Hopefully I'm understanding your question and the answer would be no. When you pull the front brake lever it activates the front right brake caliper. If you step on the rear brake the front left brake caliper and the rear brake caliper are linked and work together. Think opinions may vary on the rear master cylinder rebuild. Some will say yes no problem. But when I asked about the proportioning valve I never got an answer. As far as I know that part of the rear mc can't be accessed or rebuilt. I opted to replace the rear mc rather than guess the proportioning valve was ok (it may have well been ok). But my all my calipers, slave and master cylinders needed rebuilt and the brake pads/lines replaced so at that point I wasn't going to skimp out while I had the bike torn that far down. I had to pull the right header and the exhaust from the crossover back off the bike along with removing a lot of heat shields. It probably took me 10x longer than any shop mechanic would take but I ceramic painted my header that was starting to look rusty and used high temp paint on the rest of the exhaust. Be careful if you go to remove the header. I snapped a stud while trying to unbolt it. Hardly put any pressure on it. Had to replace a stud. Good luck with that rear master cylinder. Anybody who has done one on a 1500 knows the pain :D

thank you so much for your reply. that's a vast amount of information. I did a very thorough brake bleeding of the system today. the brakes are working a lot better than they have been. it had a lot of hair in it, I'm suspect about the master cylinder. we'll see how long I keep these brakes working the way they are now. again thank you for your reply.

Thats a good idea. See how your brakes feel. Only work on the rear mc if you have to. :D

Is there a way to adjust the front brake freeplay? Maybe I am missing something, but I can't seem to find it in any of the service manuals.

Did you mean free play at front brake lever?

Yes I do. There is too much play there now before the brake takes affect....

If you have OEM brake levers then I am stumped too. The lever has brass bushing insert that could wear some and the lever pushes on the piston to the front brake master cylinder.
