Gotta remember to take actual master cylinder diameter into account too. A smaller cylinder is gonna be easier to apply higher forces with and feel tighter than a larger cylinder but may not move enough volume of fluid to fully actuate large or multiple piston calipers.

They are OEM on my trike. Gravity waves, another Einstein hypothesis confirmed and announced thursday.  www.ligo.caltech.edu/news/ligo20160211"The gravitational waves were detected on September 14, 2015 at 5:51 a.m. Eastern Daylight Time (09:51 UTC) by both of the twin Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA. The LIGO Observatories are funded by the National Science Foundation (NSF), and were conceived, built, and are operated by Caltech and MIT. The discovery, accepted for publication in the journal Physical Review Letters, was made by the LIGO Scientific Collaboration (which includes the GEO Collaboration and the Australian Consortium for Interferometric Gravitational Astronomy) and the Virgo Collaboration using data from the two LIGO detectors. Based on the observed signals, LIGO scientists estimate that the black holes for this event were about 29 and 36 times the mass of the sun, and the event took place 1.3 billion years ago. About 3 times the mass of the sun was converted into gravitational waves in a fraction of a second—with a peak power output about 50 times that of the whole visible universe. By looking at the time of arrival of the signals—the detector in Livingston recorded the event 7 milliseconds before the detector in Hanford—scientists can say that the source was located in the Southern Hemisphere. -snip- At each observatory, the two-and-a-half-mile (4-km) long L-shaped LIGO interferometer uses laser light split into two beams that travel back and forth down the arms (four-foot diameter tubes kept under a near-perfect vacuum). The beams are used to monitor the distance between mirrors precisely positioned at the ends of the arms. According to Einstein’s theory, the distance between the mirrors will change by an infinitesimal amount when a gravitational wave passes by the detector. A change in the lengths of the arms smaller than one-ten-thousandth the diameter of a proton (10x-19 meter) can be detected." |

Hell, I was really excited today with the results that confirmed the existence of Gravity Waves today. That made my day.  Excitement all around!  I have transparent jacketed braided lines all around on my R-trike disk brakes but I don't think mine are stainless. They look more like Kevlar or something. Happy to read someone else was touched by this great scientific news yesterday! Awesome, FrankenMech!! Rather unfortunate that this ground breaking confirmation of the old theory (100 yrs old) has such a low profile... kinda sad actually. This is in the sim. league as the Newton's apple, quantum mechanics, E=mc2, et. al. Really grand, this is. |

Earth shattering and described as a 'Moon shot' or 'Galileo's telescope' etc also, but low key as usual. Basic research is usually seen by the public as wasted $$$ but it never is. Basic research always leads to applications, G-Wave astronomy is just a first application but it is basic research in itself. I was bouncing all day with a huge grin on my face after the news was announced. It is amazing they kept it quiet so well since last September. They are talking about putting another LIDO installation in India, although I think it would be far safer to put it in Australia. Way WAY off topic here but I have also been following progress in Faster Than Light (FTL) technology. Another outcome of Einstein's theories. There is some info here: www.washingtonpost.com/news/post-nation/wp/2014/06/11/this-is-the-amazing-design-for-nasas-star-trek-style-space-ship-the-ixs-enterprise/Check out Dr White's lecture. In my view, the proofs of Einstein's predictions just adds credence to many other things.  |
