securing disc brake caliper bolts

Guest
I've got the quad-piston Shimano XTs and was thumbing
through the installation guide and noticed the Shimano 'stop
rings' . Little plastic caps with hooks that slide onto the
caliper mounting bolts and hook the disc tabs. I don't have
these, and don't have the slightest idea where to get them.

I have in the past lost a bolt holding my rear caliper which
rendered my rear brake usuless for the rest of the ride.

I'm wondering what folks do about this issue. Loc-
tite? Commercial products? Homemade solutions? Curious
minds, etc...

Look forwarding to hearing the ingenious solutions .

Thanks,

ashayk

Loctite works..used on motorcycle brake caliper bolts
from the factory. Use the blue so you can get them out
again. The cap is more of a visual check I think..like
safety wiring..you can visually see if your bolts are
there and secure.

Cheers,

Scott..

The XT caliper mounting bolts come drilled for lockwire, and
Shimano supply the lockwire with the brake kit.

not on the later versions - no drillings or wire. just use
thread lock.

Mine are all BR-M755 model, presumably from your post the
756 come without the drilling and lockwire. It's a simple
enough thing to drill the bolt heads and get some
lockwire from your local motorcycle race shop if you want
the extra security.

Is it common for caliper mounting bolts to come loose? My
Avids came with a thread filling substance on them. Is that
enough to keep them from vibrating loose?

Yeah, I also wondered if the mysterious Mr Kinky had ever
actually drilled a hardened bolt through the head himself
before calling that "simple".

They are a readily available fastener. If you want to safety-
wire the assembly I'd just buy those bolts.

if torqued to spec, yes, it's fine. wire is overkill.
