Purpose of using 25744426:

 
  • Restore Brake Pressure

    • When the ABS modulator reduces pressure to a wheel that’s locking, the actuator pump re-pressurizes the brake fluid so braking can continue effectively.

  • Maintain Continuous ABS Operation

    • During rapid ABS pulses, fluid is constantly released and re-pressurized. The pump ensures that pressure is available at all times.

  • Work with Hydraulic Modulator

    • The pump is part of the hydraulic control unit (HCU) that opens/closes solenoid valves to adjust pressure to each wheel.


Sings of Bad ABS Actuator Pump 25744426:

ABS warning light stays on

Brakes lock up during hard stops
Pump motor runs continuously or not at all
Brake pedal feels unusually soft or pulsates
ABS codes stored in the system (C-codes, e.g., C0271, C0272, C1251)
