CAUTION / NOTICE / HINT

NOTICE:

  • After replacing the brake booster with master cylinder assembly, make sure to perform update ECU security key.
  • After performing the update ECU security key procedure, make sure to perform the initialization procedure for when the cable has been disconnected and reconnected to the negative (-) auxiliary battery terminal.

PROCEDURE

1. INSTALL BRAKE BOOSTER GASKET

2. INSTALL BRAKE BOOSTER WITH MASTER CYLINDER ASSEMBLY

(1) Install the brake booster with master cylinder assembly with the 4 nuts.

Torque:

12.7 N·m {130 kgf·cm, 9 ft·lbf}

NOTICE:

  • Tighten the nuts in the order shown in the illustration.
  • Do not kink or damage the brake lines.
