OEM made in China
Good quality and has worked well so far. This was a General Motors replacement part in a GM Delco box. Inside it says made in China. I probably won’t buy again. Will buy American made if I can find one.

Perfect Factory Replacement
Install was easy, I originally replaced my hydro pump and was still getting fluid contamination. Had to drain my brakes a few times on couple long trip. Finally replace the brake master cylinder and it fixed the problem. Pre-bleeding the master cylinder was the key to eliminating air in the lines.

Great quality
2006 GMC Sierra Duramax. I installed it alongside all new brake lines and hoses, brakes work great and didn’t brake the bank😝.No leaks holds pressure good!

Installed on a 2003 3500 Silverado
Perfect solution for jumpy brake pedal. Dirty master cylinder and hydro boost don't work well together. I replaced my master cylinder with this unit and my brakes are back to buttery smooth with apply and release.

This is a great master cylinder at a fair price when your engine warning light appears!
I have a 2006 GMC Sierra 2500 HD SLE with the 6.0 engine. This was exactly what the doctor ordered! My engine light came on, but this part was perfect and for a very reasonable price!
