Refer to WT-47, "Removal and Installation".
