BRAKE MASTER CYLINDER(for RHD) REMOVAL

CAUTION / NOTICE / HINT

Note

Make sure to release vacuum from the brake booster assembly before removing the brake master cylinder sub-assembly from the brake booster assembly.

PROCEDURE


  1. DRAIN BRAKE FLUID

    Note

    If brake fluid leaks onto any painted surface, immediately wash it off.

  2. SEPARATE NO. 3 ENGINE ROOM RELAY BLOCK ASSEMBLY


    1. B0072OZ

      Disengage the claw and clamp to separate the No. 3 engine room relay block assembly from the wiring harness clamp bracket.

  3. REMOVE WIRING HARNESS CLAMP BRACKET


    1. B0075PF

      Remove the bolt, nut and wiring harness clamp bracket.

  4. REMOVE BRAKE MASTER CYLINDER SUB-ASSEMBLY


    1. B00757H

      Disengage the clamp and disconnect the connector from the brake master cylinder sub-assembly.

    2. B0073O1

      Using a union nut wrench, disconnect the 2 brake lines from the brake master cylinder sub-assembly.

      Note


      • Do not damage or deform the brake lines.

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

    3. B0076T0C08
      *1 Front No. 2 Brake Tube

      Remove the 2 nuts, wire harness clamp bracket and brake master cylinder sub-assembly from the brake booster assembly.

      Note


      • The brake master cylinder sub-assembly requires careful handling. Do not subject the brake master cylinder sub-assembly to any impact, such as from being dropped. Do not reuse a brake master cylinder sub-assembly that has been dropped.

      • Do not hold the brake master cylinder sub-assembly by the master cylinder piston. Hold the brake master cylinder sub-assembly by its body or its reservoir when carrying it.

      • Do not pull out the master cylinder piston.

      • Do not strike or pinch the master cylinder piston, or cause any damage to the master cylinder piston by any other means.

      • When installing the brake master cylinder sub-assembly to the brake booster assembly, or when removing the brake master cylinder sub-assembly from the brake booster assembly, make sure that the brake master cylinder sub-assembly is kept horizontal or with its tip facing downward (the master cylinder piston is facing upward) to prevent the master cylinder piston from falling out.

      • Do not allow any foreign matter to contaminate the master cylinder piston. If any foreign matter gets on the master cylinder piston, remove it by using a piece of new and dry cloth. Do not use water or detergent. Then apply an even layer of lithium soap base glycol grease around the circumference (sliding part) of the master cylinder piston.

      • Do not use any other types of grease.

      • Make sure to release vacuum from the brake booster assembly before removing the brake master cylinder sub-assembly from the brake booster assembly.

      Tech Tips

      Remove the brake master cylinder sub-assembly while avoiding the front No. 2 brake tube.
