Righto, I've got some Heatsink Reds on my Ta26, and on a DX32. At first, they were beasts, loads of lock and bite and noise. I got a flat yesterday, sorted it and clipped me brakes back on, and now theyre absolutely shite. Theres no lock or bite or noise, and I cannot, no matter what I do, get one of the pads to hit square. What could I be doing wrong? Its really frustrating, cos this is the first and probably last night I'm gonna get to ride for the next couple of weeks. Should I grind a bit of the pad off to make it square? Is there any decent tutorials for setting a v brake up for trials use? I really don't know whats going on!
