Review on ACDelco 12669488 Original Equipment Vacuum by Scott Ward

Revainrating 5 out of 5

Stuck Hard Brake Pedal

Replaced original vacuum pump on 2014 Silverado 5.3 80,500 miles. The brake pedal was very stiff and the brake pedal travel was minimal. The brakes were basically 0% or 100%. Replacing the pump was a chore but worth the savings and getting the brakes working properly again! AC Delco spare parts at prices below the dealers and in the spare parts warehouse!
