REMOVAL & INSTALLATION



See Figures 1 and 2

The modulator, accumulator and power unit must be bled if any of their lines are removed or loosened during repairs or if any component is replaced. Bleeding can ONLY be accomplished with Honda's ALB scan tool and the special bleeder T-wrench or their equivalents. DO NOT attempt to use any other procedures or tools to bleed the high pressure components.

Accord
  1. If equipped with an air bag, disconnect the negative battery cable and properly disable the Supplemental Restraint System (SRS), as detailed in Chassis Electrical .
  2.  
  3. Relieve the system pressure using the bleeder T-wrench.

DISPOSAL



See Figure 3


CAUTION
The accumulator contains high-pressure nitrogen gas, even after fluid pressure is relieved. Do not puncture or expose to heat or flame. Do not attempt to disassemble the accumulator. Failure to follow correct safety precautions may cause the accumulator to explode, resulting in severe injury and/or property damage. The accumulator must be correctly relieved of internal pressure before disposal.

  1. After removal, secure the neck of the accumulator in a vise; the relief plug should point straight up.
  2.

Fig. Fig. 3: Release the pressure from the accumulator before disposal

  1. Wear goggles or other face and eye protection. The escaping gas, although non-toxic, can carry dust and debris with it.
  2.  
  3. Slowly turn the relief plug 3 1 / 2 turns; wait 3 minutes for all pressurized gas to escape.
  4.  

Nitrogen is an inert, non-flammable, non-toxic gas. It is safe for release into the atmosphere.

  1. Slowly remove the relief plug completely. Dispose of the accumulator unit.
  2.
