Review on 👍 ACDelco GM Original Equipment 174-1152 Brake Master Cylinder Assembly: Superior Quality and Performance by Reza Shoecraft

Exactly the same as the factory unit. I lost braking power and noticed that I was leaking brake fluid through the front of the brake booster and the back of the master cylinder. I bought a new one because it said it was a new factory product that was OEM. In fact it was. There was another post about it here that said BOSCH below, but the bearing block I took out of my truck had the same BOSCH stamped on it. Installed very easily and restored braking performance. The price is better than any parts store for what you get. All sold in stores were rebuilt; for another $30. Great value for money.
