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.

  1. 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.

  1. 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.

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

CAUTION:
