Eclipse FWD L4-1997cc 2.0L DOHC MFI (1997)
Vacuum Brake Booster: Adjustments
Clearance Between Push Rod And Primary Piston
Calculate Clearance A
Adjust the clearance "A" between the brake booster push rod and primary piston by calculating the clearance "A" from the "B", "C" and "D"
measurements: A = B - C - D
Clearance "A" is 0.65 - 0.85 mm (0.0256 - 0.0335 inches)
NOTE: When brake booster negative pressure 67 kPa (9.7 psi) is applied, the clearance value will become 0.1 - 0.3 mm (0.004 - 0.012 inches)
If the clearance is not within the standard value range, turn the push rod screw to achieve desired length.
