### ⭐⭐⭐⭐⭐ Good fit Cadillac ATS
*by J***2 on November 21, 2025*

Perfect replacement for 2014 Cadillac ATS

### ⭐⭐⭐⭐⭐ Fixed the issue with the hard brake pedal
*by L***. on July 6, 2024*

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.
