Brake Fluid Accumulator: Service and Repair
Depressurizing Hydraulic Accumulator
NOTE:The ABS pump/motor assembly will keep the hydraulic accumulator charged to a pressure between 1600-2000 psi anytime the ignition is in the
ON position. The pump/motor cannot run if the ignition is off or either battery cable is disconnected.
WARNING: The hydraulic accumulator should be depressurized before disassembling any portion of the hydraulic system.
1. Turn ignition switch to the OFF position, or disconnect battery ground cable.
2. Pump brake pedal a minimum of 40 times using approximately 50 pounds of pedal force. Pedal feel should change noticeably when accumulator is
discharged.
3. After a definite increase in pedal effort is felt, pump pedal a few additional times. This will remove all hydraulic pressure from the system.
