I have a question for anyone who may have put the XBRR master cylinder on a Lightning. My specific question is about the stock brake line -- will it work, or do I need to go with a different line? It does not look like to me that the stock line will work because the banjo bolts have a very different mounting angle. Like anyone, I want to minimize down time and finish the change the same day I start it, so I'd appreciate any firsthand knowledge that could be shared. I'm going to change to the XBRR master cylinder, keep the stock caliper, and swap to the Lyndall Golds. It's a little aggravating that my beater '01 Blast has much better brake feel than my 9S... | ||

Confirmed. You will have to fab a mounting bracket, but I believe that is the only issue. | ||

Just a word of warning, the XBRR master cylinder is a different piston diameter than stock. It is designed to work with the 8 piston caliper. The XBRR master cylinder is a 14mm and the XB setup is a 12.7mm. If you use the XBRR setup with the 6 piston caliper the leverage required for hard braking will go through the roof. You'll need to switch calipers also to get the full advantage. The XBRR setup is the same as the 1125R so the price is significantly less due to mass production. Schmitty | ||

+1 to what Mr Schmitt said. I've been told that you need to do a complete swap of caliper and master cylinder to do this right. EDIT: Does the XBRR master have a brake light switch? You'd probably be better off, cost wise, going to the 1125r master and caliper. That's what my winter project is. (Message edited by buellinachinashop on July 15, 2008) | ||

We put an RR master on a stock lighting brake setup. The lever effort was minimal but going the full boat would be 1st choice. | ||

I appreciate the info so far, but I'm feeling a need to clarify a bit. My question is whether the stock XB9S brake line will work with the XBRR master cylinder. All of my many other questions about the setup were answered by Josh at Cycle Connection, who sold it to me for an incredible price. It hit my door, shipping and all, for under $100. I'd be amazed if the 1125R stock part costs less. The stock cylinder has the banjo bolt more or less horizontal, and the brake line fitting has an angle of about 45 degrees. The XBRR master has the banjo bolt maybe 15 or 20 degrees off vertical. I was hoping that someone here could tell me from first-hand knowledge that there is enough slack/play in the stock brake line for this to work. I'm not sure from just looking, and as I said in my first post, I need to finish this in one fell swoop (gas $$$, 60 mile work commute, you know...). The brake light switch was already installed when it arrived. It is a linear type master cylinder, which if memory serves, the 1125R's is not. And, to be perfectly honest, I demo'd an 1125, and I was not blown away with the brakes (the engine is a story for another day). In fact, the Uly that I rode on the same day had much better lever feel and initial bite. As for the leverage/piston diameter differences, I believe that will work in my favor for various reasons. Other threads here have made mention of this setup working well, I prefer a very firm brake feel, and both genetics and career field contribute to my stronger than average grip strength. I'm hoping to have this project finished soon. I'll report the results as soon as I can. One last question -- should I rough up my rotor ( I have a small ball hone) when I change to the Lyndall's, or just throw them on and go? |
