Is there such a thing as ABS pump and what is the cost to replace it

Hi Streamer 4u: Yes the ABS does have what you would call a pump. You said the brake light was on. This could be caused by a number of things brake light switch, shorted wires, wheel speed sensors just to name a few. Also the ABS system could be at fault. If you have any question on the testing that was done by your mechanic we would be more than happy to confirm those findings. Feel free to contact us to set up an appointment to come in. Our ASE specialist would be happy to help out. Sincerely Ultimate Performance Team
