This post is a footnote to my earlier thread concerning my attempt to install a new TRW brake master cylinder in my project car. As soon as I poured fluid in the reservoir it started to drip out from a faulty seal between the reservoir and the metal cylinder.
I contacted the supplier who informed me that they buy direct from TRW. They went on to say that they didn't have "too many problems with them. Only 9 failures out of the 365 master cylinders they've sold over the past year". Nine out of 365 is 2.5% I consider that unacceptable on a safety related component.
I bring this up not to alert you to some looming disaster. The seal that failed on my MC was a static seal. A leak there may ruin your paint but it's not likely to lead to a catastrophic brake failure. However, it is an alarming statement that a 2.5% failure rate on new brake assemblies is somehow acceptable.
I encourage you to report ANY brake component quality problem to the attention of your vendor and ask them to forward the complaint to their supplier. If I hadn't spoken up, my vendor would only know of 8 failures out of 365.
