Fixed the issue with the hard brake pedal
The brake pedal in my Chevrolet Malibu (2014) was hard, especially at low revs, as if the brake booster wasn't working. Based on the information on the Internet, the issue was identified to be with the vacuum pump on the engine (it was also noisy). This pump was a perfect fit and a direct replacement - and now everything is back to normal. The replacement itself was pretty easy, and the new pump comes with the gasket and bolts, which is great.I opened up the old pump, and it was absolutely gutted inside, no wonder it was making terrible noises and did not provide vacuum.

This is the exact replacement OEM part at a great price.
Watch the You tube videos regarding the GM vacuum pump failure. I replaced this part at 50,000 miles as a precautionary measure. The part I removed had visible wear on the inside plate however the screen was clean and there was no damage or wear to the outside propeller. With this part causing catastrophic engine failure it is cheap insurance.

Fits perfect!
Fits perfect for my 2013 Cadillac Ats. If you are handy and have patience, you can do this diy. If you take it to dealer or a shop you're looking at about $1000.I installed it myself and took 3-4 hrs. My old one grinded it self up and shattered on the inside. Luckily no metal shavings went into the engine valves or would have been catastrophic. This the importance of keeping up with oil change.This one I bought on Amazon has been running good since installed a few months now.
