Got my wheels back from the powder coaters and new tyres are fitted. I asked the powder coaters to make sure the threads where masked and also the face of the hub where the discs settle. He hasn't done that. So my question is:

Will the thickness of the powder coat mean the discs will drag in the caliper and should I carefully file the coating back to metal where the disc meets the hub?

no you should call them first and ask them nicely to sort it out

I have heard of people having problems where care has not been taken when powdercoating rims and the face to which the disks mate has been contaminated. It can give the "pulsing" effect when braking and lead to uneven disk wear.
I think you need to make sure that it is very flat.

And I agree with Flatlander - they should sort it out

Yep, I would agree with the above. The previous owner of my wheels had them podercoated, and they had done the insides where the bearings slot in. Suffice to say it took 4 hours to get them out!

Without wishing to sound wise after the fact, that's often the difference between the cheap place and the more expensive one (not always true of course). The cheap guy skimps on the prep to maintain his margins.

I've recently sent some wheels to Triple-S in Bingley and I know from past experience that they will mask everything that needs to be masked and do a top quality job. You do pay more, but in my view it's worth it.

But yes, it's their responsibility to sort them out. And you really don't want to be seating disc carriers onto powder coat. It all depends how inconvenient it is to return them, of course. I've used carefully applied Nitromors to remove errant powder coat before (before I discovered Triple-S, that is).

Thanks chaps.

i masked up mt mates wheel using silicone plugs and high heat tape
got them from here

they sand blasted the wheels gave me them back and i don the prep , masked the rotor areas pluged all the screw holes and gave then back for coating
£40 / wheel and was a freat job

I would be a bit worried if I returned them how they would remove the coating. They sound like a bunch of cowboys (I would expect them to at least have the common sense to plug the threads) so if they attack the mounting face with an sander - bang goes the precision machined face and hello pulsing brakes.

Thanks all - probably wasn't as bad as I may have suggested. The threads were fine but some of the coating had strayed onto the some of machined surfaces where the disc carrier fits. Some careful rubbing with course grit paper brought it off and all looks ok. Road test soon.

Thanks for the advice - as usual we learn as we go along. Could have been an expensive mistake though.

You can often remove powder coating from disc mounting faces etc..with a razor blade, just be careful not to dig into the mating face as the razor blade will take alloy off, but done carefully it works a treat and is very quick
