going to take it up to show Chris Sadd this morning, I'm just a bit worried about how thin it is... [~3.4mm]

Corrado usually has them in stock.......

You would need to be careful skimming it flat again as it would then become varying thicknesses of disc..... which may cause as many problems as it solves....


best bet is a new one and then look on Ebay for a clock mechanism.... fix it to the old disc in the centre - and voila....... a wall clock for your garage!

:lol: probably all it is of use for...
took the disc to CSE, it wasn't warped, but the thickness varied by 0.1mm.... so a new one it is. will get in touch with corrado

after talking with Angry Bloke tonight, who is has been fitting the same to his bike, I am going to check the relationship between the disc and the pad faces, I suspect they may not be in line consistently, and some shimming may be required...
I will also look at the disc, good point about burred holes, roughly checking in situ with a steel rule it seemed ok, certainly no worse than the one on my bike, which works fine, and has done for 000s of miles
On my disc brake, when the wheel is turned when bike is on the stand the disc is rubbing on the pads. I'm guessing this should not be the case, am I right? The wheel should turn freely, right?? What's the fix??

there'll always be some drag on a disc brake, but the wheel should be able to spin at least one revolution fairly freely by hand. If the stiffness is uniform, check that the pistons are not sticking, and that the caliper can move freely. If it is in one place suspect warped, or uneven disc, or the way the caliper sits on the bracket and lines up with the disc.

btw, got a new disc from corrado for my mate, he now has a perfect front brake :D
