So I have a Croix de fer and have changed out the brakes with trp hy/rd's the front one works ok but has quite long lever throw, and shudders under heavy breaking. The rear bottoms out on the bar before locking the wheel out. I have used compressionless outers with very little improvement. I am wondering as I am using some older levers (9 speed tiagra) if the throw was wrong, I even tried this (https://www.youtube.com/watch?v=8aBa3sGUUhs
) with little effect. Any other ideas, only used to rim brakes so am worried I may be missing something obvious (have centred calliper etc already a few times, nil effect).
