Advise on upgrading brake lines and replacement radial master cylinder (Interested in Linking Brakes!)

Postby 81GL1100RMD28262 » Wed May 06, 2015 12:57 am



I am in the process of upgrading my factory original brake lines and I am wanting to link the front and rear together and operate everything from a 19mm BremboRCS19 or a Shindy PART # 17-656/B/G/K (19mm Piston diameter).

Brembo cost $346 vs the Shindy @ $203 on Amazon http://www.amazon.com/Shindy-17-656B-Ra ... B0013LEZQ0

Any disadvantages to using the Shindy? Also, I am trying to link the front and rear brakes together and would greatly appreciate any advice or links on how to video.

Thanks in advance for your help!

Ryan

the 83 has a linked system rear and one front caliper. I'd find an 83 system and use it. Are you trying to eliminate the rear foot pedal??

Yes, I am trying to remove the foot brake and run everything off one leaver. This bike has dual front brake calipers and one single rear.

I don't know how you would do that safely without having a proportioning valve or something. Check out the systems on newer bikes with brakes like that. They are pretty complicated systems. My buddy has a cbr1100 super blackbird that has linked brakes like that. The first thing I would do with a bike like that is yank that crap off and run them separate like they should be. Its safer and you have more control of your brakes in my opinion. If your going to link them you only want like 20 percent of the braking force to go to the rear or on a hard stop your rear will lock up.

I agree with sleepy. In order to run everything off of one lever you are going to need some type of way to proportion the amount of force to each brake. I'm not sure you would be able to do that with anything that is currently available. I would assume you would have to engineer some type of valve. I also agree with sleepy that it is safer to have a 2 way system. If one fails you can still stop if you only have one lever and the valve fails or it doesn't work then you have no brakes.


Thanks to all who answer and help. It is greatly appreciated!
