Unless otherwise specified, the hydraulic accumulator should be de-pressurized before disassembling any portion of the hydraulic brake system.
- With the ignition OFF , pump the brake pedal a minimum of 40 times, using approximately 50 lbs. (222 N) pedal force. A noticeable change in pedal feel will occur when the accumulator is discharged.
- When a definite increase in pedal effort is felt, stroke the pedal a few additional times. This should remove all hydraulic pressure from the system.
