  10. REMOVE BRAKE MASTER CYLINDER SUB-ASSEMBLY


    1. A001XJ8

      Disengage the clamp and disconnect the reservoir level switch connector.

    2. A001XGB

      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 during the removal procedure.

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

      Note


      • The brake master cylinder sub-assembly requires careful handling. Do not drop or subject the brake master cylinder sub-assembly to any impact. 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 brake master cylinder reservoir assembly 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 cloth and 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 type of grease or fluid.

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

    5. Remove the brake master cylinder O-ring from the brake master cylinder sub-assembly.
