Review on Dorman M630031 Brake Master Cylinder for Cadillac, Chevrolet, and GMC Models by Larry Simpson

I noticed that my 2000 Silverado's original master cylinder was leaking so I decided to replace it. I chose this master cylinder because I trust the Dorman brand and the price was lower than the local auto parts stores. Appears to be of good quality and tight. Don't forget to deflate it first by following the instructions that come with it. It's been installed for about a month and works flawlessly.
