Worked as it should! Little different with a bleader instead of hoses to bleed. Overall worked great.

Defective. After installing, brake fluid leaded out back of master cylinder between booster and brake master. Faulty from the manufacturer!

Easy to install. Had a little trouble bleeding it but it got β€˜er done.

I bought and correctly installed this cylinder a month ago, and the first time I needed to hit the brakes hard, it failed. I was able to avoid the accident, but when I needed to stop, the brake pedal went all the way to the floor.Having an unreliable braking system is an obvious safety concern. Do NOT buy this part under any circumstances.

Works well and was a lot cheaper than ordering through the shops. Ended up saving $250

Did not work. We brought my car into the shop after replacing it ourselves and not being able to figure it out. At the shop, the tried to bleed the brakes and do everything they could but it's a faulty master brake cylinder. Waste of money.
