ABS Pump

What is a ABS Pump?
The ABS pump is part of the Antilock Braking System (ABS). The pump provides pressure to the brakes. After the ABS ECU has detected wheel slip it signals for the valves to open to release the brake, the pump restores braking pressure once the valve closes. It is an integral part of the system and is controlled by the ECU.

Failing ABS pumps can have different symptoms. Generally if you notice changes in the response of the braking pedal there could be an issue with the pump.
What problems can be caused by this part?

Brake pedal unresponsive

The brake pedal doesn't respond to pressure in the same way as it did, it doesn't depress or return in the same way and feels like it's not properly connected to the brakes anymore.

ABS warning light shows on dashboard

The ABS (Antilock braking system) warning light has appeared on the dashboard and stays illuminated while driving.

Car skids and brakes lock up when braking hard

When pressing the brakes hard in an emergency stop situation the wheels lock up and the car skids along rather than stop quickly in a straight line.

Brakes making a clicking sound

When you apply pressure to the brake pedal there is a clicking or tapping sound. The sound can be loud or quiet and usually won't be felt through the pedal itself. It will usually sound like it's coming from one of the corners of the car. The clicking will usually increase or decrease in frequency with the speed of the car, ie it will click aster at higher speeds.
