  • Do not allow any foreign matter such as dirt or dust to enter the brake lines from the connecting parts.
  • Be careful not to allow any brake fluid to enter the connector.
  • Do not hold the brake actuator with bracket by the connector.
  • Do not drop the brake actuator with bracket when carrying it.

HINT:

Install the brake actuator with bracket while avoiding the brake lines.

(b) Tighten the 2 bolts and nut in the order shown in the illustration.

Torque:

19 N·m {194 kgf·cm, 14 ft·lbf}

(c) Engage the clamp to install a new brake tube clamp.

(d) Return the front brake tube to its original position.

NOTICE:

Do not apply excessive force to the front brake tube.

(e) Temporarily install the front brake tube to the front flexible hose.

NOTICE:

  • Do not kink or damage the front brake tube.
  • Do not allow any foreign matter such as dirt or dust to enter the front brake tube from the connecting parts.

(f) Engage the clamp to connect the front brake tube.

NOTICE:

Do not kink or damage the front brake tube.

(g) Temporarily tighten the 2 brake lines to the correct position on the brake actuator assembly as shown in the illustration.

NOTICE:

  • Do not kink or damage the brake lines.
  • Do not allow any foreign matter such as dirt or dust to enter the brake lines from the connecting parts.
