Maguras ARE a pain in the arse to set up correctly. Listen to Adam, he knows best. It is a bit of an art, and if you've done it a few times you definitely get the knack for it. I wouldn't really recommend the way TomR said, just because if your pads don't retract normally then you'll have problems with the TPA wound in like he said. If you're really stuck, a very easy way is to take the tyre off and put the wheel back in, that way you can adjust the maguras without the tyre being in the way. Wind the TPA all the way OUT (pads furthest from the rim). Use some 2p coins between the pads and the rim, they're the right sort of thickness. Then adjust it so everything's nice and parallel and do everything up tight. The good news is that once you set them up properly, if you do the bolts up nice and tight, you shouldn't need to touch them ever again. P.S. From what you were saying in the other topic about the back brake being quite spongy - have you got the same pads front and rear?
