Rear Brake Disc Bolts

Hi

I have had my rear wheel re-powder coated. When I tried to put the break disc back on. I find that I have lost the bolts.  So, I ordered some from eBay they send m8 1.25 which did not fit as the pitch wrong.  Have placed a tap to find the pitch and I find that 5/16 UNF seems to fit. I have looked at Honda parts that they say it should be m8 1.25. I have also searched for break disc bolts that are 5/16 UNF but can't find any. Its a mystery

Hi gardown.

Just to confirm the Honda disc bolts are m8 x 24 1.25 pitch part no.90105MBB000.

Firstly it looks to me in your pictures that you got sent m10 if the will not even start into the threads
You can also see that whoever powder coated your wheel did not cover the threads over so I expect they need a clean out with an m8 x 1.25 tap first.

If you search the part number in Ebay it will throw up loads of them for Honda's and other makes as it seems a standard go to bolt for discs.
Personally, I used Titanium bolts that were listed for a Ducati as they were cheaper than Honda ones.

Hope this helps you.

Ps. I always use the Fowlers parts online web page just to get the correct Honda part number before searching Ebay and beyond, it's never let me down yet for finding the correct part.

thanks for the info and reply. Is the front bolts the same m8 1.25?

Hi gardown.


Yes, to your question M8.
