Review on ACDelco 174 1230 Original Equipment Cylinder by Miguel Yurco

Inexpensive for a genuine part for my 2011 CTS. It was packaged very well and was easy to assemble. It's not like you need a quart or so of new brake fluid just to fill the reservoir on that new master cylinder. So make sure you have enough on hand to fill it up, bleed it on the bench and bleed the entire braking system. Deducted a star because it doesn't include the bleed kit that comes with almost every replacement master cylinder I've seen for sale. I just bought 3/8" OD pipe from a hardware store and got it working.
