ACDelco GM Original Equipment 175-0634 Brake Master Cylinder with Seal and Retainer

All is good. Comes with fluid bowl gaskets and O-ring. Make sure you bench bleed it before mounting.

Did the job just as it should bought to replace a junk autozone master cylinder that lasted 2 weeks. I have a good brake pedal now

Good

I purchased a master cylinder for my car, but unfortunately, it failed within just two days. Initially, I attributed it to bad luck with that specific part, prompting me to request a replacement. To my dismay, the replacement also failed after only a few days of normal car driving. Growing increasingly frustrated with the recurring issues, I decided to pursue a refund. However, despite more than 35 days having passed, I am still awaiting the refund. It's noteworthy that Amazon indicates ACDelco received the returned part 30 days ago, yet the refund has not been issued. This prolonged delay adds to the dissatisfaction of my overall experience.

2007 Equinox, original equipment was leaking brake fluid into the brake booster. Part arrived on time and I installed it promptly and have not had any problems.

2008 Chevrolet Equinox

This part fit perfect I'm really happy with this
