Replacing original rear Master cylinder with A Brembo.

[Cookindad]

So I gave it a valiant effort to repair and or replace my tired OLD original rear Master cylinder, NOT happening. Went to a well known 2nd hand cycle parts store and bought a gently used Brembo off a Yamaha. Different bolt pattern. I made a bracket out of some aluminum stock I had laying around. Just about to get it on the bike. Any suggestions or warnings would as always be appreciated.

Have you mounted this yet? Did the angle work out? What about the length of the push rod? Lots of questions! Post pics of it mounted, too, if you would.

Been working at my day job all weekend, I hope to get it all put together Monday. As for the angle, it looks to be very close. I did have to use the original push rod to get the length I needed. I am cautiously optimistic. Victory shall be mine, Pics to follow.

About the only advice I can think of is to be gebtle when you put the bike back on the road. I'm wondering WHAT could have been so wrong with the old one that you felt the need to go a different route instead of rebuilding. ???

Sorry to report this adaptor plate was an epic failure. Major clearance issues all around. I am not defeated, merely challenged!!!!

Found a REAL Direct Replacement Rear Master Cylinder that is plug and play for the 80-83 Old Wing. Brass Body with 45mm mounting holes. Perfect for that project and the best part is the PRICE. No not 150.00, not 100.00 but basically 20 bucks. Down side is it comes from China. You can buy 2 of them for what the kit to rebuild your old one cost. I'm rolling the dice and will advise. For 20 smackeroo's ya just almost can't go wrong. Found a brand new Master Front cylinder same price roughly. Direct replacement. Down side........... if your proportioning valve is questionable (83 Model) you will have to revert to old style no linked brakes. The front is available as a 14 mm piston or 16 mm but the 16mm line mount is on front side. May have to adapt it if that's what you want.
For forty bucks I save 130-170 bucks over rebuilding what may be a questionable rebuildable part. I also consulted a few of the "experts" in Europe and they said the quality has vastly improved on these and they use them as direct replacements as well. Wanna spend a day ripping apart those old ones and rebuilding them? Think I will do that and save em for any anticipated problems. Hope all works out well and I will come back after install and test ride to evaluate.
