REMOVAL SERVICE POINT
   
Disengage the claw of arrow 1 and arrow 2 in sequence, then remove the reservoir protector.
   
Insert vacuum hose with its paint mark facing upward.
   
  1. Use the vacuum pump to measure dimension "A" applying a negative pressure of 66.7 kPa to the brake booster.
  2. Standard value (A): 10.15 - 10.40 mm
    NOTE: When a negative pressure of 66.7 kPa is not applied to the brake booster, the push rod protrusion amount (A) should be 8.85 - 9.10 mm.
       
    1. If the protrusion amount is not within the standard value range, adjust the push rod length by turning the push rod. Use the special tool push rod adjusting socket (MB991568) to turn the push rod while holding the rod spline with angle-nose pliers.
       
    Insert the reservoir hose with its paint mark facing front of the vehicle.
       
    Install the reservoir protector with its arrow mark facing behind the vehicle.
