Master cylinder?? Issue.

When I purchased the car it had all new IT factory style lines and a bolt on top dual master cylinder. The replacement master cylinder ( Right Stuff Detail) is basically reversed from the factory issue. Small pot in front 9/16 thread and large rear pot 1/2.

I hooked the lines up as were threaded and so with that the small pot 9/16th thread with residual valve was feeding the front brakes and large rear pot with 1/2 thread feeding the rear drums.

In other words the ports were as stock but the pots in the master are reversed from the stock 69

Why I didn’t consider all that at time of install who knows? As I said there were some bad times for a few years.

I still don’t understand why they didn’t smoke ? I may have been wasted but my wife wasn’t when she was riding with me and she’s knowledgeable enough to notice stuff like that.

Reversing the lines with the help of some adapters seems to have cured the problem just went for a short road test and it seems good.

Thanks to Everyone Again
