Removing sensor magnets from rotor bolts

Post by E.Marquez »

If any of you have ever tried to remove a brake rotor after having installed an after market speedo that uses magnets for the hall effect sensor,,, you know the pain of trying to get those little round devils out of the fastener head.

6mm socket head head cap screws are* typical of rotor fasteners, and the magnet OD is just under 6mm so they fit really close leaving no room for even a thin dental pick, or sewing needle to get in there and "pick" it out.

Stronger magnet to remove does not work either, nor does compressed air....

What does work???? The one thing that excels at gluing your fingers together but never seems to be near as "super" of a glue as the name implies.

ethyl-2-cyanoacrylate AKA Super Glue.
Clean the nice flat steel magnet, just a tiny drop of glue on a equally clean steel flat bit, say a small hex bit driver that was close at hand, the magnet even holds the two parts together for the 60 sec it takes the glue to cure.

And out it comes.

Magnet comes right off with a pair of pliers, and the dried glue with just a wipe of a bit of*acetone on a rag.

I have almost zero luck with super glue, gluing things as the TV commercial advertise, but this time it actually worked.

Id all but given up on superglue every gluing anything.

Its the wonky advertising I remember from the 80's that gave me the idea......

Wow, that clown takes me back :lol: :lol:

I noticed that there's lots of people adding baking soda to the glue to repair stuff.

Might be handy to repair chips on various items, carbon etc. :wink: :thumbup:

A top tip for stone chips on helmets is nail varnish. I take mine into the shop to colour match :thumbup:

It works very well BTW, you can fill a void quickly, no waiting on two part epoxy to cure and be work ready.
Not sure how well it works as an adhesive at that point, but as a filler, its awesome.

Also make a nice wood finish :lol:

Can you get carbon weave nail polish?
It's not falling off, it's an upgrade opportunity.
