Quoted from RobPearce-

Well, we're getting into specialist tool territory here. You need a dial gauge with appropriate mounting. You would use that to measure the run-out of the disc at a few radii. Then you'd take the disc off and use the dial gauge to measure run-out of the hub, back and front.

Of course, this might all just show that there really isn't any to speak of. Is there any play in the bearings? Did you set them by the book? How are you spinning the disc? Is the noise when you're driving?

OK that sounds quite complicated, the bearings where fitted by my mechanic friend they were new so no play, the noise happens when you are driving but only after you have used the brakes a few times.

Chunky,

Out of interest, where did you get the stub axles and did you manage to set the bearing end-float OK? 

I bought a pair of stubs from Rimmers last month. After much head-scratching, eventually found they were too long by about 2.5mm. With the castellated hub nut fully tightened there was still loads of lateral hub movement. Just worth checking.

I got the stub axles from James Paddock because I have had a run in with Rimmers before and I will not use them now!! customer service stinks! I bought a roof from them which does not fit at all, their answer "well we have sold 10 of them and nobody has come back" which I understand now is their standard answer to everything talking of others! 

thanks

Quoted from RobPearce-

A common cause of brand new discs appearing to be out of true is failure to properly clean the back of the hub when fitting. Also, check the condition of the hub for run-out and the alignment of the bearings.

they were brand new hubs and discs. i can check the alignment of the bearings, is there a way of doing this?? thanks 

I think i should explain myself a little better, the squeaking come when your foot is off the brake and when you apply the brakes the noise stops. i am just wondering if there is anything that i can do to stop this?

many thanks John 

Yes they have been fitted and new brake pads and discs, its the disc that does not run true rubbing the pads while turning causing an bird like squeak... most annoying 

I have replaced the front vertical links, stub axle, hubs and brake calipers and discs. but still they don,t run true and I have squeaky sound as they rub against the brake shoes. Does anybody have a remedy of how I can sort this please??
