Review on ACDelco 12669488 Original Equipment Vacuum by Demarco Vonk

Revainrating 5 out of 5

Good replacement for the stock pump

Put this on my 2015 Silverado to fix a hard brake pedal/service brake problem. It took me a while (4.5 hours) but I made it myself using basic household tools! The brakes work much better at low revs, when reversing or in traffic. FYI, you don't have to drain the oil, but it will leak out of the engine a little when it's removed.

Pros
  • Excellent overall performance
Cons
  • Not as thick as other picks
