The master cylinder on my 1971 1.7 is leaking. I searched and haven't been able to find a DIY fix. From what I have read, the master cylinder can't be rebuilt any longer, I also read somewhere that a 911 master is an improvement over the 914. So, I am looking for the how to DIY and where should I purchase a new one? TIA

No, the 911 19mm MC is sized for the 911/914-6 brake system, while the 17mm is sized for the 914's brakes - so it's not an improvement, just cheaper since they're more made for all the 911s out there.
Try to stick with an OEM ATE brand from one of our member vendors (PMB, GPR, etc.) or a Porsche dealer or reputable Porsche parts retailer, There are knock-off FTE out there too, but IMHO not worth the lower cost for lower quality & lesser parts life. There is a great explanatory thread on 914world about the 19mm MCs not being better, & 17mm being best for 914/4s - but I've lost that link to the topic, so maybe someone else can add it below. ...or PM or email to Eric Shea at PMB for the info on this subject..... http://www.pmbperformance.com/teener.html (IMG:style_emoticons/default/welcome.png) & Good Luck!
