Problem with front disc brake aligment.

Postby Delikwent » 30 Aug 2020, 10:29am

Hi. My first post on the forum.

I have converted my hybrid bike into front motor 250W ebike (ebay kit). The problem that I am facing is that the disc is misaligned with the brake by around 5mm.

I bought M10 washers in order to wider the fork a wee bit, but the washers do not fit.

Called the Halfords and the guy recommended "disc brake conversion kit".

Did some research but did not find anything useful. The fork is not v-brake compatible.

Any suggestions or advice?

Will upload the misalignment picture when back at home.

Cheers.

I have never had an issue aligning front or rear rotors up,
The hub should have been supplied with anti rotation washers 12mm x 10mm shaped hole and two m12 washers to space the hub motor axle a little
Other wise if not you can buy them separately.
I don't see any on ebay but this on Aliexpress is the axle kit type that should have been supplied.

Thanks for the reply. I have ordered M12's from ScrewFix. Hope that will fix the problem. If not I will order the kit from your link.

Cheers.

EDIT:

Sorry for the late update. Two M12's and a wee bit of brake calibration has done the trick :).
