So I ordered this part in May last year and put off writing a review because obviously I wanted to pre-use this part. I had to request a replacement after my first order as I received a faulty master cylinder. Then they sent me a replacement and now I've had it for a little over a year. Recently it started to fail and just today my brakes completely locked up on the way to the gym. I know these parts will be remanufactured but I expect them to last a little over a year. I'm not very happy with it and I think the reliability and quality could be better.
