Thought i would add my brake problem to this topic. Ive had a hope mono trial on the front for around a month and its been fine till last night. I was out on a ride and for 2 hours it was fine, was gapping to front wheel and going up to front quite happily. Then all of a sudden as i landed on the front wheel it locked hard, screamed like a pig and almost launched me over the fornt. Now, its does this everytime, screams, judders and has lost all modulation. Any help, all i can think of is a stuck piston????
