I tried it out tonight. Put bike on centre stand & spun the back wheel. Operated the front brake & it didn't slow the back wheel at all. So that website i was reading have got their info wrong. Well i can't believe there's something on the internet thats not true!
Twas a good job i did try it though. Whilst doing it, I noticed that my brake light was on all the time! Then remembered that i adjusted the brake pedal a week ago & didn't adjust the switch. Doh!! So got that sorted out now.
