I use the rear brake quite alot helps to settle the brake mid corner or if I need to scrub of a little more speed as I am tipping it in
By the way my rear brake failed on saturday morning
I was going down hill and the bike was working hard, pulled in the cluch and the bike came to a fairley quick halt.
Turns out the rear master cyclender sezied up
Never mind £35 quid later new one fitted
