Dear all,
I am in the process of renewing stuff around the front of my 400N Superdream, as the wheel omits this strange neither hissing, nor dragging sound, which I don't like much. I have already replaced the wheel bearings, as they were all wobbly, taken out the speedo dog, straightened it, taken the speedo gear apart as much, as I could and cleaned the junk from there too. the rotor is touching the pads slightly, so I have taken the brake apart (as far as I could go without completely dismantling it, basically splitting it to two), pumped out the master cylinder, sanded it with a 2000 grade paper and pushed it back, which was very hard to do without causing damage to parts. Also whilst there I noticed, that one of the axles, or shafts of the brake caliper (or what to call them) was binding, so I have removed that, cleaned it, re-greased, now it is moving in it's housing a bit freer, but upon reassembly the rotor touches the pads all the same. I have taken the bike for a test ride, and the strange noise, although is not so loud anymore, is still there. Now on the cmsnl site I have had a look at the diagrams of the wheels, and it looks like, there are some spacing shims underneath the rotors, which I definetely do not have on mine. Could this cause the constant dragging? If I put something there, washers, etc., would that foul the worn (but still very good) pads? If the spacers are necessary, does anybody know their thickness? Would it be enough to put two spacers underneath the brake caliper bolts, or is that a big risk of the damn thing dislodging and jamming the front wheel on the motorway?
Thanks!
Gabriel
